鼓型滚子齿式空间凸轮机构凸轮曲面形成原理

The forming princinciple of spacial geared cam curved surface with drum roller follower

用回转变换张量法分析鼓型滚子齿式 (x向 )空间凸轮机构从动曲面与凸轮曲面在接触线位置的几何关系 ,建立凸轮轮廓曲面解析方程组 ,导出凸轮压力角解析表达式 。

The geometric relation of engage line seat between driven curved surface and cam one, which is a spatial geared cam mechanism with drum roller of follower (x Direction), has been analyzed by the method of rotary exchange tensor rule. The equations of cam curved surface of the mechanism and result in geometry formula of pressure angle are obtained,and the forming principle of spatial cam curved surface is stated.
