摘　　要：建立了行星齿轮机构拓扑图模型,通过行星齿轮机构类型综合,获得部分2自由度、3自由度行星变速机构拓扑图图谱。重点介绍了在行星齿轮机构综合过程中,拓扑图同构判别和刚性子链判别方法。按照一定的转换规则,将行星齿轮机构拓扑图转化为标准拓扑图形式,再将标准拓扑图转换成运动简图,得到部分双行星排、三行星排齿轮传动方案。The topological graph of planetary gear mechanism is established.Some topological graphs of two and three DOF planetary gear mechanism are synthesized.The procedures of isomorphism identification and rigid subchain detection are particularly presented.According to the transformation rules,topological graphs of planetary gear mechanism are converted into standard topological graphs and kinematic diagrams.Some trans⁃mission schemes of two planetary rows and three planetary rows are obtained.
