为了提高RV(Rotate Vector)减速器的传动能力及传动精度,本文分析了RV减速器中摆线针轮传动部分的传动原理和齿廓形成,计算了摆线轮接触齿面摩擦热流量所需的各种参数,得出啮合接触区域的摩擦热流量及对流边界条件.通过三维建模,并运用有限元软件Ansys Workbench进行分析,得出了摆线轮齿在实际传动过程中的稳态温度场分布,考虑了不同输入功率和接触区条形区域划分数量对实际结果精度产生的影响,得出了最佳的条形区域划分数量为32.为提高机构整体传动精度、避免轮齿胶合、指导轮齿修形等更深入的研究奠定了基础.%To improve the transmission capability and precision of the RV reducer , this paper analyzed the transmis-sion principle and the tooth profile formation of pin-cycloid planetary gearing part for the RV reducer , calculated vari-ous parameters needed for the friction heat flux of the contact tooth surfaces of the cycloidal gear tooth , and obtained the friction heat flux and the convective boundary condition of the contact tooth surface .Through three-dimensional modeling and with the use of finite element analysis software ANSYS Workbench , this paper obtained the steady-state temperature field of the cycloidal gear tooth in the actual transmission process .Taking into account the effect of dif-ferent input power and the number of bar area division in the contact tooth surface , this paper derived that the optimal number of bar area division is 32.This paper establishes the foundation for further research to improve the overall transmission accuracy of the mechanism , avoid tooth scuffing , and guide the tooth profile modification .
