description To explore the coupling effect of gear dynamics characteristics and elastohydrodynamic lubrication, considering the influence of surface roughness and the time-varying meshing stiffness on gear dynamics behavior, the six-degree-freedom friction dynamics model is established based on the dynamics theory. The decoupling method is adopted to solve the model to get the dynamic meshing force and the gear teeth surface wave velocity which are used for elastohydrodynamic lubrication analysis. And the elastohydrodynamic lubrication characteristics of gears under dynamic and static load models are studied by an example. The results show that, compared with the stationary load, the elastohydrodynamic lubrication research based on dynamic load model can more accurately reflect the transient lubrication characteristics of gear. Under the incentive of time-varying stiffness, the oil film pressure and oil film thickness during lubrication show certain oscillation effect. There is greater impact on the entry point, single-tooth entry point and single-tooth exit point which are the dangerous points of elastohydrodynamic lubrication.
