Abstract

Based on the previous research on the dynamical model of gear mechanism with multiple clearances coupling, a dynamic experiment with multiple clearances coupling is proposed. Radial clearance and tooth backlash are considered in the experiment, and the valuses of radial clearance and tooth backlash are adjustable. With the measurement of vibration performance, the vibration frequency and amplitude of the different rotating speed and clearance are analyzed. The results prove that, compared with the traditional multiple clearances model, the dynamic model of multiple clearances coupling is more consistent with the experimental data in the calculation of the frequency and amplitude. And the new model can also reflect the coupling vibration phenomenon caused by multiple clearances collisions.
