摘　　要：设计了一种一对多的间歇传动机构,并基于凸轮传动原理,运用无因次法,将传动槽设计为曲线槽。结合Matlab分析和ADAMS仿真,验证了槽销传动在拨销的速度方向与受力方向始终相反时,曲线槽可有效消除柔性冲击。运用SolidWorks对关键零部件进行拓扑优化,实现轻量化设计。结果表明:所提出的曲线槽间歇传动机构具有传动平稳、无柔性冲击等特点,轻量化设计后力学性能良好,可应用于工程实际中。A one-to-many intermittent transmission mechanism is designed.Based on the principle of cam transmission,the transmission groove is designed as a curved groove by using the dimensionless method.Combined with Matlab analysis and ADAMS simulation,it is verified that the curved groove can effectively eliminate the flexible impact when the speed direction of the pin is always opposite to the direction of the force.SolidWorks is used to optimize the topology of key components to achieve lightweight design.The results show that the proposed curve groove intermittent transmission mechanism has characteristics of smooth transmission,and non-flexible impact.It has good mechanical properties after lightweight design,and can be used in engineering practice.
