Nonlinear dynamics of non-orthogonal offset face gear-bearing transmission system

Abstract

A nonlinear dynamic model of a non-orthogonal offset face gear-bearing transmission system is established, in which nonlinear factors such as input load fluctuation, gear clearance, bearing clearance, and transmission error are considered. The dynamic response of the system is analyzed by solving the differential equation with the numerical method. The subharmonic resonance and primary resonance characteristics of the torsional vibration displacement are analyzed by the multi-scale method. The results show that the change of meshing damping will make the system present rich nonlinear characteristics, and the equivalent static load and meshing damping ratio will affect the resonance characteristics of the system. Choosing the appropriate system parameters can make the system in a stable state and suppress the amplitude of primary resonance and subharmonic resonance.
