摘　　要：通过对行星分度凸轮机构凸轮理论廓线的连续性、正则性和自交现象等几何性质的分析 ,确定了从动件运动规律、变位系数和分度数对凸轮廓线设计的影响 ,建立了机构参数选取的几何约束条件。Through the analysis on geometrical properties of continuity, regularity and self-intersecting phenomena of theoretical cam contour in planetary indexing cam mechanism, this paper determined the influence on cam contour design affected by motion law of follower, coefficient of displacement and indexing number, and established conditions of geometrical restraint for parameter selection of mechanism.
