摘　　要：运用回转张量法和空间啮合原理,推导出一种新型的以钢球作为滚子的弧面凸轮分度机构的凸轮廓面方程和啮合方程,对分度机构接触点的受力情况进行了静力分析,推导出输入扭矩和输出扭矩的关系式。The cam profile surface equation and its engagement equation of a new type of steel ball indexing mechanism with arc surface cam are deduced by rotating matrix operators and the spacial joggle theory. The contiguity spot's power of the mechanism is analysed. And the connection expression of inputing torque and output torque is deduced.
