This course will give you an introduction to SKF bearings and consists of three sections: Functions and parts,Applications and bearing types,and Designations.Module 1: Functions and partsWhy bearings?Bearings are an essential component of almost all machinery. They transmit loads between, support, guide and locate, machine elements that are required to move relative to each other with a minimum of friction, e.g.a rotating or oscillating shaft, pivot or wheel.Friction: Page 1Friction counteracts the movement between two surfaces. It is essential for the success of many operations, such as a car tyre gripping a road. In most machines however, friction is undesirable since it causes power loss, heat generation, wear and noise. SKF bearings help reduce friction.Friction: Page 2The earliest bearings were mostly made of wood and consisted of a shaft rotating in a hole in a housing, or a wheel rotating on a stationary shaft. Because the components were sliding over each other, friction was relatively high and wear rather rapid.This type of bearing is called a plain bearing and, made of modern materials, is still used in some applications today where speeds and loads are relatively low.Friction: Page 3The introduction of rolling elements between the shaft and the housing greatly reduces friction.Friction: Page 4Today, typical SKF rolling bearings combine maximum load capacity with minimum friction, using hardened steel or ceramic rolling elements, hardened steel inner and outer rings and a cage to guide and separate the rolling elements.Loads: Page 1A bearing can be under radial load, perpendicular to the shaft, or under axial load, acting in the direction along the shaft, or a combination of both radial and axial load, a combined load.Loads: Page 2Large bearings support heavier loads than small bearings can support, and roller bearings support heavier loads than ball bearings can support. Raceway contactThe basic difference between ball bearings and roller bearings is in the contacts between the rolling elements and the raceways. Balls have point contact; rollers have linear contact with relatively larger area.Bearing partsA typical rolling bearing consists of an inner ring, an outer ring and rolling elements contained by a cage. The most common type of rolling bearing is the deep groove ball bearing. These bearings can, as shown here, be supplied with integral seals to retain the lubricant and resist the ingress of contamination.Selection factorsThere are many factors, which will affect the choice of a bearing. These are: Available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Selection factors: SpaceSpace can be an important factor in bearing selection. Where radial space is limited a bearing with small diameter rolling elements, such as a needle roller bearing, may be needed.Selection factors: LoadWhen selecting a bearing, it is important to consider the direction of the load, and the amount of load the bearing will have to carry. A bearing can be under radial load, axial load, or a combination of both.Selection factors: Required service lifeThe life of a bearing can be expressed in terms of: the number of revolutions before failure, the number of operating hours before failure, or the distance covered (for cars and trucks). A bearing is considered to have failed when it shows the first sign of fatigue in a rolling element or raceway, or damage to other parts such as the cage or the seals. Service life is the real life that an individual bearing achieves in a particular application before it has to be replaced. It depends on a variety of influencing factors, including lubrication, the degree of contamination, misalignment, proper installation, and environmental conditions.Because service life cannot be calculated or predicted, bearings are selected using calculated rating life. SKF rating life L10m, a reference value calculated according to statistical methods, using modification factors for lubrication conditions and degree of contamination, and applying the same concept of a fatigue load limit as used in ISO 281, to estimate the life, with 90% reliability, that a sufficiently large population of apparently identical bearings might achieve when all are operating in an identical application.Selection factors: MisalignmentWhere a bearing is likely to be subject to angular misalignment, for example the shaft might bend due to operating loads, appropriate bearings need to be selected. Self-aligning bearings can accept a degree of operational misalignment and can also compensate for limited initial alignment errors in mounting.Selection factors: SpeedThe maximum speed that a bearing can be run in an application is limited by the maximum operating temperature for the materials used in its manufacture, or the lubricant. For high-speed applications minimum possible friction is important, so ball bearings are generally used. Selection factors: StiffnessElastic deformation occurs under load. Usually this deformation is very small and can be ignored. However, in some applications, stiffness is an important factor. Roller bearings have higher stiffness than ball bearings due to the larger area of the line contact.Selection factors: Axial displacementSome applications require bearings that allow the shaft to move axially relative to the bearing. This is called axial displacement. Most often, a shaft is supported by a locating bearing and a non-locating bearing. The locating bearing does not allow axial displacement and keeps the shaft in position. The non-locating bearing supports the shaft and allows displacement to prevent the bearings from being stressed. Cylindrical and CARB toroidalroller bearings can accommodate a limited degree of axial internal displacement.Selection factors: ClearanceThe amount of initial internal radial clearance required in a bearing depends mainly on the fits and temperature gradient between the inner and outer rings of the bearing in the particular application. Operational internal radial clearance is almost always less than initial internal clearance. SKF manufactures bearings with the following ranges of radial internal clearances:•C1 radial internal clearance less than C2•C2 radial internal clearance less than Normal•-- Normal radial internal clearance•C3 radial internal clearance greater than Normal•C4 radial internal clearance greater than C3SummaryIn this lesson, you have learnt about the functions of a bearing. These are: reducing friction, transmitting loads, locating and guiding moving parts. You have also been introduced to the different parts of a bearing: outer and inner rings, rolling elements, cage, and seals and their respective functionalities.Finally, you have also explored the different selection factors, which will affect your choice of bearing: available space, load, required service life, misalignment, speed, stiffness, axial displacement and clearance.Module 2: ApplicationsIntroductionIn this section you will be introduced to the most common bearing types offered by SKF.Electrical motors can be found almost anywhere there is mechanical movement.Motor: Page 2In this drawing you can see that the shaft is supported by two different bearings.Motor: Page 3Cylindrical roller bearings are simply bearings with cylindrical rollers. They can usually accommodate heavy radial loads and can operate at relatively high speeds.Motor: Page 4It is now time to choose the right side bearing.Motor: Page 5Deep groove ball bearings have deep uninterrupted raceways and close osculation between balls and raceways. This enables them to take axial loads in both directions.Pump: Page 1A pump is a device for lifting, transferring or moving fluids by suction or pressure from one position to another. This picture shows a medium-duty process pump, which is often used in refineries.Pump: Page 2In this drawing you can see that the shaft, which is running the impeller, is supported by one deep groove ball bearing to the right, and another bearing or bearings to the left.Single row angular contact ball bearings are widely used in medium and heavy-duty centrifugal pumps. They have raceways arranged at an angle to the bearing axis.Pump: Page 4Single row angular contact ball bearings can only take axial load in one direction. Therefore they are nearly always mounted as pairs in back to back or face to face arrangement at either end of a shaft, or as shown here, universally matchable bearings mounted immediately adjacent to each other.Fan: Page 1This is an industrial fan, in which SKF bearings are commonly used. Industrial fans can either be designed for light loads and high speeds, or for heavy loads and moderate speeds.Fan: Page2A fan is designed with two bearings along its shaft, placed between the fan and the motor. Both bearings carry radial loads and the bearing closest to the fan (on the left hand side here) also needs to be a locating bearing, keeping the shaft and the fan in a fixed position.Fan: Page 3Spherical roller bearings have two rows of rollers with a common raceway in the outer ring. The two inner ring raceways are inclined at an angle to the bearing axis.Fan: Page 4Returning to the fan application again, you now know which bearing is suitable as the locating bearing and here you have to make a guess concerning the non-locating bearing.CARB [ka:b] is a single row toroidal roller bearing with long, slightly crowned, rollers and concave raceways in both the inner and outer rings. Fan: Page 6The complete application looks like this with one spherical roller bearing and one CARB toroidal roller bearing.Separator: Page 1Alfa Laval, a Swedish company, has developed a range of machines specifically designed for rigorous oil processing duties. An example of this would be separators.Separator: Page 2The separation process creates imbalance due to the mud, which is distributed unevenly inside the separator and this makes the spindle bend. Separator: Page 3Self-aligning ball bearings have two rows of balls and a common concave sphered raceway in the outer ring. This makes the bearing insensitive to angular misalignments of the shaft relative to the housing. Self-aligning ball bearings accommodate high speeds due to the point contact between balls and raceways.Refiner: Page 1SKF bearings can be used in refiners in the production of mechanical pulp and other high-yield pulps.Refiner: Page 2In the process wood chips are ground at high mechanical pressure between a stationary disc and a rotating disc, which is powered by an electrical motor. The shaft between the motor and the grinding discs is supported by three bearings.Refiner: Page 3The high production capacity of the refiners is directly related to the demands on the bearing arrangement. The bearings have to provide high stability, operate at high speed, carry high thrust loads and handle deflections of the shaft.Refiner: Page 4The spherical roller thrust bearing incorporates a large number of asymmetrical, spherical rollers and has specially designed raceways. The load is transmitted from one raceway to the other at an angle to the bearing axis and the bearing can carry heavy axial load in one direction and some simultaneously applied radial load as well.Refiner: Page 5This is how the spherical roller thrust bearings are situated in the refiner application.Screw conveyor: Page 1Machines used in the agricultural industry often require bearings that can easily be changed and that can handle misalignments.Screw conveyor: Page 2This is a drawing of a screw conveyor attached to an agricultural machine. The bearings are the only contact between the screw conveyor and the machine.Screw conveyor: Page 3A Y-bearing unit consists of two parts: a housing and a bearing. The bearing is based on the deep groove ball bearing and can carry light radial and axial loads. It has a convex-sphered outside diameter, which allows the bearing to take up misalignment between the shaft and housing at the assembly stage. They are available with a wide range of highly effective,integral seals and a range of different methods for easy mounting to the shaft.Screw conveyor: Page 4This is what the Y-bearing unit looks like in the screw conveyor.Front wheel: Page 1SKF bearings are used in front wheels of commercial vehicles. These applications require bearings that can handle very heavy loads.Front wheel: Page 2This drawing shows how a truck front wheel arrangement is designed and where its bearings are situated. The bearings must carry a large part of the weight of the vehicle and the induced forces when driving, which means that they have to handle heavy loads in both radial and axial directions.Front wheel: Page 3Tapered roller bearings have tapered rollers running in tapered inner and outer ring raceways. This design makes them suitable for handling heavy combined loads.A tapered roller bearing can only carry axial loads in one direction and, for this reason, they are generally fitted in pairs.Front wheel: Page 4See how the tapered roller bearings are mounted in the front wheel of a commercial vehicle.SummaryIn this lesson, you have studied the most common SKF bearing types. Now click on each bearing picture to repeat the most important characteristics of each type. If you want to read more about SKF bearings, enter the SKF Interactive Engineering Catalogue on line at .Module 3: DesignationsIntroductionSKF bearing designations describe a bearing’s or component’s type, design, and variants. The designation can be found both on the box and on the bearing itself.Basic designations: Page 1A bearing designation for metric size bearings can either consist of a basic designation alone or a basic designation plus one or more supplementary designations, called prefixes and suffixes.The basic designation identifies the product type and size, while the supplementary designations identify design, special variants and bearing components.Basic designations: Page 2Each SKF bearing of standard metric design is given a basic designation, which normally consists of three, four or five figures.Basic designations: Page 3For example, the basic designation 22206 denotes a spherical roller bearing with the width series 2, diameter series 2 and a bore diameter of 30 mm.Supplementary designations: Page 1The supplementary designations consist of both prefixes and suffixes. Supplementary designations: Page 2Prefixes are used to identify component parts of a bearing and are usually followed by the designation of the complete bearing.Supplementary designations: Page 3Suffixes are used to identify designs, which differ in some way from the original design. The suffixes are divided into four main groups: Internal design, external design, cage design and variants, all of which are added to the basic designation in this order.End of course testNow it’s time to see what you learned.If you pass the test on-line then you’ll be able to print your course completion certificate.。

有关电子海图航线设计的一些认识

有关电子海图航线设计的一些认识

有关电子海图航线设计的一些认识作者:和新占来源:《珠江水运》2019年第07期摘要:本文讲述了电子海图(TOKYO KEIKI)的海图选取,航线设计及领海基线、低硫油区域、报告线的绘制。

关键词:海图航线设计由于电子海图的普及和使用,二副的航线设计也由传统的手写笔画变成了现在的鼠标键盘操作,中远海运船舶电子海图机器型号多为为TOKYO KEIKI EC-8000K/EC-8500K,下面是本人对电子海图航线设计的一些个人经验和大家分享。

1.航次海图的选取收到航次任务后,打开GATEWAY软件,在Catelogue界面内,左侧[Product Selection]界面选择 [AVCS Charts],通过点击[Route]-[New]大致画出计划航线,然后通过点击鼠标右键,弹出覆盖该点的所有海图,移动鼠标依次选取从始发港到目的港的最大比例尺海图。

后续操作在GATEWAY软件使用说明书均有说明,在次不再赘述。

下面是申请电子海图时的一些注意事项:(1)海图主管一般将电子海图Permit有效期设定为3个月,根据航次的长短的具体情况,申请海图,如果是长航线,如美洲航线,可分两段而分段申请,第一段从航次第一装货港至第一卸货港。

第二段从第二卸货港至航次结束港,在预抵第一卸货港10天前左右申请。

如果是短航线,可一次性申请航次全部海图。

一般情况下,应尽量减少申请海图的次数,其一是为了减少海图出错的概率,其二也可以减少工作负担。

(2)电子海图Permit的有效期是按整月计算的,而不是以申请的日期顺延3个月。

例如2018年9月28日申请电子海图Permit,则其有效期至2018年11月30日,而不是2018年12月28日。

所以应尽量避免在月底申请电子海图,长航线应特别注意。

(3)有些海区电子海图没有覆盖,特别是一些港口﹑海峡﹑运河,如智利港口HUASCO,查英版Catelogue NP131,港口区域有大比例尺纸质港图覆盖,而电子海图没有覆盖。

Key to ExercisesOpenerSuggested answers for reference:1。

In China it is a familiar scene that grandparents take their grandchildren to or from school every day, which, however,seldom happens in the West. There parenting responsibility mainly rests with the parents rather than others。

2。

In general there is not much difference between Western and Chinese tourists。

If any, it seems that Chinese like to pose for photos with the scenery as the background,whereas Westerners often just shoot pictures of scenic spots。

3. Well,it’s true that many Western employees see them and their boss as equals, but anywhere,anytime,you and your boss are never equals in its truest sense. There always exists a gap in between. Compared with Westerners, Chinese employees might tend to be more forbearing (克制) towards their boss and seldom air their grievances publicly.Reading & InteractingI。

Report any damage immediately to your local authorized distributor. Please save the shipping con-tainer for damage inspection or future transportation.Incorrect handling of the positioner may adversely affect the performance of the unit in its application. Stand-ard handling and lifting practices should be employed, product may be heavy.Please observe the following guidelines for handling and mounting of your new positioner.DO NOT allow the positioner to drop onto the mounting surface. Dropping the positioner can generate im-pact loads that may result in flat spots on bearing surfaces or misalignment of drive components.DO NOT drill holes into the positioner. Drilling holes into the positioner can generate particles and machin-ing forces that may effect the operation of the positioner. Parker will drill holes if necessary; contact your local authorized distributor.DO NOT subject the unit to impact loads such as hammering, riveting, etc. Impacts loads generated byhammering or riveting may result in flat spots on bearing surfaces or misalignment of drive compo-nents.DO NOT lift the positioner by cables or cable management system. Lifting positioner by cables or cablemanagement system may effect electrical connections and/or cable management assembly. The unit should be lifted by the base structure only.DO NOT expose positioner to mist, spray or submersion in liquids.DO NOT disassemble positioner. Unauthorized adjustments may alter the positioner ’s specifications andvoid the product warranty.Thank you for your interest in the Light Capacity Rodless (LCR) series miniature actuators. The LCR is designed for maximum flexibility to deliver the most value for the customer. The LCR is ideal for Maldiplate, Titer tray, and slide automation , as well as any light weight payload. The “off the shelf ” product will significantly reduce design , procurement, inspection, and handling time; in turn bringing your product to market faster. The following user guide will direct you in any needed maintenance items and basic features of the LCR series. If you have any questions or challenges please call our factory support team at 800-245-6903.Return InformationReturnsAll returns must reference a “R eturn M aterial A uthorization” (RMA) number. Please call your local author-ized distributor or Parker Customer Service Department at 800-245-6903 to obtain a “RMA” number. Repair InformationOut-of-Warranty RepairOur Customer Service Department repairs Out-of-Warranty products. All returns must reference a “RMA”number. Please call your local authorized distributor or Parker Customer Service Department at 800-245-6903 to obtain a “RMA” number. You will be notified of any cost prior to making the repair. Warnings and PrecautionsHot SurfacesDO NOT touch rotary motor coils located on the MX45S after high duty operation. Motortemperature may approach 60°C. The unit itself may become warm or hot to the touch.Electrical ShockDO NOT take apart or touch any internal components of the positioner while unit is pluggedinto an electrical outlet. SHUT OFF power before replacing components to avoid electricalshock.Pinch PointsUnit may have a pinch point because the top extends over the base of the table. Proper careshould be exercised.Vertical OperationDepending upon your load and screw selection the carriage and load may ‘backdrive’ in pow-er loss situations potentially causing product damage or personal injury.General SafetySometimes positioners move without warning, keep all personnel away from dynamic travelrange of positioner.Strain Relieve Electrical ComponentsAll electrical components (such as motor, encoders and limit/home switches) must be strainrelieved. Failure to strain relieve electrical wires or cables may result in component failureand/or possible personal injury.High Magnetic FieldUnit may be HAZARDOUS to people with Pace Makers or any other ‘magnetically-sensitive’medical devices. Unit may have an effect on ‘magnetically-sensitive’ applications.Moving CablesIf the LCR cables are to be moving, the use of high flex cabling to insure long life isrecommended.Specification ConditionsSpecifications Are Temperature DependentCatalog specifications are obtained and measured at 20 Degrees C. Specifications at any othertemperature may deviate from catalog specifications. Minimum to maximum continuous operatingtemperature range (with NO guarantee of any specification except motion) of a standard unit beforefailure is 5 - 40 degrees C.Specifications Are Mounting Surface DependentCatalog specifications are obtained and measured when the positioner is fully supported, bolteddown, and is mounted to a work surface that has a maximum flatness error of:0.001mm/300mm (0.00004”/ft)Table will operate with work surface of 0.100mm/300mm flatness or worse, but performance speci-fications will be significantly effected.Specifications Are Point of Measurement DependentCatalog specifications and specifications in this manual are measured from the center of the car-riage, 38 mm above the carriage surface. All measurements taken at any other location may devi-ate from these values.Specifications Are Load Mounting DependentCatalog specifications are obtained and measured when the customer load is fixed to the carriagemounting surface(s) and has a flatness of equal to or less than 0.0025mm (0.0001”). The table willoperate with customer load surface greater than 0.0025mm (0.0001”) flatness, but performancespecifications will be significantly effected.P2 DRIVEChapter 2 - LCR Specifications LCR–How to OrderLCR22/LCR30 SERIES PRODUCT MANUAL__________________Dimensional Drawings– LCR22 Leadscrew DriveDimensional Drawings–LCR30 Leadscrew DriveDimensional Drawing– LCR22 Belt DriveDimensional Drawings–LCR30 Belt DrivePerformance Specifications–LCR Screw Driven• Moment loading : Moment ratings are reduced ,when multiple moments/forces are applied , see page 26.LCR Screw -Driven SpecificationsLinear Speed Versus Thrust GraphsPerformance Graph Notes:To simplify application, the different aspects of positioner performance including motor torque, motor speed, screw efficiency, friction, safety margin, etc. have been consolidated into these speed versus thrust graphs.

When fastening to load take precaution in using screws with no more than 5.5mm of thread engagement, as to not damage positioner.The LCR30 contains 2.5 diameter H7 (slip fit) dowel holes for repeatable mounting to customer load plate if desired.See pages 10 thru 13 for detailed carriage specifications.WARNING : To avoid damage to nut-carriage assemblyDo not back drive (push by hand) the carriage. Carriage should be only moved by input to thedrive shaft via motor or hand crank.Moment loading pre-cautions :The LCR positioners have rated individual moment and load ratings. When multiplemoments are applied to carriage these rating must be reduced use the equation below as a guideline.Moment Factor:Take each existing moment/ corresponding maximum allowable moment = moment factor.Sum all the moment factors and result must be less than 1.8Example : LCR30 screw drive sq rail version with the following:Mroll =0.5 N-m = 0/2.6 (0.00)Mpitch =2.5 N-m = 2.5/8.2 (0.30)Myaw =1.0 N-m =1.0/6.5 (0.15)SUM THE ABOVE=(0.00+0.30+0.15)=0.45 WHICH IS LESS THAN 1.8Moment loading is acceptable.Limit/Home Switch Mounting/AdjustmentTravel limit sensors signal the motor to stop whenever the carriage is approaching end of travel. The home sensor provides a fixed reference point to which the carriage can be commanded to return repeatedly.If equipped the LCR limit home switches are installed at factory but not set. To adjust the switches . Loosen the flat head screw by turning (CCW) and position the switch to desired location and then retighten.Insert the switch into c-slot ( screw head facing up and then rotate 90’) and mountThe limit switches must be inserted into the top c-slot for the magnet in carriage to trigger.The limit switches can be mounted to either side of unitSee page 22 for detailed switch specificationsChapter 5–Maintenance and Repair LubricationNo lubrication is required in standard operating conditions.LCR BELT DRIVE INFORMATION:Mounting Motor to LCR22 belt drivesMount motor to motor block by inserting the motor /motor shaft into input shaft of table.
