Gear hobbing processing principle and process related description

Publication time: 2020-05-28 Website: https://ptogearboxes.com Edit: EP

The gear rolling processing principle and process related descriptions are as follows, for reference and understanding.

齿轮滚抛加工原理:

滚抛是把工件装在封闭容器内,借助于滚拋液的作用,在专用机床上,按照一定的规律运动,使gear的齿面粗糙度降低。

齿轮滚抛加工工艺:

1、第一类:淬火后→化抛→回火→滚抛

2、第二类:淬火后→串光→回火→滚抛

化学抛光液配方及抛光时间:

草酸13g/L,双氧水20mL/L,6021活性剂0.05g/L,抛光时间20左右。

滚抛液配方:

滚抛余量:

根据不同类型的齿形及模数大小,其滚抛余量也不同。下表是不同的齿形以及模数选用的抛光和滚抛余量。
