摘 要：
环式减速机在使用过程中常出现振动、噪声、发热等问题,因此设计了一种两级同轴环式减速机,对其结构特点及传动原理进行了分析,在综合考虑齿轮系统时变刚度、齿侧间隙和制造误差的基础上,建立了该减速机的齿轮转子支承全系统耦合非线性动力学模型,在考虑系统内部激励的情况下对该耦合系统动态特性进行了研究,验证了该结构的合理性。

摘 要：
Ring reducer was developed due to its remarkable features such as high transmission ratio, heavy load-capacity and compact structure and so on. However, the disadvantages of the ring reducer including vibration, noise, and overheating, are inevitable in the original structural design of the ring reducer during the operation process. To overcome these problems, a new two-stage coaxial ring-reducer is first proposed in the paper. Moreover, the whole system dynamic model is established through considering the non-linear coupling of gears, shafts and bearings. This dynamic model also takes into account the time-varying stiffness, running clearance and manufacturing errors. Finally, the principle and features of the new two-stage coaxial ring-reducer are analyzed. The new structural design is verified through simulation results.
