、A sample installation of a rolling contact bearing is illustrated in Figure 3.2. The shaft and the bearing’s inner race rotate together, while the outer race and the transmission’s housing are stationary. When a shaft is supported in this way, the bearing’s outer race will fit tightly into a matching circular recess that is formed in the housing. As the shaft in Figure 3.2 turns and transmits power, the bearing could be subjected to forces directed either along the shaft (called a thrust force) or perpendicular to it (a radial force). An engineer will make a decision on the type of bearing to be used in a machine depending on whether thrust forces, radial forces, or some combination of the two act on the bearing. Thus, engineers apply the properties of force systems (as described in Chapter 4) when they analyze and select bearings and other machine components.

2、Helical gears are an alternative to spur gears; they offer the advantage of meshing more smoothly. Helical gears

1,抽样安装一个滚动接触轴承是说明了在图3.2 。轴和轴承的内圈旋转在一起,而外圈和传输的住房是固定的。当一个轴是支持这样一来,轴承的外圈,将配合严密,成为一个配套的通告休会,是形成于房屋。作为骨干,在图3.2之用,并传递功率,同时有可能会受到部队的指示,要么沿着轴(称为一个推力) ,或垂直于它(径向力) 。一个工程师将作出决定,对这类轴承被用来在一台机器要视乎是否推力,径向力,或者一些二者的结合行为,对轴承。因此,工程师运用性能的武力系统(章所述4 )当他们分析,并选择轴承和其他机械部件。

2 ,螺旋齿轮代替齿轮,他们提供的好处是啮合更为顺利。斜齿轮相似,其带动的对应在一定意义上的牙齿仍在形成圆柱形的,但在这种情况下,牙齿是不是水货,以齿轮的轴。反之,并作为其名称所暗示的,牙齿上的螺旋齿轮倾向于一个角度,使每一个齿结束对齿轮的圆筒形状的浅螺旋。单斜齿轮,是列于图3.25 。本着同样的目的有牙齿网格渐渐地,锥齿轮(见图3.24 ) ,同样可以形成螺旋而不是直的牙齿。

3 ,与那些想法,你可以看到你的条件,一台机器的组成部分失败,不仅取决于力量应用到它,而且它的尺寸和性能的材料,由它作出的。作为一个例子,在这破碎的曲轴显示,在图5.1是挽救组成一个单一的单缸内燃机。这个特别的失败是加速由急弯时说,已被削减,在轴的矩形键槽。螺旋形状的断裂面表明,该井已超负荷由一个高转矩之前,要打破。总之,工程师能够结合自己的知识的力量,材料,形状和尺寸,以便学习,从过去的失败,并更好地设计出新的硬件。
