摘　　要：传动误差作为行星齿轮传动重要的性能参数之一,反映了工作时的精度问题,而长时间工作造成的齿面磨损会影响传动精度。针对该问题,以3z⁃Ⅱ型行星传动为研究对象,考虑齿轮固有误差以及各零件的安装误差建立整个传动系统的传动误差模型,并利用概率分析及蒙特卡罗方法进行模拟计算,得到接近实际的理论传动误差模型。基于Archard磨损模型,结合赫兹接触模型,建立齿轮的磨损模型。得到各个齿轮的齿面磨损深度,将各个齿轮的磨损深度等效为齿廓误差,建立基于齿面磨损的传动误差模型。对两个模型的仿真结果对比分析,考虑磨损时,整个传动系统的传动误差有所增加,传动误差集中在-0.42′~3.75′,平均值为1.71′;相比无磨损时,正向传动误差增大,负值降低。As one of the important performance parameters of planetary gear transmission,transmission error reflects the preci⁃sion problem at work,while the tooth surface wear caused by long-time work will affect the transmission precision.In view of this problem,taking 3z⁃Ⅱtype planetary gear as the research object,considering the inherent error of gear and installation error of each part,the whole transmission system transmission error model was established.By using probability analysis and Monte Carlo method for simulation calculation,theory transmission error model closed to the actual was obtained.Then,based on Archard wear model and Hertz contact model,the gear wear model was established.The wear depth of each gear was obtained,and the wear depth of each gear was equivalent to the tooth profile error,and the transmission error model based on the tooth surface wear was established.By compa⁃ring and analyzing the simulation results of the two models,the transmission error of the whole transmission system increases when con⁃sidering wear,the transmission error is concentrated in-0.42′to 3.75′,the average value is 1.71′;compared with no wear,the positive transmission error increases and the negative value decreases.
