液压传动中的快慢开关一般都是有偏心的,过去我们是根据外圆的不同和偏心距的大小各设计一个偏心夹具,这样不但浪费人力物力,而且、使用也不方便。后来又改用偏心套,但是还没全部解决问题。 目前,我们设计并使用了一种车偏心的万能夹具(如图1)这种夹具结构很简单,而且不论外圆 The speed switch in the hydraulic transmission is generally eccentric. In the past, we designed an eccentric jig according to the difference of the outer circle and eccentricity, which not only wastes human and material resources, but also is inconvenient to use. Then use eccentric sets, but not all solve the problem. At present, we design and use a car eccentric universal fixture (Figure 1) This fixture structure is very simple, and regardless of the outer circle
