Dynamic Characteristics Analysis of Gear-Bearing System Considering Dynamic Wear with Flash Temperature

The influence of the dynamic wear model considering the tooth contact flash temperature on the dynamic characteristics of a gear-bearing system is studied. Firstly, the meshing stiffness model, based on flash temperature theory, is established. Then, the changing of tooth surface temperature and mes...
