Abstract： In order to obtain the overturning stifness and fatigue performance of RV reducer main bearing，a main bearing test bench was developed，which might accurately measure the overturning stifness and fatigue life of RV reducer main bearings. The working principle and detailed structure of the test bench were emphatically introduced. The main bearing test bench consisted of mechanical systems，electric control systems and measurement software. The overturning stiffness of RV-125N reducer with different main bearing preloads was tested，and the fatigue test of RV-125N reducer with main bearing preload of （2号 0.06mm was carried out，and the failure mode and principle of the main bearing after the fatigue test were discussed.A three-dimensional analytical model of the RV-125N reducer was developed based on the experimental conditions in Masta software，and the life of the main bearing of RV-125N reducer was simulated and analyzed，and the simulation results show that the theoretical lifetime is 89% of the actual lifetime. The development of the test bench solves the problems of inaccurate overturning stiffness tests of the main bearings and the dificulty of fatigue life verification，and provides theoretical value and practical appli cation value for the design and manufacture of RV reducers.
