Effect of Machined Tooth Surface Mixed Lubrication Sliding Wear on Gear Dynamic Characteristics

Tooth surface wear causes variation in meshing stiffness and transmission error of the gear system further fluctuation dynamic characteristics. In this study, a behavior prediction model was established, which considered machined tooth based on mixed lubrication sliding tribology-dynamic model. The pair characteristics along line were analyzed through simulations, impacts conditions, operating torque, speed with discussed. results demonstrated that vibration displacement amplitude had increased gradually increase degree intensified. initially increases then decreases rotating speed.
