自动脱档是变速箱的主要故障之一。为了解决这个问题,我厂生产的EQ-153八吨载重汽车变速箱四五档滑动齿套接合齿,采用了广泛使用的防脱档结构,即接合齿面设计成7°收缩齿,这样,在传动过程中齿面产生的轴向力就能有效地阻止脱档。因直齿与收缩齿间无空刀槽(见图1),无法用插齿法进行加工,故采取了胀挤加工的新方法。胀挤加工内收缩齿的原理(见图2),是用一个可
Automatic gear-off is one of the main fault gearbox. In order to solve this problem, I plant the EQ-153 eight tons of truck transmission sliding gear box gear fourth gear, using a widely used anti-off-file structure, that is, the engagement tooth surface designed to shrink tooth 7 °, In the transmission process, the axial force generated by the tooth surface can effectively prevent the gear. Due to no teeth between the straight teeth and contraction of the groove (see Figure 1), can not use the gear method for processing, it took a new method of expansion extrusion processing. Expansion squeeze tooth processing within the principle (see Figure 2), is to use a can
