| 摘 要： | 采用解析法推导了存在双偏心误差的渐开线齿轮副的传动误差计算公式，建立了其传动误差解析计算模型，同时分析了齿轮副的瞬时节点、传动比误差以及传动误差之间的等价关系；应用RecurDyn软件验证了传动误差计算模型；在啮合频率变负载的动态传动误差仿真的基础上，建立了与理论计算的传动误差及其侧隙值间的关系；在此基础上，针对已有偏心误差情况下，提出齿轮偏心误差初始相位的优化配置方法，得到最小传动误差，为精密传动设备的装配调整提供理论指导。

| Abstract: | A transmission error analytical mothed of dual-eccentric gears is proposed. The relation among instantaneous node, transmission ratio error, and transmission error is deduced. In order to demonstrate the validity of the analytical method, the solid model is constructed in the dynamics simulation software RecurDyn and the simulation transmission error is obtained. By comparison, the simulation transmission error curve agrees well with the analytical one. On this basis, dynamic transmission error under meshing frequency varying load is explored and the relation between dynamic transmission error, the theoretical transmission error and backlash is studied simultaneously. Finally, the optimum initial phase has been given to decrease the transmission error under the circumstance of fixed eccentricity |
