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

The influence of the dynamic wear model considering tooth contact flash temperature on characteristics a gear-bearing system is studied. Firstly, meshing stiffness model, based theory, established. Then, changing surface and in process gear analyzed. Next, initial calculated Archard Finally, effects wear, friction factors, damping ratio response are results show that with increase fractal dimension D, uncertainty fluctuation amplitude backlash decrease, force decreases. Therefore, reduced, stability improved; coefficient, rises, root mean square value vibration displacement amplifies, which indicates tends to be unstable; ratio, changes from unstable quasi-periodic chaotic motion stable periodic motion. accelerates energy loss makes prone stable.
