Study on dynamic characteristics of start and stop of RV reducer main bearing under eccentric load
In order to obtain the dynamic response characteristics of the main bearing under the starting and stopping conditions of the RV Reducer, taking the main bearing of a certain RV Reducer as the research object, the radial and axial eccentric loads of the bearing were analyzed. On this basis, the mult...

| description | In order to obtain the dynamic response characteristics of the main bearing under the starting and stopping conditions of the RV Reducer, taking the main bearing of a certain RV Reducer as the research object, the radial and axial eccentric loads of the bearing were analyzed. On this basis, the multi rigid body dynamics simulation model of bearings was established, and the load, speed and contact parameters were set according to the working conditions, and the effectiveness of the model was verified. The influence law of the starting and deceleration stop working conditions of the main bearing of RV Reducer on the contact force between the bearing roller and the cage and the inner and outer rings was simulated and analyzed. The results show that the contact force between the main bearing roller and the cage of RV Reducer is affected by the starting and stopping working conditions, and the collision is the most intense in the starting and accelerating stage, followed by the stable stage, and the minimum in the deceleration stage. The fluctuation range of the contact force between the roller and the inner ring during the starting acceleration and deceleration stop stages is 1. 5 times that of the smooth operation, which provides a theoretical basis for the study of dynamic characteristics and the life test of the main bearing of RV Reducer. |
