对心滚子移动从动件盘形凸轮机构的接触应力

The Contact Stress of Plate Cam Mechanism with Translating Roller Moving Follower

当工作载荷较大时,凸轮表面和从动件端部的接触疲劳破坏就成为凸轮机构失效的主要形式之一。但在有关凸轮的教科书中,对接触应力的计算过程论述较少。本文详细分析了对心滚子移动从动件盘形凸轮机构接触应力的计算方法,并给出具体计算例题。

When the working load is large, the contact stress between cam surface and follower ends becomes the main cause of cam mechanism failure. But in the textbook about cam, the contact stress calculating process is seldom discussed. In this paper, the calculating method for the contact stress of plate cam mechanism with translating roller moving follower is presented, and some examples are given.
