To be able to make a statement as to the service life of the guide, the graph below plots the load comparison factor fv against the service life.These values are only theoretical. You must consult your local Festo contact for a load comparison factor fv greater than 1.Load comparison factor f v as a function of service life lExample:A user wants to move an X kg load. Using the formula (a page8) gives avalue of 1.5 for the load comparison factor fv . According to the graph, the guide would have a service life of approx. 1500 km. Reducing the acceleration reduces the Mz and My values. A load comparison factor f v of 1 now gives a service life of5000 km.Comparison of the characteristic load values for 5000 km with dynamic forces and torques of recirculating ball bearing guides The characteristic load values of bearing guides are standardised to ISO and JIS using dynamic and static forces and torques. These forces and torques are based on an expected service life of the guide system of 100 km according to ISO or 50 km according to JIS.As the characteristic load values are dependent on the service life, the maximum permissible forces and torques for a 5000 km service life cannot be compared with the dynamic forces and torques of bearing guides to ISO/JIS.To make it easier to compare the guide capacity of guide axes ELFC with bearing guides, the table below lists the theoretically permissible forces and torques for a calculated service life of 100 km. This corresponds to the dynamic forces and torques to ISO.These 100 km values have been calculated mathematically and are only to be used for comparing with dynamic forces and torques to ISO. The drives must notbe loaded with these characteristic values as this could damage the axes.10d I nternet: /catalogue/...Subject to change – 2022/10Guide axes ELFC, without driveData sheet2nd moment of areaMaximum permissible support spacing L (without profile mounting) as a function of force F In order to limit deflection in the case of large strokes, the axis may need to be supported.The following graphs can be used to determine the maximum permissible support spacing L as a function of force F acting on the axis.

M A G N E T I C SGuide to Inductors: Basics of InductorsTRIAD MAGNETICS’ BASICS OF INDUCTORSInductors are used to store energy, create impedance, and modulate the flow of current. There are many types of inductors, as well as many core and winding styles, suited to different circuits. Inductors resist changes in currents through their windings — that is, they try to make any changing current more stable. They limit current increases by converting energy from the increasing current into a magnetic field. As the current decreases, energy that is stored in the magnetic field is converted back into the current; this is then added back into the decreasing current in order to prevent it from dropping as quickly. The current is then changed by the voltage across the inductor. This voltage can oppose the source to convert current into the magnetic field, or the voltage can add to the source to convert magnetic field energy into current.Inductance is measured in henries. One henry is defined as the inductance that creates one volt across the inductor when the current is changing at a rate of one ampere per second.Power inductors are typically used to smooth the flow of current. When current is always flowingin one direction (but varies in magnitude), power inductors reduce the value of current peaks by converting the increase in current into magnetic energy, then releasing this energy back into electrical current when the current magnitude is reduced. In this way, they smooth the current by reducing the peak current and increasing the minimum current.The energy stored in the inductor can be calculated by:Joules = ½ * Inductance (in henries) * Current squared (in amperes)This holds true as long as the inductance value remains as expected.Inductors also create near lossless impedance. This enables them to be used as filters, allowing lower frequencies to see smaller impedances and higher frequencies to see higher impedances.Core Materials and ShapesDepending on circuit type and power requirements, there are many choices for core materials and even more options for core shape and size.Core materials include silicon steel, powdered iron or nickel, other alloys, ferrites, and even air. Each material has its own magnetic properties: how much energy can be stored, how much inductance the core can create, how much energy will be lost (due to hysteresis and eddy current losses), and how stable these factors are with changing temperatures, currents, and frequencies.Core shapes include stamped laminations, “C” cores (strip-wound rectangular cores), toroids (donut or annulus), and many ferrite shapes: U, E, planar, pot, etc. Depending on the construction of the coil around it, each shape has various benefits and drawbacks.The proper choice of core material and shape will createan inductor that best meets the needs of the customer:electrical performance, size, shape, cost, etc.When comparing energy storage to core weight andvolume, toroidal cores are a near-perfect core shape;every portion of the core is used to wind upon, and everyportion of the core can be covered by the winding.The magnetic field of a toroidal winding is confinedalmost completely to the physical space of the winding,which means that the majority of the lines of force arefound within the form of the toroidal core.Flux density of a toroid is essentially uniform throughout the entire electromagnetic path. Permeability, given a particular set of conditions, is effectively constant. Externally originating magnetic fields have little to no effect on toroid-constructed cores.However, there are disadvantages to toroidal cores — primarily cost. Some of the more effective materials used in toroidal cores are more expensive than standard materials.Winding is another source of cost increase. Toroidal cores are not adaptable to multiple windings — the process of simultaneously winding more than one coil — thereby increasing production costs. Another restriction is the size of the wire, as winding machines used for toroidal wiring have difficulty handling the finer wires often used.The windings of a toroid coil can be trimmed at the bridge to achieve very precise, close-tolerance inductance values. Because of their adaptability to shaft mounting, inductors with toroidal cores can also be easily stacked in banks. Shielding between stacked toroidal coils is only required in unique cases.Toroidal inductors largely feature powdered metal cores. These inductors, known as differential mode inductors, feature greater energy storage properties than inductors with other high-frequency core materials. Additionally, their toroidal construction leads to controlled magnetic fields with minimal stray fields.Toroidal inductors made with ferrite are known as common mode inductors and function slightly differently than differential mode inductors. Always constructed with two or more separate and identical windings, common mode toroidal inductors filter signals common to both power lines. Differential currents cancel themselves out in toroidal inductors, which leads to very high common mode signal inductance without the need to store the power line frequency energy.Inductor ApplicationsThe range of applications for inductors is quite varied.Common mode inductors are often utilized in applications that use higher frequencies, known as switched mode applications. Common mode toroidal inductors are most effective at reducing signals from the switched mode circuitry frequencies as well as their harmonics at even higher frequencies. They remain effective at ranges surpassing 10 MHz and reduce electromagnetic interference from offending frequencies.When combined with other components, such as resistors, inductors become important aspects of phase-sifting and phase-adjusting devices. They are also commonly used as complex loading devices and transient suppressing chokes for voltage surge protection.Toroidal inductors’ small size and low weight make them ideal for a number of high-performancebut space-sensitive applications — in the aerospace industry, for instance. The toroidal core shape maximizes the use of the core and minimizes winding resistance.Differential mode inductors are intended to smooth the flow of current by storing and releasingthat stored energy to smooth out the peaks and valleys of current flow. These inductors can store significant amounts of energy and work from DC through very high frequencies. Considerations for Inductor DesignAside from intended end use, there are a number of important factors to take into account when designing or specifying an inductor: core material, wire and winding, and packaging.Core MaterialThe selection of a core material is very important, as some materials can store very large energies at DC or low frequencies but have high losses at high frequencies. Core materials that have low losses at high frequencies tend to not be able to store as much energy. The best material selection depends greatly on the circuit requirements.The many different core materials used in inductors can be generally categorized as solid magnetic metallic, powder and ceramic, and sometimes even air.Iron cores for inductors are manufactured either from a strip or tape of sheet steel that is wrapped around itself, washer-like preforms that are stacked atop each other, or stamped shapes. Many magnetic metallic alloys are sensitive to pressure (especially nickel alloys), so they must be cushioned and handled gently.Powder cores are blends of powdered metals that are annealed, pressed, and sintered into their final core shape. Powdered metals commonly used for inductor cores include molybdenum permalloy, a nickel-iron-molybdenum blend, carbonyl iron, and various ferrite blends.A primary benefit of powdered metal cores — particularly molybdenum permalloy cores — over solid cores is that they contain a uniform distribution of air gaps due to the granular nature of the raw material. This leads to fairly constant permeability and a fairly constant core loss in a wide varietyof use scenarios. Powdered ferrite cores can achieve high electrical resistance and low eddy current losses.Powdered metal can also be altered by adding additional metal powders to the mix in order to achieve special core properties, such as extremely stable temperature characteristics.Wire and WindingAbove all else, the wire and winding of your inductor is its most important component. When choosing wire for your winding, you must consider wire material, width, coating or insulation material, and winding method.Round copper wire is by far the most commonly used for inductor winding, though other options include copper or aluminum in sheet, square, or rectangular sizes. Litz wire — a specialty wire made of numerous individual strands twisted or braided together — is also an option.Wire coating can have a significant impact on the manufacturing and functioning of an inductor. Nyleze is a solderable coating with high-abrasion resistance — which is important during the winding process — that can operate in conditions as hot as 155 degrees Celsius (266 degrees Fahrenheit). Thermaleze is also abrasion resistant and can withstand temperatures up to 200 degrees Celsius (392 degrees Fahrenheit), but it cannot be directly soldered. PTFE-insulated wire (frequently recognized as Teflon-insulated wire) can help an inductor maintain low winding capacitance. These are only a small sampling of available wire coatings. Your specific needs will determine the best option.For medium- and high-frequency applications, distribution of capacitance throughout the coil must be considered. Therefore, the winding methods that counter it — such as the bank and progressive methods in toroidal windings or single layer in bobbin windings — should be used. Foil windings can have significant capacitance from turn to turn.Losses within the winding are the result of heat caused by current passing through the winding resistance. At low frequencies, this is generally just W = I^2 * R, where the R equals the DC resistance. But at high frequencies, the effective resistance can be tens or hundreds of times greater due to skin effects and proximity effects. The number of winding layers and conductor size are the major factors in how much higher the effective AC resistance is compared to the DC resistance; fewer layers and smaller conductor size reduce the AC resistance at high frequencies. Choosing the correct winding method and conductor(s) is paramount in designing a high-current, high-frequency inductor that operates as intended.PackagingAn inductor’s packaging is not the material in which it is shipped but rather the material in which it is sealed. Packaging can be categorized as open, no packaging, molded, or metal-encased.Open coils are generally comprised of the winding, core, and plastic-insulated termination leads. Open coils derive most of their protection from their impregnation. They can also be sealedwith plastic, but this is for mechanical protection against scraping or breakage as opposed to environmental protection.For an inductor to be properly environmentally protected, it must be molded in such a way as tobe fully encapsulated or hermetically sealed and possibly encased in a metal housing. Moldedcoils are fully encapsulated in a material such as thermoplastic, various thermoset compounds, or varnish. Metal-encased coils are the most secure and can most easily have electrostatic and magnetic shielding added.Learn More from TriadInductors are a complex component with dozens of variables to choose from, which makes them a difficult product to select or specify correctly.

工程机械引导轮的铸改锻设计
工程机械引导轮的铸改锻设计摘要本次设计首先是对工程机械底盘件引导轮的改革,此前,引导轮是铸钢式结构,此次设计为锻造式结构,主要目的是为了避免铸钢引导轮在使用时因铸造缺陷而导致的失效,我们知道,铸钢引导轮较早前是市场上通用结构产品,已经在市场上流行多年,铸钢引导轮也得到了很多主机厂的认可,但是铸钢引导轮有明显的缺陷,因为是铸造结构,铸造是无法避免疏松、砂眼、气孔等明显的铸造缺陷的,这些缺陷一旦产品,也是不可逆的,会造成主机在短期内,因为这种问题的发生而导致停机,在此种情况下,锻造引导轮应运而生,锻造引导轮的设计,从实际应用上出发,设计初衷使引导轮的使用寿命得到了大大提升,也使得主机的故障率有明显的降低,此种工艺升级,不仅得到了市场认可,也很快就占领了主机的大部分市场,提高了市场占有率,而因为锻造引导轮的流行,不仅使加工工艺得到了优化,也完美的降低了生产成本,不仅从供货商,再到主机厂,都降低了生产成本,因此,随着市场认可度的扩大,相信在不久的将来,会有越来越多主机做出选择。
关键词: 锻造引导轮,工艺升级,市场占有率,降低故障率I第一章前言第一章前言目前引导轮在市场上主要分铸造引导轮和锻造引导轮,开发锻造引导轮的主要目的就是为了淘汰铸造引导轮,相对于铸造引导轮,锻造引导轮避免了铸造引导轮的所有缺陷、质量问题,而随着锻造引导轮的开发,前期也经历了很多实验。
我司自开始自行研制锻造引导轮以取代传统的铸造引导轮,锻造相对于铸造的好处众所周知,对主机厂对整机减重而不减强度有很大帮助,在研发过程中我司不断的克服各种问题,最终基本达到主机厂的要求,能够满足客户的需求。
设计初期考虑模锻毛坯进行锻造,首先根据毛坯简图进行模具设计,开完模具后,在模锻过程中考虑到,易造成引导轮锻造缺陷的情况,避免产品报废,要提前进行分析。
经过长时间的锻造验证,最后按照合理的锻造工艺进行安排生产,采用油压机制坯,压扁冲孔一次性完成,基本保证冲孔的精度问题,杜绝了上下重头不同心的问题;油压机制坯过程中厚度通过限位开关控制,基本能够保证制坯厚度一致,油压机制坯操作过程只需要操作工1人控制,减少人员配备,大大的降低了人工成本。

The point of application of force is the point where the centre of the guide and the longi-tudinal centre of the slide intersect.These values must not be exceeded during dynamic operation. Special at-tention must be paid to the decelera-tion phase.If the axis is subjected to two or more of the indicated forces and torques si-multaneously, the following equation must be satisfied in addition to the indicated maximum loads:Calculating the load comparison factor:F 1/M 1 = dynamic value F 2/M 2= maximum valueService lifeThe service life of the guide depends on the load. To provide a rough indication of the service life of the guide, the graph below plots the load comparison factor f v against the service life.These values are only theoretical.

一、设计任务
引导轮安装在履带上,用来引导履带。
已知液压挖掘机履带节距为135mm(见表一),参考中华人民共和国机械行业标准JB/T 2983.2-2001(履带式推土机引导轮行业标准),分析标准中给出的图,得知引导轮主要包括引导轮轴,轴套,铁套,轮体,堵板以及一些标准件,参考此图,并参考相关标准,设计出液压挖掘机的引导轮。
表一工程钻机质量与履带节距的关系
二、结构参数计算
根据履带的节距参考JB/T 2983.2-2001履带式推土机引导轮行业标准,其直径为488mm 。
其它安装尺寸与技术要求可参考该标准。
2-1、 驱动轮节圆D q

式中t ——履带节距

上式中t=135mm ,从而求得D t ≤108~135mm 。
2-5、 支重轮个数n

2Z
t A n +=
式中A ——轴距(10-3mm )。
为了减小摩擦损失,拖链轮的数目不宜过多,小挖掘机每侧拖链轮一般为1个;考虑到滚动阻力的大小和接地比压的均匀性,小挖掘
的每侧支重轮通常为4~5个,具体数目随机重的增加而增多。
三、性能参数计算
3-1、行驶速度V
V max =4.4km/h V min =2.4km/h (行驶速度参照SY75C-9) 3-2、.爬坡能力α
履带行走装置一个显著特点就是爬坡能大,一般为50%~80%。
初步确定爬坡能力后,可通过理论分析进行核算来选定。
挖掘机爬坡是需要克服下列几种阻力即: (1)、挖掘机自重在斜坡方向的分力
αsin G W p =
式中 G ——挖掘机的自重(N ); α——坡度角 。
(2)、.运行阻力
αcos 12.0G Wy =
(3).履带的内阻力
G W n 06.0=
则最大牵引力应不小于这些阻力之和,即
n y p W W W T ++≥
此外还应满足挖掘机在爬坡不打滑的条件,即 T G ≥α
ϕcos
式中ϕ——履带与地面的附着系数,见下表三。
表三 履带与地面的附着系数
从上表中选取06.0=ϕ,即松散土路;求挖掘机的最大爬坡能力
︒=20α
3-3、.接地比压p
履带式挖掘机的承载能力大小取决于机器运行的通过性和工作的稳定性。
若挖掘机的两条履带与土壤表面完全解触,并且挖掘机重心近似地位于支承面中心,则有:
bL
mg
p 2=
或
)
25.0(2o h l b mg p +=
式中 p ——履带平均接地比压(Pa ); m ——挖掘机工作质量(kg );
g ——重力加速度(m/s 2
); L ——履带接地长度(m ); b ——履带宽度(m )
; o h ——履带高度(m )。
平均接地比压是履带式液压挖掘机的一个重要指标,可以用来与同类型号产品作比较,主要根据地面条件、外形尺寸等进行合理选取。
在设计挖掘机时,在结构允许的范围内,尽量取小值;结合上面公式其中 L=2195mm (参照SY75C-9);b=400mm ,即可得出接地比压
p =33.485×103
Pa.
3-4、.最大牵引力T
履带行走装置的牵引力必须大于或等于个阻力之和,小于或等于履带对地面的附着力,一般情况下,履带行走装置爬坡不与转弯同时进行,只考虑挖掘机在最大设计爬坡能力的情况下确定的最大牵引力,不再考虑转弯阻力,而且行驶速度低,运行空气阻力忽略不计,则履带行走装置的最大牵引路T 计算公式为:
G fG T T T t f αsin +=+=
式中 T f ——履带行走装置的滚动阻力; T t ——履带行走装置坡道阻力;
f ——履带行走装置的滚动阻力系数,见下表; α——最大设计坡度角; G ——为整机重力。
表三 滚动阻力系数f
根据此式可以得出最大牵引力T =25990N.
四、引导轮结构设计
引导轮主要由引导轮轴、引导轮堵板、引导轮轮体和一些标准件(铁套、圆柱销、双金属轴套、螺栓弹簧、垫片浮动、油封浮油环、O形密封圈)组合而成,起作用主要是引导履带正确的卷绕,同时利用张紧装置使引导轮移动以调整履带的张紧度,所以引导轮既是履带的引导轮,有事张紧装置中的张紧轮。
下面将主要介绍引导轮轴、引导轮堵板、引导轮轮体的设计。
4.1、引导轮轴设计
图1 引导轮轴
根据JB/T 2983.2-2001,履带节距为135mm的引导轮轴总长为336mm,由于引导轮是对称的,轴的外形结构也可采用全对称式的结构,轴正中间处轴肩用来定位两个轴套,其结构及尺寸数据如图1,轴中间的孔道用于储存润滑油,润滑油从轴左端注入,从轴上另两个出口流出,达到润滑各界面效果。
注油后,左端用一个M12×1.5的螺塞密封,防止漏油。
轴上直径为45的两端轴段上分别有一个3×3
的小槽,是用来安装两个密封圈,防止油的泄露。
4.2、轮体设计
参考市面上的引导轮轮,一般有蜂孔式和箱体式两种(见图2及图3),箱体式的断面成箱型,由钢板焊接制成,蜂孔式轮体的轮缘和箱体式的一样,也是用钢板焊接制成,不同之处是中间用一块较厚的带蜂孔的钢板代替了箱体结构,蜂孔式较箱体式能节约材料,制造时也相对简单,因此我选用了蜂孔式轮体,轮体上设计了六个均匀分布的直径为60mm的蜂孔,中间钢板厚度为40mm,能满足强度要求。
轮体的其余设计相对简单,其外径为488mm,内径参考JB/T 2983.2-2001及铁套外径,为76mm,其余结构及尺寸设计的标准是能满足使用要求,容易制造,尽量节省材料,外形美观大方。
轮体上有四个螺纹孔,与M8×60的螺栓相连。
此外,轮缘表面需经高频淬火,HCR﹦52~60。
其具体结构尺寸见图4。

4.3、引导轮堵板设计
堵板用来防止外界的杂物进入引导轮体内部。
堵板的设计主要要要考虑引导轮结构的完整性,合理性,设计时要避免其在结构上与轮体等零件互相干涉,尽量要设计的美观,容易制造,节省材料。
堵板结构尺寸见图5,其与铁套,轮体用4个螺栓连接,其安装浮封环处的结构尺寸设计和铁套处的相同.

4.4、引导轮装配图设计
把个零件装配到一起,加入标准件,完成设计,引导轮的装配简图见图6。
根据JB/T 2983.2-2001中表5,在外观与装配质量上有几点要求,详见下表:

五、设计小结
这次关于液压挖掘机履带引导轮的设计是我真正理论联系实际,深入了解设计概念和设计过程的实践考验,对于提高我机械设计的综合素质大有用处。
通过这次设计实践,使我对机械设计有了更多的了解和认识,为我以后的工作打下了坚实的基础。
设计中我得到老师以及学长的细心帮助和支持,衷心的感谢他们的指导与帮助,
在设计中还存在不少错误和缺点,需要继续学习有关机械设计的知识,从而提高自己设计和实践操作能力。
