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