目前冶金系统大量使用的138型太脱拉汽车,中、后桥减速器驱动轴前端和前桥后端丝扣固定帽,在使用中经常发生松动和脱落现象,引起轴上传动齿轮相对位置变化,使差速器齿轮、减速器齿轮及摆动轴发生严重破坏。 为减轻固定帽所受轴向推力,可将原中心齿轮毂切去15毫米厚,再开两个宽10毫米深5.5毫米的槽,位置如图1。 另作一锁止环,形状尺寸如图2。锁止环上有 At present, the metallurgy system is widely used in 138 type too pull off the car, in the rear axle drive shaft front axle and the front end of the threaded fasteners hat, often in use, loose and fall off, causing the relative position of the shaft drive gear changes , So that differential gear, gear reducer and the swing axis serious damage. In order to reduce the axial thrust of the fixed cap, the original central gear hub can be cut off to a thickness of 15 mm and then two grooves 10 mm wide and 5.5 mm deep are also provided. The position is shown in FIG. 1. Another for a locking ring, shape and size shown in Figure 2. Lock ring there
