实际上，几乎所有的机器中都装有轴。轴最常见的形状是圆形，其截面可以是实心的，也可以是空心的（空心轴可以减轻重量）。有时也采用矩形轴，例如，螺丝起子的头、套筒扳手和控制旋扭的杆。为了在传递转矩时不发生过载，轴应该具有适当的抗扭强度。轴还应该具有足够的抗扭刚度，以使同一个轴上的两个传动零件之间的相对转角不回过大。一般来说，在轴的长度等于其直径的20倍时，扭转角不应该超过1 度。轴安装在轴承中，通过齿轮、皮带轮、凸轮、和离合器等零件传递动力。通过这些零件传来的里可能会使轴产生弯曲变形。因此，轴应该有足够的刚度以防止支撑轴承受力过大。总而言之，在两个轴承支承之间，轴在每英尺长度上的弯曲变形不应该超过0.01 英寸。此外，轴还必须能承受弯矩和扭矩的组合作用。因此，要考虑扭矩与弯矩的当量载荷。因为扭矩和弯矩会产生交变应力，在许用应力中也应该有一个考虑疲劳现象的安全系数。直径小于3 英寸的轴可以采用含碳量大约为0.4%的冷轧钢，直径在3~5 英寸之间的轴可以采用冷轧钢或锻造毛坯。当直径大于5 英寸大，则要采用锻造毛坯，然后机械加工到所要求的尺寸。轻载时，广泛采用塑料轴。由于塑料是电的不良导体，在电器中用它做轴比较安全。齿轮和皮带轮等零件通过键联接在轴上。在对键及轴上与之相应的键槽进行设计时，必须进行认真的计算。例如，轴上的键槽会引起应力集中，由于键槽的存在使轴的横截面积间隙哦啊，会进一步减弱轴的强度。如果轴以临界速度转动，将会发生强烈的振动，可能会毁坏整台机器。知道这些临界速度的大小是很重要的，因为这样可以避开它。一般凭经验来说，工作速度与临界速度之间至少应该相差20%。 轴的设计工作的另一个重要方面是轴与轴之间的直接联接方法。这是有刚性或者弹性联轴器来实现的。联轴器是用来把两个相邻轴端联接起来的装置。在机械结构中，联轴器被用来实现相邻的两根转轴之间的半永久性联接。在机器的正常使用期间内，这种联接一般不必拆开，在这种意义上，可以说联轴器的联接是永久性的。但是在紧急情况下，或者需要更换以磨损的零件时，可以先把联轴器拆开，然后再联接上。联轴器有几种类型，它们的特性随其用途而定。如果制造工厂中或者船舶的螺旋浆需要一根特别长的轴，可以采用分段的方式将其制造出来，然后采用刚性联轴器将各段联接起来。一种常用的联轴器是由两个配对的法兰（盘）组成，这两个法兰盘借助靠键传动的轴套联接到相邻两节轴的两端，然后用螺栓穿过法兰联接起来形成刚性接头。相互联接的两根轴通常是靠法兰面的槽口来对准的。在把属于不同的设备（例如一个个电动机和一个变速箱）的轴联接起来的时候，要把这些轴精确地对准是比较困难的，此时可以采用弹性联轴器。这种联轴器联接轴的方式可以把由于被联接的轴之间的轴线不重合所造成的有害影响减少到最低程度。弹性联轴器也允许被联接的轴在它们各自的载荷系统作用下产生偏斜或在轴线方向自由移动（浮动）而不至于相互干扰。弹性联轴器也可以用来减轻从一根轴传到另一根轴上的冲击载荷和振动的强度。 而几乎所有的轴都装有滚动轴承。对于球轴承和滚子轴承，一个机器设计人员应该考虑下面五个方面：（a）寿命与载荷的关系；（b）刚度，也就是在载荷作用下的变形；（c）摩擦；（d）磨损；（e）噪音。对于中等载荷和转速，根据额定负荷选择一个标准轴承，通常都可以保证其具有令人满意的工作性能。当载荷较大时，轴承零件的变形，尽管它通常小于轴和其他与轴承一起工作的零部件的变形，将会变得重要起来。在转速高的场合需要有专门的冷却装置，而这可能会增大摩擦阻力。磨损主要是由于污染物的进入引起的，必须选用密封装置以防止周围环境的不良影响。因为大批量生产这种方式决定了球轴承和滚子轴承不但质量高，而且价格低，因而机器设计人员的任务是选择而不是设计轴承。滚动接触轴承通常是采用硬度大约900HV、整体淬火的钢来制造的。但在许多机构上不使用专门的套圈，而将相互作用的表面淬硬到大约600HV。滚动轴承由于在工作中会产生高的应力，其主要失效形式是金属疲劳，这一点并不奇怪，目前正在进行大量的工作以求改进这种轴承的可靠性。轴承设计可以基于能够被人们所接受的寿命值来进行。在轴承行业中，通常将轴承的承载能

轴承的摩擦与润滑外文翻译

本科生毕业设计专业外文翻译原文：Friction , Lubrication of Bearing 译文：轴承的摩擦与润滑 指导教师：王君莉职称：研究生 学生姓名：虞启志学号： 1102130221 专业：机械设计制造及其自动化 院（系）：机电工程学院 2015年4月10日

Friction,Lubrication of Bearing In many of the problem thus far , the student has been asked to disregard or neglect friction . Actually , friction is present to some degree whenever two parts are in contact and move on each other. The term friction refers to the resistance of two or more parts to movement. Friction is harmful or valuable depending upon where it occurs. friction is necessary for fastening devices such as screws and rivets which depend upon friction to hold the fastener and the parts together. Belt drivers, brakes, and tires are additional applications where friction is necessary. The friction of moving parts in a machine is harmful because it reduces the mechanical advantage of the device. The heat produced by friction is lost energy because no work takes place. Also , greater power is required to overcome the increased friction. Heat is destructive in that it causes expansion. Expansion may cause a bearing or sliding surface to fit tighter. If a great enough pressure builds up because made from low temperature materials may melt. There are three types of friction which must be overcome in moving parts: (1)starting, (2)sliding, and(3)rolling. Starting friction is the friction between two solids that tend to resist movement. When two parts are at a state of rest, the surface irregularities of both parts tend to interlock and form a wedging action. To produce motion in these parts, the wedge-shaped peaks and valleys of the stationary surfaces must be made to slide out and over each other. The rougher the two surfaces, the greater is starting friction resulting from their movement . Since there is usually no fixed pattern between the peaks and valleys of two mating parts, the irregularities do not interlock once the parts are in motion but slide over each other. The friction of the two surfaces is known as sliding friction. As shown in figure ,starting friction is always greater than sliding friction . Rolling friction occurs when roller devces are subjected to tremendous stress which cause the parts to change shape or deform. Under these conditions, the material in front of a roller tends to pile up and forces the object to roll slightly uphill. This changing of shape , known as deformation, causes a movement of molecules. As a result ,heat is produced from the added energy required to keep the parts turning and overcome friction. The friction caused by the wedging action of surface irregularities can be overcome partly by the precision machining of the surfaces. However, even these smooth surfaces may require the use of a substance between them to reduce the friction still more. This substance is usually a lubricant which provides a fine, thin oil film. The film keeps the surfaces apart and prevents the cohesive forces of the surfaces from coming in close contact and producing heat . Another way to reduce friction is to use different materials for the bearing surfaces and rotating parts. This explains why bronze bearings, soft alloys, and copper and tin iolite bearings are used with both soft

机械外文翻译---关于轴承和轴的相关知识

附录一 Knowledge On The Bearings and Shaft The bearings are fixed and reduce the load coefficient of friction in the process of mechanical transmission components. Can also say that when the other parts on the shaft relative motion, used to reduce the friction coefficient in the process of power transfer and fixed the mechanical parts to maintain the position of the shaft center. Bearings are important parts of modern machinery and equipment. Its main function is to support the mechanical rotating body to reduce the load coefficient of friction of the mechanical equipment in the transmission process. According to the different nature of friction of moving parts, bearings can be divided into two types of rolling bearings and plain bearings. Nano Lake, Italy, found a Roman vessel discovered early instance of ball bearings. The wooden ball bearings are used to support the rotating desktop. Ship construction in 40 BC. It is said that Leonardo da Vinci in the 1500 or so, a ball bearing through description. , There is a very important point is the ball collision, causing additional friction between the ball bearings of all kinds of immature factors. But can put the ball into a small cage to prevent this phenomenon. The 17th century, Galileo fixed ball ", or" cage ball "ball bearings did the earliest description. But then quite a long time, the bearings have been installed on the machine. The first patent on the ball channel the Carmarthen Philip Vaughan in 1794. In 1883, Friedrich Fischer proposed the idea of the use of suitable production machine grinding the same size, roundness accurate ball. This laid the foundation to create an independent bearing industry. In 1962, FAG the trademark has been modified and are still used today and become an integral part of the company in 1979. In 1895, Henry Timken designed the first tapered roller bearings, three years later obtained a patent and the establishment of the Timken Company. In 1907, SKF bearing factory Sven temperature Qwest designed the first modern self-aligning ball bearings. Study its role should be in terms of support, that the literal interpretation is used to bearing axis, but this is only part of its role in supporting its essence is to be able to bear the radial load. Can also be understood that it is used to a fixed axis. A fixed axis so that it can only achieve

外文翻译---轴、联轴器和滚动轴承

附录二外文原文和翻译 shafts、couplings and rolling contact bearings key words: shafts、couplings、bearings Virtually all machines contain shafts.The most common shape for shafts is circular and the cross section can be either solid or hollow (hollow shafts can result in weight savings ).Rectangular shafts are sometimes used ,as in screwdriver blades,socket wrenches and control knob stems . A shaft must have adequate torsional strength to transmit torque and not be overstressed. It also be torsionally stiff enough so that one mounted component does not deviate excessively from its original angular position relative to a second component mounted on the same shaft. Generally speaking ,the angle of twist should not exceed one degree in a shaft length equal to 20 diameters. Shafts are mounted inbearings and transmint power through such devices as gears, pullerys, cams and clutches. These devices introduce forces which attempt to bend the shaft; hence, the shaft must be rigid enough to prevent overloading of the supporting bearings. In general, the bending deflection of a shaft should not exceed 0.01 in. per ft of length between bearing supports. In addition, the shaft must be able to sustain a combination of bending and torsional loads. Thus an equivalent load must be considered
