Abstract: 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.
