） 摘要： 为准确获得内平动分度凸轮机构的受力状态

the intervals of each forced pin at the indexing period was given

It is concluded that number of meshing pins is more than half of total pins during most of the indexing period

Variation of the meshing number might have impact on the dynamic performance of the mechanism

The minimum meshing number can be decided by the tooth-tip to some extend

Keywords： mechanical design; force condition; multi-tooth meshing; indexing cam 下载PDF阅读器 PDF全文下载： 修改稿 1（ 69 ） 初稿 （ 158 ） 作者简介： 刘明涛
