Gear vibration and noise are important parameters that affect the transmission performance.The vibration and noise control of the gear transmission system has become a very important field.Presently, the main methods of vibration dorisvale station for sale control of the gear transmission system are increasing coincidence, shape modification, displacement, damping, etc.In this study, a novel method of staggered tooth phase of gears is proposed, the meshing principle of staggered phase tuning gears is studied, the calculation formula of time-varying meshing stiffness of staggered phase tuning gears is derived, and the mapping relationship between staggered phase and vibration response is studied.The experimental scheme of the parallel shaft spur gear pair with different staggering phases is designed, the experimental study of vibration reduction effect of gear pair with different staggering phases is carried out, and the experimental results are compared and analyzed with click here the simulation results.
