The influence of rotation speed on gear rattle under Overdrive

摘要

Overdrive transmission is easy to rattle. In gear system, rotation speed is one of the important parameters affecting gear rattle. A numerical method for gear rattle simulation at different rotation speed is proposed, which combines the model of gear rattle with the actual motion of gears. Aiming at the relative velocity, which is one of the most important parameters to evaluate the intensity of gear rattle, computational simulation and experimental verification is finished about the influence of different rotation speed on gear rattle with error excitation under overdrive. The experiment and simulation results show that with the rotation speed rising, the amplitude of relative velocity of gear rattle increases, which indicates severer gear rattle.
