Prediction on the Wear Life of Bearings for Planetary Gears

Abstract:

In this paper, firstly, a dynamic model of planetary gears involving the bearing wear and a model to calculation of the bearing wear capacity will be established. And then the basic flow for prediction on the wear life of bearings for planetary gears will be given by the proposed two models. Finally, the influences of the bearing wear on the bearing wear life will be studied and the methods to improve the bearing wear life will also be discussed. The simulation and analysis results show that with the increase of the limit wear capacity, the bearing wear will experience three periods, such as rapid increasing, steady increasing and constant, and there are also a significant impact of the bearing clearance and stiffness on the bearing wear life.
