【Abstract】 In this paper, dynamic load, together with impact load, of the cage in the main roller bearing of an engine is considered. Based on dynamic characteristics and colliding mechanism, colliding vibration model is established. Then colliding vibration problem is solved to show the interaction between the cage and the other parts of the bearing.更多还原
