汽车万向节十字轴形位公差直接影响主机的传动效率及任意方向摆动 ,因此控制十字轴的形位公差非常重要 ,下面就其测量方法进行探讨。1　轴颈圆柱度的测量采用比较测量法的机械式仪器测量原理见图1。将十字轴放在两个等高的Ｖ型角铁上 ,指示表指在支承夹对侧 ,旋转一周以上 ,测? Automotive universal joint cross shaft form bit tolerance directly affects the host drive efficiency and arbitrary direction of the swing, so the control of the cross-shaped form of position tolerance is very important, the following discussion of its measurement methods. 1 journal cylindricity measurement using comparative measurement of mechanical instruments measuring principle shown in Figure 1. Place the cross shaft on two contoured V-shaped angle irons, indicating that the watch is on the opposite side of the support clip and rotate for more than a week.
