Abstract

Impedance models of gear, shaft, bearing and housing are built respectively, and impedance synthesis approach is adopt to establish gear-shaft-bearing-housing coupled dynamic model, which accomplished the couple between gear transmission system with housing. Taking a single-stage helical gear pair gearbox as an example, natural frequency of “gear-shaft-bearing-housing” system is computed, and gear dynamic mesh force and bearing dynamic reaction force under time-varying mesh stiffness excitation are obtained. A comparison between the coupled configuration and the uncoupled case shows that: the coupling of housing reduces system natural frequencies; influence of housing compliance on bearing reaction force is more prominent than influence on gear mesh force; whether gearbox housing will decrease or increase system vibration depends on operation speed.
