摘　　要：采用渐开线齿轮替代RV传动中的摆线针齿,重新设计了一款渐开线2K-V型行星减速器,并建立了减速器的三维实体模型;运用ABAQUS有限元软件对减速器关键的第二级内啮合进行静力接触仿真分析,得到轮齿啮合齿对数和载荷分配情况,与理论计算结果进行了对比,并进一步比较了不同转矩作用下的接触载荷与多齿弹性啮合效应系数;最后,考虑了实际工况中齿轮接触摩擦生热的影响,进行了额定转矩下的力热耦合稳态接触仿真,得到各轮齿的温度场分布与齿轮副的热应力情况,验证了减速器的接触特性。By using the involute gears instead of the cycloid pin gears in the RV reducer,a 2K- V involute planetary gear reducer is redesigned,and a three dimensional model of the reducer is established. The static contact simulation of the internal meshing which is a key part of the reducer is proceeded by the finite element analysis software ABAQUS. Then,the meshing tooth pairs and the load distribution are obtained and compared with the results of theoretical calculation. A further comparing of contact load and the elastic meshing effect coefficient under different torque is conducted. Finally,considering the influence of gear frictional heat,a steady- state coupled contact simulation under rated torque is carried out,the temperature field distribution and the thermal stress distribution of the tooth are obtained,the reliability of the gear contact characteristic is proved.
