渐开线内齿轮成型磨削砂轮修整方法

Dressing Method of Form Grinding Wheel Used in Involute Internal Gear Grinding

成形法磨齿的关键因素是成型砂轮的修整。本文介绍了一种渐开线内齿轮成型磨削的砂轮修整方法。根据渐开线的形成原理,采用金刚轮作为修整工具,用数字控制方式完成修整运动。通过数控程序可实现对不同齿数和模数的任意参数渐开线齿形的修整。

Gear form grinding has many advantages over generating grinding. But the key factor of affecting the application of gear form grinding is the dressing technology of form grinding wheel.This paper introduces a new type of dressing technique of form grinding wheel used in internal gear form grinding.It is based on the generating principle of involute and the diamond wheel as dressing tool is used. Dressing motion is controlled by NC(numerical control) controller.By means of this technique, the dressing of involute profile with different teeth and modulus can be easily realized by modifying the NC program.
