基于接触强度的直动滚子凸轮基本尺寸设计

Method of Designing Basic Size of Moving Roller Plate Cam based on Contact Strength

对Hertz接触理论下的直动滚子从动件盘形凸轮的接触应力计算公式进行分析,通过对公式中凸轮综合曲率半径、从动件滚子接触线长度和凸轮许用压力角的确定方法进行讨论,得到根据凸轮接触强度进行直动滚子凸轮基本尺寸设计的方法。

The contact stress calculation of the plate cam mechanism with translating roller-moving follower based of the Hertz contact theory is studied.The methods what are used to calculate the synthesis curvature radius of cam,contact line length of follower roller and allowed pressure angle of cam are discussed.It's achieved that the method of designing the basic parameter of the moving roller plate cam according to contact strength.
