摘　　要：对弧面凸轮行星减速机构的内弧面凸轮和外弧面凸轮的包角进行了研究.在保证传动连续的条件下,推导了内、外弧面凸轮包角与行星轮个数和行星轮上滚动齿的个数等结构参数间的关系;在分析了内、外弧面凸轮的包角与啮合齿数的基础上,优化了内、外弧面凸轮包角的取值.通过案例分析,验证了模型的正确性,为后续该传动结构的设计和优化提供了理论依据.The inner and outer globoidal cams wrap angles of a globoidal cam planetary deceleration mechanism are explored.Under the condition of transmission continuity,the relationship between the inner and outer globoidal cam wrap angles and the structural parameters such as the number of planetary gears and the number of rolling elements on the planetary gear is deduced,and the relationship between the inner and outer globoidal cam wrap angles and the number of engaging points is analyzed,thereby optimizing the selection of values of the inner and outer globoidal cam wrap angles.Based on case analysis,the correctness of the model is verified,which provides a theoretical basis for the design and optimization of the transmission structure.
