汽车变速箱的第二轴总成在试验过程中,为了解决噪音或同步器不良,需要更换齿轮。拆齿轮时,先要把固定齿座的锁环取下。锁环是用φ4mm弹簧钢丝卷成,弯钩部分又牢牢地插进止推环的花键槽内,用普通工具很难拆卸,甚至有时毁轴取环。为此,我厂设计了一种带花键齿的拉拔器。其拆卸操作过程是:首先把紧定螺钉3往外拧动,使花键拉爪1的两体往外胀开,然后放入需拆的花键轴上,
The second gear assembly of the automotive transmission During the test, in order to solve the noise or poor synchronizer, the gear needs to be changed. When disassembling the gear, first remove the lock ring of the fixed gear seat. The lock ring is made of φ4mm spring wire, the hook part is firmly inserted into the spline groove of the thrust ring, hard to disassemble with ordinary tools, and sometimes the shaft is destroyed. To this end, I plant a puller designed with spline teeth. The disassembly operation process is: firstly, tighten the set screw 3 outward so as to expand the two bodies of the spline claw 1 outwards and then put it into the spline shaft to be disassembled,
