mechanism分度凸轮机构 indexing cam mechanism圆柱形分度凸轮机构 cylindrical cam indexing mechanism蜗杆形分度凸轮机构 worm-cam indexing mechanism(1) Gear Teeth FormingThere are many methods of forming the teeth of gears, such as shell molding, investment casting, permanent-mold casting, die casting, centrifugal casting. Gears can also be formed by using the power-metallurgy process or by using extrusion; a single metal bar can be formed and then sliced into gear. Usually gears are cut with either form cutters or generating cutters.(2) Advantages and Disadvantages of Helical GearsHelical gears are more expensive than spur gears but offer some advantages. They operate quieter than spur gears because of smooth and gradual contact between their angle surfaces as the teeth come into mesh. Spur gear teeth mesh along their entire face width at once; the sudden impact of tooth on tooth causes vibration. Also, for the same gear diameter and module, a helical gear is stronger due to the slightly thicker tooth form in a plane perpendicular to the gear axis.The one of the disadvantages of helical gear is that they produce an axial thrust force which is harmful to the bearings. Therefore, the helix angle is limited from οο15~8.When motion is to be transmitted between shafts which are not parallel, the spur gears can not be used. Two crossed-helical gears of the same hand can be meshed with their axed at an angle, the helix angles can be designed to accommodate any skew angle between the nonintersecting shafts.(3)Characteristics of Worm GearsWorm and worm gear are used to transmit motion between two shafts which are nonparallel, nonintersecting, usually at a shaft angles of90. The worm gears have many advantages, such as larger gear ratios, small package, carrying high loads. Perhaps the major advantage of the worm set is that it can be designed to be impossible to backdrive, that is to say, it can be designed as a self-locking worm set. Therefore, worm gears are most widely used in industry. The major disadvantages is that the efficiency is lower, usually at 40% to 85%. The friction loss may result in overhearing and serious wear.(4)Classification of Gear TrainsA gear train is a combination of gears used to transmit motion from one shaft to another. Even a single pair of gear is, strictly speaking, a gear train, though the term usually suggests that there are three or more moving gears. The gear train becomes necessary when it is required to obtain large speed ratio with a small space.Gear-box is used in automobile. There are many pairs of gears to transmit different motion. Quartz watch has gear trains in which the hour hand, minute hand and second hand rotate as their definite gear ratios to indicate the times.A gear train is any collection of two or more meshing gears, such as spur gears, bevel gears, worm gears and their combination of different kinds of gears. If all gear axes remain fixed relative to the frame, train is an ordinary gear train. If one of the gear axes rotates to the frame, this gear train is an epicycle gear train.The designer is frequently confronted with the problem of transferring power from one shaft to another while maintaining a definite ratio between the velocities of rotation of the shafts. Another requirement might be the transmission of a specified angular for this purpose, which will operate quietly and with very low friction losses. Smooth and vibrationless action is secured by giving the proper geometric shape to the outline of the teeth. The proportions of the gear tooth, as well as the sizes of the teeth, have been standardized. This procedure has simplified design calculations and has reduced the required number of cutting tools to a minimum. The proper material must be selected to obtain satisfactory strength, fatigue, and wear properties. Ease of manufacture and ease of inspection are necessary if production costs are to be kept at their lowest level. All these problems must be taken into account by the designer.滚动轴承Rolling bearing一、轴承滚动体rolling element保持架cage, retainer内圈inner ring外圈outer ring滚动轴承rolling bearing单列轴承single row bearing双列轴承double row bearing球轴承ball bearing深沟球轴承deep groove ball bearing推力轴承thrust bearing推力球轴承thrust ball bearing单列双向推力球轴承single row double-direction thrust ball bearing双列单向推力球轴承double row single-direction thrust ball bearing角接触轴承angular contact bearing调心轴承self-aligning bearing滚子轴承roller bearing圆柱滚子轴承cylindrical roller bearing圆锥滚子轴承tapered roller bearing滚针轴承needle roller bearing推力滚子轴承thrust roller bearing向心球轴承radial ball bearing角接触轴承angular contact bearing调心轴承self-aligning bearing向心轴承radial bearing角接触向心轴承angular contact radial bearing单列深沟球轴承是球轴承中最普遍的种类，应用及其广泛。
机械设计简介中英文翻译
机械设计简介中英文翻译Mechanical design is the application of science and technology to devise new or improved products for the purpose of satisfying human needs. It is a vast field of engineering technology which not only concerns itself with the original conception of the product in terms of its size, shape and construction details, but also considers the various factors involved in the manufacture, marketing and use of the product.People who perform the various functions of mechanical design are typically called designers, or design engineers. Mechanical design is basically a creative activity. However, in addition to being innovative, a design engineer must also have a solid background in the areas of mechanical drawing, kinematics, dynamics, materials engineering, strength of materials and manufacturing processes.As stated previously, the purpose of mechanical design is to produce a product which will serve a need for man. Inventions, discoveries and scientific knowledge by themselves do not necessarily benefit people; only if they are incorporated into a designed product will a benefit be derived. It should be recognized, therefore, that a human need must be identified before a particular product is designed.机械设计简介机械设计是为了满足人类需要而制定出的新产品或者改进旧产品时对科学与技术的应用。

Machine design theoryThe machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and use question.Carries on each kind of machine design work to be usually called designs the personnel or machine design engineer. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge.If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of productMust regard as the machine design is the machine design personnelcarries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the completely decision which makes in a good design needs. On the other hand, should be earnest precisely carries on all operations. For example, even if places wrong a decimal point position, also can cause the correct design to turn wronglyA good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.Newly designs itself can have the question occurrence which many flaws and has not been able to expect, only has after these flaws and the question are solved, can manifest new goods come into the market the product superiority.Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphasize, if designs itself does not request to use the brand-new method, is not unnecessary merely for the goal which transform to use the new method.In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.How does the psychologist frequently discuss causes the machine which the people adapts them to operate. Designs personnel''s basic responsibility is diligently causes the machine to adapt the people. This certainly is not an easy work, because certainly does not have to all people to say in fact all is the most superior operating area and the operating process.Another important question, project engineer must be able to carry on the exchange and the consultation with other concerned personnel. In the initial stage, designs the personnel to have to carry on the exchange and the consultation on the preliminary design with the administrative personnel, and is approved. This generally is through the oral discussion, the schematic diagramand the writing material carries on. In order to carry on the effective exchange, needs to solve the following problem:(1) designs whether this product truly does need for the people? Whether there is competitive ability(2) does this product compare with other companies'' existing similar products?(3) produces this kind of product is whether economical?(4) product service is whether convenient?(5) product whether there is sale? Whether may gain?Only has the time to be able to produce the correct answer to above question. But, the product design, the manufacture and the sale only can in carry on to the above question preliminary affirmation answer foundation in. Project engineer also should through the detail drawing and the assembly drawing, carries on the consultation together with the branch of manufacture to the finally design proposalUsually, can have some problem in the manufacture process. Possibly can request to some components size or the common difference makes some changes, causes the components the production to change easily. But, in the project change must have to pass through designs the personnel to authorize, guaranteed cannot damage the product the function. Sometimes, when in front of product assembly or in the packing foreign shipment experiment only then discovers in the design some kind of flaw. These instances exactly showed thedesign is a dynamic process. Always has a better method to complete the design work, designs the personnel to be supposed unceasingly diligently, seeks these better method.Recent year, the engineerig material choice already appeared importantly. In addition, the choice process should be to the material continuously the unceasing again appraisal process. The new material unceasingly appears, but some original materials can obtain the quantity possibly can reduce. The environmental pollution, material recycling aspect and so on use, worker''s health and security frequently can attach the new limiting condition to the choice of material. In order to reduce the weight or saves the energy, possibly can request the use different material. Comes from domestic and international competition, to product service maintenance convenience request enhancement and customer''s aspect the and so on feedback pressure, can urge the people to carry on to the material reappraises. Because the material does not select when created the product responsibility lawsuit, has already had the profound influence. In addition, the material and between the material processing interdependence is already known by the people clearly. Therefore, in order to can and guarantees the quality in the reasonable cost under the premise to obtain satisfaction the result, project engineer makes engineers all to have earnestly carefully to choose, the determination and the use material.Makes any product the first step of work all is designs. Designsusually may divide into several explicit stages: (a) preliminary design; (b) functional design; (c) production design. In the preliminary design stage, the designer emphatically considered the product should have function. Usually must conceive and consider several plans, then decided this kind of thought is whether feasible; If is feasible, then should makes the further improvement to or several plans. In this stage, the question which only must consider about the choice of material is: Whether has the performance to conform to the request material to be possible to supply the choice; If no, whether has a bigger assurance all permits in the cost and the time in the limit develops one kind of new material.In the functional design and the engineering design stage, needs to make a practical feasible design. Must draw up the quite complete blueprint in this stage, chooses and determines each kind of components the material. Usually must make the prototype or the working model, and carries on the experiment to it, the appraisal product function, the reliability, the outward appearance and the service maintenance and so on. Although this kind of experiment possibly can indicate, enters in the product to the production base in front of, should replace certain materials, but, absolutely cannot this point take not earnestly chooses the material the excuse. Should unify the product the function, earnestly carefully considers the product the outward appearance, the cost and the reliability. Has the achievement very much the company when manufacture all prototypes, selects the material should the material which useswith its production in be same, and uses the similar manufacture technology as far as possible. Like this has the advantage very much to the company. The function complete prototype if cannot act according to the anticipated sales volume economically to make, or is prototypical and the official production installment has in the quality and the reliable aspect is very greatly different, then this kind of prototype does not have the great value. Project engineer is best can completely complete the material in this stage the analysis, the choice and the determination work, but is not remains it to the production design stage does. Because, is carries on in the production design stage material replacement by other people, these people are inferior to project engineer to the product all functions understanding. In the production design stage, is should completely determine with the material related main question the material, causes them to adapt with the existing equipment, can use the existing equipment economically to carry on the processing, moreover the material quantity can quite be easy to guarantee the supply.In the manufacture process, inevitably can appear to uses the material to make some changes the situation. The experience indicated that, may use certain cheap materials to take the substitute. However, in the majority situation, in will carry on the production later to change the material to have in to start before the production to change the price which the material will spend to have to be higher than. Completes the choice of material work in the design stage, may avoid the most such situations. Started after the productionmanufacture to appear has been possible to supply the use the new material is replaces the material the most common reason. Certainly, these new materials possibly reduce the cost, the improvement product performance. But, must carry on the earnest appraisal to the new material, guarantees its all performance all to answer the purpose. Must remember that, the new material performance and the reliable very few pictures materials on hand such understood for the people. The majority of products expiration and the product accident caused by negligence case is because in selects the new material to take in front of substitution material, not truly understood their long-term operational performance causes.The product responsibility lawsuit forces designs the personnel and the company when the choice material, uses the best procedure. In the material process, five most common questions are: (a) did not understand or cannot use about the material application aspect most newly the best information paper; (b) has not been able to foresee and to consider the dusk year possible reasonable use (for example to have the possibility, designs the personnel also to be supposed further to forecast and the consideration because product application method not when creates consequence.In recent years many products responsibilities lawsuit case, because wrongly uses the plaintiff which the product receives the injury to accuse produces the factory, and wins the decision); (c) uses the material data not entire perhaps some data are indefinite, works as its long-term performancedata is the like this time in particular; (d) the quality control method is not suitable and not after the confirmation; (e) the personnel which completely is not competent for the post by some chooses the material.Through to the above five questions analysis, may obtain these questions is does not have the sufficient reason existence the conclusion. May for avoid these questions to these questions research analyses the appearance indicating the direction. Although uses the best choice of material method not to be able to avoid having the product responsibility lawsuit, designs the personnel and the industry carries on the choice of material according to the suitable procedure, may greatly reduce the lawsuit the quantity.May see from the above discussion, the choice material people should to the material nature, the characteristic and the processing method have comprehensive and the basic understanding.机械设计理论机械设计是一门通过设计新产品或者改进老产品来满足人类需求的应用技术科学。

For the most part mechanical design utilizes mathematics, the materials sciences, and the engineering-mechanics sciences.The total design process is of interest to us. How does it begin? Does the engineer simply sit down at his desk with a blank sheet of paper? And, as he jots down some ideas, what happens next? What factors influence or control the decisions which have to be made? Finally, then, how does this design process end?Sometimes, but not always, design begins when an engineer recognizes a need and decides to do something about it. Recognition of the need phrasing it in so many words often constitute a highly creative act because the need may be only a vague discontent, a feeling of uneasiness, or a sensing that something is not right.The need is usually not evident at all. For example, the need to do something about a food-packaging machine may be indicated by the noise level, by the variation in package weight, and by slight but perceptible variations in the quality of the packaging or wrap.There is a distinct difference between the statement of the statement of the need and the identification of the problem which follows this statement. The problem is more specific. If the need is for cleaner air, the problem might be that of reducing the dust discharge from power-plant stacks, or reducing the quantity of irritants from automotive exhausts.Definition of the problem must include all the specifications for the thing that is to be designed. The specifications are the input and output quantities, the characteristics and dimensions of the space the thing must occupy and all the limitations on these quantities. We can regard the thing to be designed as something in a black box. In this case we must specify the inputs and outputs of the box together with their characteristics and limitations. The specifications define the cost, the number to be manufactured, the expected life, the range, the operating temperature, and the reliability.There are many implied specifications which result either from the designer’s particular environment or from the problem itself. The manufacturing processes which are available, together with the facilities of a certain plant, constitute restrictions on a designer’s freedom, and hence are a part of the implied specifications. A small plant, for instance, may not own cold-working machinery. Knowing this, the designer selects other metal-processing methods which can be performed in the plant. The labor skills available and the competitive situation also constitute implied specifications.After the problem has been defined and a set of written and implied specifications has been obtained, the next step in design is the synthesis of an optimum solution. Now synthesis cannot take place without both analysis and optimization because the system under design must be analysis and optimization because the system under design must be analyzed to determine whether the performance complies with the specifications.The design is an iterative process in which we proceed through several steps, evaluate the results, and then return to an earlier phase of the procedure. Thus we may synthesize several components of a system, analyze and optimize them, and return to syntheses to see what effect this has on the remaining parts of the system. Both analysis and optimization require that we construct or devise abstract models of the system which will admit some form of mathematical analysis. Wecall these models mathematical models. In creating them it is our hope that we can find one which will simulate the real physical system very well.Evaluation is a significant phase of the total design process. Evaluation is the final proof of a successful design, which usually involves the testing of a prototype in the laboratory. Here we wish to discover if the design really satisfies the need or needs. Is it reliable? will it compete successfully with similar products? Is it economical to manufacture and to use? Is it easily maintained and adjusted? Can a profit be made from its sale or use?Communicating the design to others is the final, vital step in the design process. Undoubtedly many great designs, inventions, and creative works have been lost to mankind simply because the originators were unable or unwilling to explain their accomplishments to others. Presentation is a selling job. The engineer, when presenting a new solution to administrative, management, or supervisory persons, is attempting to them that this solution is a better one. Unless this can be done successfully, the time and effort spent on obtaining the solution have been largely wasted.Basically, there are only three means of communication available to us. These are the written, the oral. And the graphical forms. Therefore the successful engineer will be technically competent and versatile in all three forms of communication. A technically competent person who lacks ability in any one of these forms is severely handicapped. If ability in all three forms is locking, no one will ever know how competent that person is!The competent engineer should not be afraid of the possibility of not succeeding in a presentation. In fact, occasional failure should be expected because failure or criticism seems to accompany every really creative idea. There is a great deal to be learned form a failure, and the greatest gains are obtained by those willing to risk defeat. In the final analysis, the real failure would lie in deciding not to make the presentation at all.机械设计基础机械设计是指机械装置和机械系统——机器、产品、结构、设备和仪器的设计。

Mechanical DesignAbstract:A machine is a combination of mechanisms and other components which transforms, transmits, or utilizes energy, force, or motion for a useful purpose. Examples are engines, turbines, vehicles, hoists, printing presses, washing machines, and movie cameras. Many of the principles and methods of design that apply to machines also apply to manufactured articles that are not true machines, from hub caps and filing cabinets to instruments and nuclear pressure vessels. The term "mechanical design" is used in a broader sense than "machine design" to include their design. For some apparatus, the thermal and fluid aspects that determine the requirements of heat, flow path, and volume are separately considered. However, the motion and structural aspects and the provisions for retention and enclosure are considerations in mechanical design. Applications occur in the field of mechanical engineering, and in other engineering fields as well, all of which require mechanical devices, such as switches, cams, valves, vessels, and mixers.Keywords: Mechanical Designmechanisms Design Process ToleranceDesign processThe design begins from real of or the demand of imagination.The existing instrument may need to take in to improve on the enduring, efficiency, weight, speed or the cost.May need new instrument to complete before function done by person, such as Assemble or maintain.The target is all or partly after making sure, design of the next move is to conceive outline the organization that can complete the function needed and it arranges for this, drawing grass diagram to be worth barehanded biggest, it isn't only one personal record of viewpoint with with others discussion of assistance means, and be suitable for to communicate with own viewpoint particularly, is the stimulant which creates sex way of thinking to still need extensive knowledge concerning parts, because a the set new machine usually from be familiar with of each kind of spare parts reschedule or substitute but become, changed size and material perhaps.Regardless at conceive outline process in still after, a design will carry on a fast or rough calculation or analyze to make sure regulation size and possibility.When some concerning need or can use amount of space of viewpoint assurance after, can start pro rata painting grass diagram.Finally, 1 completed according to the design of the function and the credibility, can make kind machine.If test satisfied, and if the device wants mass production, will to the first design carry on a certain modification to insure with lower cost ter on several years of make and use a period, design probably because of conceive outline new viewpoint perhaps according to test and experience foundation of further analytical the change shown but change.Sell attraction, customer's satisfaction and manufacturing costs to all have something to do with design, the success which designs ability and engineering investment is closelyrelated.Some design standardsAt this part, someone suggests the attitude of the usage creation carries on of analysis, this kind of analysis can cause a graveness improvement and to back up the product conceive outline with perfect, perhaps the product function is more, more economic and more enduring.Creating the stage's needing not is first with independent stage.Although analyze personnel the whole probably irresponsible design, he isn't only the right answer of[with] problem that can be from the numeral put forward wanting him to resolve only, not only only is give should dint value, the size works to limit perhaps.He can put forward more extensive views, for the purpose of improvement norm or project.Because in the analysis the front or the analysis the process, he will acquaint with to equip and its work condition, he is fully placed in a beneficial position which conceives outline to choose a project.Best he can put forward a suggestion change shape to Elimination moment of force or should dint concentration, not allow to set up to have to cut the organization that noodles and excessive dynamic state carry a lotus greatly best is he discards his meticulous of design but is not see a machine discard afterwards.For stiring up to create sex thinking, the suggestion designs a personnel and analytical the personnel use following standard.6 ex- standards are particularly applicable to an analysis personnel, although he may involve to all this 10. 1.Create the physical function that sex land utilization need when using combine the control don't need.2.Know practical carry lotus and its importance.3.Consider in advance there is no function carrying a lotus.4.Invent to add to carry a condition more beneficially.5.Provide minimum weight the most beneficial of distribute in response to the dint with rigid.e a basic and square distance calculation a comparison and make size superior to turn.7.Select by examinations material to acquire a function combination.8.At spare parts and integrated spare parts careful choice.9.Modify a function design with the orientation production line and decline low cost.10.Consider to make parts accurate to position in the assemble with with each other not interferenceMechanical DesignThe whole machine design is a complicated process.Designing the personnel have to at thus of realm, such as calm down mechanics, kinetics, dynamics and material mechanics have good cultivated manners, have to also acquaint with manufacturing material and make a craft in addition.Designing the personnel has to can combine all related facts, carrying on Teaches Wei and creating grass diagram and graphics to come to deliver the manufacturing request to the car.The square one that any product designs works it an is the material that the choice useds for making each parts.The design personnel of today can get an innumerable.While choosing, function, external appearance, material cost andmanufacturing costs of product are all very important.Had to be careful to evaluate the function of material before any calculation.It is necessary a careful calculation with the usefulness of insuring the pute to never appear on the diagram, but from ten various reason be saved.Once the whichever parts loses efficacy, will clear up to do what while designing this defective spare parts at the beginning;And, can acquire an experience document from compute past item.While needing the design for ising similar to, the past record will have a tremendous help.The check of computing(with diagram top size) is the most important.A decimal point's mislaying position can ruin an original and acceptable item.For example, if a person wants to design a bracket that can prop up 100 pounds, but it should can prop up 1000 pounds originally, the result affirmation will fail.The square aspect noodles had to check a check to design again a work.The calculator speaks to is an of great use tool for the staff member, can ease a dull calculation and provide to expand analysis to the existing data. Hand over system to make the calculator assistance design(CAD) with each other according to the calculator function and the calculator lend support to a manufacturing(CAM) to make possible.Pass thus of system, may conceive outline a first step to deliver to beat bore paper to take to used for numeral to process control but need not to draw formal construction diagram.The machine design for the laboratory test, model and kind machine is very helpful.The laboratory provided a lot of build up basic concept need of information, however, can also acquire with them some concerning product how on the spot would the understanding for working.Finally, a design personnel of success should offer the step that the utmost effort keeps up with ages.Will appear new material and produce a method everyday.If painting and design personnel's don't acquainting with modern method and material may put out action.A good design personnel should usually read technique periodical to keep up with a new developmentThe engineering work is badThe solid is made sure boundary by its surface boundary.Typical model ground, design a personnel to specify Mr. to call size to a spare parts to make it contented its demand.Actually because of the surface irregular and proper surface rough degree, each spare parts can't make into Mr. to call size's hasing to allow size to have some varieties can make with insuring repeatedly.But, the variety allowed can't certainly too big with as for make to assemble the function of the piece to become bad.Single the variety allowed by spare parts is called business trip.Business trip this technical term not only is applicable to from the acceptable scope of the parts size of[with] manufacturing craft creation, but also is applicable to a machine or processes of exportation.For example, a give already set number of thepower each pedestals of I.C. engine have variety.Actually, we usually discover this kind of variety model will be a frequency to distribute curve, for example t.The distributes.(call the Gauss distribute again)One of the work which designs a personnel is the variety which specifies size for a spare parts and allows, thisvalue canproduce acceptable function.Spare parts business tripWhen there is no appointed accurate size in the diagram, most organizations all have in general use business trip of being applicable to the size.For process size, in gene ral use business trip's maying be a ± is 0.5 millimeters.Therefore being specified to 15.0 millimeter scopes of sizes can be of 14.5-15.5 millimeters.Other in general use business trips can be applicable to such as the angle and drill a hole with blunt bore, The casting, the forging, the welded joint and weld the angle）etc. situation.Can make reference to the diagram of past or general engineering to practice while giving the appointed business trip of a spare parts.The business trip of typical model's ising specified is martial become JSO standard define of range.Give to settle business trip to 1, for example H7/s 6, can use for being studying of spare parts size having 1 set and chart to shoulding of number.Underneath this will give concerning pack into inside bore of the concrete example with the stalk or the pillar form match.The standard match of bore and stalkA standard of the engineering work is the business trip which makes sure a pillar form spare parts, installing for example in a tube form spare parts or bore for corresponding of.perhaps is the stalk which revolves in its inner part to match with of loose be decided by application tightly for example, a wheel gear which positions on the stalk needs to be"tight" of quiet match, here stalk of the diameter compares wheel gear actually of inside path a little bit a little bit big in order to can deliver need of Torque .Furthermore, the diameter of glide bearings has to be big in the diameter of the stalk to make it revolve.On the supposition that speak to can't become the accurate size to the parts manufacturing from the economy, all of the variety of stalk and bore size have to make sure.But, variety of scope shouldn't the too big in order to prevent assemble hour damagedFor being unlikely to there is everlasting drive appointed business trip size endlessly, have already drawn up national and international standard to make sure business trip to take, for example hll/cll.For using this data, gave the definition in the traditional business trip ually what to use is the Basic hole system, because this meeting makes company internal auger needed, wring knife and pull knife and calculate the decrease of tool category.Size:Mean the number of the size numerical value by appropriation unit. Actual size:The parts size got through a diagraphSize extreme limit:The spare parts allows of biggest with most baby size.The biggest size extreme limit:Bigger in two size extreme limitsMost baby size extreme limit:Smaller in two size extreme limits ofBasic size:Fix the reference size of size extreme limit in order toDeviation:A size with it to should of the algebra of basic size badActual deviation:Actual size with it to should of the algebra of basic size bad. Last deviation:The biggest size extreme limit with it to should of the algebra of basic size badDescend deviation:Most baby size extreme limit with it to should of the algebra of basic size badBusiness trip:The biggest size extreme limit with most the bad value of baby size extreme limit.Stalk:Specifying an exterior characteristics with all parts consistently uses technical termBore:Specify a parts all internal characteristics to consistently use technical term.The initial design creation satisfies appointed demanding solution.The initial design can represent all sub- systems of constituting the whole system with the total of zero partses.Ion and Smith describe an initial design for is become by a series and evaluate a stage to constitute of an iterative process, each stage matches together to become a good solution.At each iterative stage conceive outline more in detail, can more overall valuation.Produce possibly many of or the economy is convenient of conceive outline and the viewpoint is important.There is 1 kind to lure, let you accept the first hopeful conceive outline and carry on a detailed design until end product.Should resist this kind of come-on, because of so as a result the head quarter is more quite a few.Well worth mentioning BE, or early or late your design would have to with those designs competitions which come from other manufactories, so the creation develop of the thoughts should be careful.Is to them to carry on valuation to combine choice next move after producing viewpoint and conceiving outline the best conceive outline.a kind of valuation method is to use row watch matrix.The matrix constitutes to°from a series of standard. conceive outline have to ask for help them to beat a cent.If suitable, the importance of the standard can add power, conceiving outline most in keeping withly will have a tallest total cent.This method provided a built-up valuation technique. and make personal viewpoint that can hardly promote their own absurdity in the team.Produced the solution of first step, the next move was to express them, in order to they ability and all involve total design process of the persons communicate actually, this one step can adopt forms of drawing the grass diagram or 3D models, since but physical model also but the calculator born model. Of the total plan has been completed and calculated to determine solutions for product design compatibi- Lity, details of the design phase had been created.机械设计摘要机器是机构与其他零件的组合，为了有益的用途而转换、传递或利用能量、力或者运动实例有发动机、涡轮、车辆、卷扬机、印刷机、洗衣机和电影摄影机.许多适用于机器设计的原理和力法也适用于不是真正机器的制成品，从轮毂盖和档案橱柜到仪表和核压力容器。

机械英汉翻译-机械设计概论
Introduction to Machine DesignMachine design is the application of science and technology to devise new Or improved products for the purpose of satisfying human needs．It is a vast field of engineering technology which not only concerns itself with the original conception of the product in terms of its size，shape and construction details，but also considers the various factors involved in the manufacture，marketing and use of the product．People who perform the various functions of machine design are typically called designers，or design engineers．Machine design is basically a creative activity．However，in addition to being innovative，a design engineer must also have a solid background in the areas of mechanical drawing，kinematics，dynamics, materials engineering, strength of materials and manufacturing processes.As stated previously，the purpose of machine design is to produce a product which will serve a need for man．Inventions，discoveries and scientific knowledge by themselves do not necessarily benefit people；only if they ale incorporated into a designed product will a benefit be derived．It should be recognized，therefore，that a human need must be identified before a particular product is designed．Machine design should be considered to be an opportunity to use innovative talents to envision a design of a product，to analyze the system and then make sound judgments on how the product is to be manufactured．It is important to understand the fundamentals of engineering rather than memorize mere facts and equations．There are no facts or equations which alone can beused to provide all the correct decisions required to produce a good design．On the other hand，any calculations made must be done with the utmost care and precision．For example，if a decimal point is misplaced，an otherwise acceptable design may not function．Good designs require trying new ideas and being willing to take a certain amount of risk，knowing that if the new idea does not work the existing method call be reinstated．Thus a designer must have patience，since there is no assurance of success for the time and effort expended．Creating a completely new design generally requires that many old and well．established methods be thrust aside．This is not easy since many people cling to familiar ideas，techniques and attitudes．A design engineer should constantly search for ways to improve all existing product and must decide what old，proven concepts should be used and what new，untried ideas should be incorporated．New designs generally have “bugs” or unforeseen proble ms which must be worked out before the superior characteristics of the new designs can be enjoyed. Thus there is a chance for a superior product．but only at higher risk．It should be emphasized that，ifa design does not warrant radical new methods，such methods should not be applied merely for the sake of change．During the beginning stages of design，creativity should be allowed to flourish without a great number of constraints．Even though many impractical ideas may arise，it is usually easy to eliminate them in the early stages of design before firm details are required by manufacturing．In this way，innovative ideas are not inhibited．Quite often，more than one design is developed，up to the point where they call be compared against each other．It is entirely possible that the design which is ultimately accepted will use ideas existing in one of the rejected designs that did not show as much overall promise．Psychologists frequently talk about trying to fit people to the machines they operate．It is essentially the responsibility of the design engineer to strive to fit machines to people．This is not an easy task，since there is really no average person for which certain operating dimensions and procedures are optimum．Another important point which should be recognized is that a design engineer must be able to communicate ideas to other people if they ale to be incorporated．Initially，the designer must communicate a preliminary design to get management approval．This is usually done by verbal discussions in conjunction with drawing layouts and written material．To communicate effectively，the following questions must be answered：(1Does the design really serve a human need?(2Will it be competitive with existing products of rival companies?(3Is it economical to produce?(4Can it be readily maintained?(5Will it sell and make a profit?Only time will provide the true answers to the preceding questions，but the product should be designed，manufactured and marketed only with initial affirmative answers．The design engineer also must communicate the finalized design to manufacturing through the use of detail and assembly drawings．Quite often，a problem will occur during the manufacturing cycle．It may be that a change is required in the dimensioning or tolerancing of a part 80 that it can be more readily produced．This falls in the category of engineering changes which must be approved by the design engineer so that the product function will not be adversely affected．In other eases，a deficiency in the design may appear during assembly or testing just prior to shipping．These realities simply bear out the fact that design is aliving process．There is always a better way to do it and the designer should constantly strive towards finding that better way．A new machine is born because there is a real or imagined need for it．It evolves from Someone’s conception of a device with which to accomplish a particular purpose．From the conception follows a study of the arrangement of the parts，the location and length of links (which may include a kinematic study of the linkage，the places for gears，bolts，springs，cams，and other elements of machines．With all ideas subject to change and improvement，several solutions may be and usually are found，the seemingly best one being chosen．The actual practice of designing is applying a combination of scientific principles and a knowing judgment based on experience．It is seldom that a design problem has only one right answer，a situation that is often annoying to the beginner in machine design．Engineering practice usually requires compromises．Competition may require a reluctant decision contrary to one’s best engineering judgment；production difficulties may force a change of design；etc．A good designer needs many attributes，for example：(1A good background in strength of materials，SO that the stress analyses are sound．The parts of the machine should have adequate strength and rigidity, or other characteristics as needed．(2A good acquaintance with the properties of materials used in machines．(3A familiarity with the major characteristics and economics of various manufacturing processes，because the parts that make up the machine must be manufactured at a competitive cost．It happens that a design that is economic for one manufacturing plant may not be so for another. For example，a plant with a well-developed welding department but no foundry might t5nd that welding IS the most economic fabricating method in a particular situation；whereas another plant faced with the same problem might decide upon casting because they have a foundry (and may or may not have a welding department．(4A specialized knowledge in various circumstances，such as the properties of materials in corrosive atmospheres，at very low (cryogenic temperatures，or at relatively high temperatures．(5A preparation for deciding wisely：(awhen to use manufacturers’ catalogs，buying stock or relatively available items，and when custom design is necessary；(b when empirical design is justified；(Cwhen the design should be tested in service tests beforemanufacture starts；(d when special measures should be taken to control vibration and sound (and others．(6Some aesthetic sense，because the product must have ”customer appeal” if it is to sell．(7A knowledge of economics and comparative costs，because the best reason for the existence of engineers is that they save money for those who employ them．Anything that increases the cost should be justified by, for instance，an improvement in performance，the addition of an attractive feature，or greater durability．(8Inventiveness and the creative instinct，most important of all for maximum effectiveness．Creativeness may arise because an energetic mind is willing to act．is dissatisfied with something as it is and this mind is willing to act．Naturally, there are many other important considerations and a host of details．Will the machine be safe to operate? Is the operator protected from his own mistakes and carelessness? Is vibration likely to cause trouble? Will the machine be too noisy? Is the assembly of the pans relatively simple? Will the machine be easy to service and repair? Of course，no one engineer is likely to have enough expert knowledge concerning the above attributes to make optimum decisions on every question．The larger organizations will have specialists to perform certain functions，and smaller ones can employ consultants. Nevertheless, the more any one engineer knows about all phases of design, the better. Design is an exacting Profession，but highly fascinating when practiced against a broad background of knowledge．译文机械设计概论机械设计是一门通过设计新产品或者改进老产品来满足人类需求的应用技术科学。

机械设计理论The machine design theoryThe machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and use question.Carries on each kind of machine design work to be usually called designs the personnel or machine design engineer. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge.If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of productMust regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the completely decision which makes in a good design needs. On the other hand, should be earnest precisely carries on all operations. For example, even if places wrong a decimal point position, also can cause the correct design to turn wrongly.A good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.Newly designs itself can have the question occurrence which many flaws and has not been able to expect, only has after these flaws and the question are solved, can manifest new goods come into the market the product superiority. Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphas ize, if designs itself does not request to use the brand-new method, is not unnecessary merely for the goal which transform to use the new method.In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint. Even if has had many impractical ideas, also can in the design early time, namely in front of the plan blueprint is corrected. Only then, only then does not send to stops up the innovation the mentality. Usually, must propose several sets of design proposals, then perform the comparison. Has the possibility very much in the plan which finally designated, has used certain not in plan some ideas which accepts.How does the psychologist frequently discuss causes the machine which the people adapts them to operate. Designs personnel''s basic responsibility is diligently causes the machine to adapt the people. This certainly is not an easy work, because certainly does not have to all people to say in fact all is the most superior operating area and the operating process.Another important question, project engineer must be able to carry on the exchange and the consultation with other concerned personnel. In the initial stage, designs the personnel to have to carry on the exchange and the consultation on the preliminary design with the administrative personnel, and is approved. This generally is through the oral discussion, the schematic diagram and the writing material carries on. In order to carry on the effective exchange, needs to solve the following problem:(1) designs whether this product truly does need for the people? Whether there is competitive ability(2) does this product compare with other companies'' existing similar products?(3) produces this kind of product is whether economical?(4) product service is whether convenient?(5) product whether there is sale? Whether may gain?Only has the time to be able to produce the correct answer to above question. But, the product design, the manufacture and the sale only can in carry on to the above question preliminary affirmation answer foundation in. Project engineer also should through the detail drawing and the assembly drawing, carries on the consultation together with the branch of manufacture to the finally design proposal.Usually, can have some problem in the manufacture process. Possibly can request to some components size or the common difference makes some changes, causes the components the production to change easily. But, in the project change must have to pass through designs the personnel to authorize, guaranteed cannot damage the product the function. Sometimes, when in front of product assembly or in the packing foreign shipment experiment only then discovers in the design some kind of flaw. These instances exactly showed the design is a dynamic process. Always has a better method to complete the design work, designs the personnel to be supposed unceasingly diligently.Recent year, the engineerig material choice already appeared importantly. In addition, the choice process should be to the material continuously the unceasing again appraisal process. The new material unceasingly appears, but some original materials can obtain the quantity possibly can reduce. The environmental pollution, material recycling aspect and so on use, worker''s health and security frequently can attach the new limiting condition to the choice of material. In order to reduce the weight or saves the energy, possibly can request the use different material. Comes from domestic and international competition, to product service maintenance convenience request enhancement and customer''s aspect the and so on feedback pressure, can urge the people to carry on to the material reappraises. Because the material does not select when created the product responsibility lawsuit, has already had the profound influence. In addition, the material and between the material processing interdependence is already known by the people clearly.Therefore, in order to can and guarantees the quality in the reasonable cost under the premise to obtain satisfaction the result, project engineer makes engineers all to have earnestly carefully to choose, the determination and the use material.Makes any product the first step of work all is designs. Designs usually may divide into several explicit stages: (a) preliminary design; (b) functional design; (c) production design. In the preliminary design stage, the designer emphatically considered the product should have function. Usually must conceive and consider several plans, then decided this kind of thought is whether feasible; If is feasible, then should makes the further improvement to or several plans. In this stage, the question which only must consider about the choice of material is: Whether has the performance to conform to the request material to be possible to supply the choice; If no, whether has a bigger assurance all permits in the cost and the time in the limit develops one kind of new material.In the functional design and the engineering design stage, needs to make a practical feasible design. Must draw up the quite complete blueprint in this stage, chooses and determines each kind of components the material. Usually must make the prototype or the working model, and carries on the experiment to it, the appraisal product function, the reliability, the outward appearance and the service maintenance and so on. Although this kind of experiment possibly can indicate, enters in the product to the production base in front of, should replace certain materials, but, absolutely cannot this point take not earnestly chooses the material the excuse. Should unify the product the function, earnestly carefully considers the product the outward appearance, the cost and the reliability. Has the achievement very much the company when manufacture all prototypes, selects the material should the material which uses with its production in be same, and uses the similar manufacture technology as far as possible. Like this has the advantage very much to the company. The function complete prototype if cannot act according to the anticipated sales volume economically to make, or is prototypical and the official production installment has in the quality and the reliable aspect is very greatly different, then this kind of prototype does not have the great value. Project engineer is best can completely complete the material in this stage the analysis, the choice and the determination work, but is not remains it to the production design stage does. Because, is carries on in the production design stage material replacement by other people, these people are inferior to project engineer to the product all functions understanding.In the production design stage, is should completely determine with the material related main question the material, causes them to adapt with the existing equipment, can use the existingequipment economically to carry on the processing, moreover the material quantity can quite be easy to guarantee the supply.In the manufacture process, inevitably can appear to uses the material to make some changes the situation. The experience indicated that, may use certain cheap materials to take the substitute. However, in the majority situation, in will carry on the production later to change the material to have in to start before the production to change the price which the material will spend to have to be higher than. Completes the choice of material work in the design stage, may avoid the most such situations. Started after the production manufacture to appear has been possible to supply the use the new material is replaces the material the most common reason. Certainly, these new materials possibly reduce the cost, the improvement product performance. But, must carry on the earnest appraisal to the new material, guarantees its all performance all to answer the purpose. Must remember that, the new material performance and the reliable very few pictures materials on hand such understood for the people. The majority of products expiration and the product accident caused by negligence case is because in selects the new material to take in front of substitution material, not truly understood their long-term operational performance causes.The product responsibility lawsuit forces designs the personnel and the company when the choice material, uses the best procedure. In the material process, five most common questions are: (a) did not understand or cannot use about the material application aspect most newly the best information paper; (b) has not been able to foresee and to consider the dusk year possible reasonable use (for example to have the possibility, designs the personnel also to be supposed further to forecast and the consideration because product application method not when creates consequence.In r ecent years many products responsibilities lawsuit case, because wrongly uses the plaintiff which the product receives the injury to accuse produces the factory, and wins the decision); (c) uses the material data not entire perhaps some data are indefinite, works as its long-term performance data is the like this time in particular; (d) the quality control method is not suitable and not after the confirmation; (e) the personnel which completely is not competent for the post by some chooses the material.Through to the above five questions analysis, may obtain these questions is does not have the sufficient reason existence the conclusion. May for avoid these questions to these questions research analyses the appearance indicating the direction. Although uses the best choice of material method not to be able to avoid having the product responsibility lawsuit, designs thepersonnel and the industry carries on the choice of material according to the suitable procedure, may greatly reduce the lawsuit the quantity.May see from the above discussion, the choice material people should to the material nature, the characteristic and the processing method have comprehensive and the basic understanding.机械设计理论机械设计是一门通过设计新产品或者改进老产品来满足人类需求的应用技术科学。

机械设计理论The machine design theoryThe machine design is through designs the new product or improves the old product to meet the human need the application technical science. It involves the project technology each domain, mainly studies the product the size, the shape and the detailed structure basic idea, but also must study the product the personnel which in aspect the and so on manufacture, sale and use question.Carries on each kind of machine design work to be usually called designs the personnel or machine design engineer. The machine design is a creative work. Project engineer not only must have the creativity in the work, but also must in aspect and so on mechanical drawing, kinematics, engineerig material, materials mechanics and machine manufacture technology has the deep elementary knowledge.If front sues, the machine design goal is the production can meet the human need the product. The invention, the discovery and technical knowledge itself certainly not necessarily can bring the advantage to the humanity, only has when they are applied can produce on the product the benefit. Thus, should realize to carries on before the design in a specific product, must first determine whether the people do need this kind of productMust regard as the machine design is the machine design personnel carries on using creative ability the product design, the system analysis and a formulation product manufacture technology good opportunity. Grasps the project elementary knowledge to have to memorize some data and the formula is more important than. The merely service data and the formula is insufficient to the completely decision which makes in a good design needs. On the other hand, should be earnest precisely carries on all operations. For example, even if places wrong a decimal point position, also can cause the correct design to turn wrongly.A good design personnel should dare to propose the new idea, moreover is willing to undertake the certain risk, when the new method is not suitable, use original method. Therefore, designs the personnel to have to have to have the patience, because spends the time and the endeavor certainly cannot guarantee brings successfully. A brand-new design, the request screen abandons obsoletely many, knows very well the method for the people. Because many person of conservativeness, does this certainly is not an easy matter. A mechanical designer should unceasingly explore the improvement existing product the method, should earnestly choose originally, the process confirmation principle of design in this process, with has not unified it after the confirmation new idea.Newly designs itself can have the question occurrence which many flaws and has not been able to expect, only has after these flaws and the question are solved, can manifest new goods come into the market the product superiority. Therefore, a performance superior product is born at the same time, also is following a higher risk. Should emphas ize, if designs itself does not request to use the brand-new method, is not unnecessary merely for the goal which transform to use the new method.In the design preliminary stage, should allow to design the personnel fully to display the creativity, not each kind of restraint.
