中文摘要：

在分析现有环式减速机传动原理及存在问题的基础上,首次提出一种由一级普通圆柱齿轮传动和一级双环减速传动构成的新型两级同轴环式减速机。对该减速机的结构特点、传动原理进行分析,利用接触有限元对该减速机内啮合齿轮副实际接触齿对数及轮齿强度进行计算。采用动态子结构法建立该减速机齿轮—转子—轴承—箱体系统耦合三维有限元动力学分析模型,在考虑轮齿时变刚度、齿侧间隙和制造误差等内部激励的情况下,对系统动态性能进行了仿真,在齿轮传动试验台上对该减速机动态性能进行试验研究,验证了理论分析结果的正确性。

英文摘要：

On the basis of the analysis of existing ring-reducer principle and its disadvantages, a new ring-reducer with small tooth number difference parallel movable axis, which consists of two stage transmissions-cylinder gear transmission and double-ring reducer transmission, is first proposed.The principles and features of the new two-stage coaxial ring-reducer are analyzed, and load-carrying capacity of the reducer is calculated. Moreover, the whole system dynamic behavior is simulated by considering the non-linear coupling characteristic, this dynamic model also takes into account the inner excitation. Finally, The physical prototype of the new structural is manufactured and tested to verify its rationality.
