摘要:
Meshing parameters including stiffness and damping are key factors of nonlinear vibration of spiral bevel gears. Considering the time-varying characteristics of meshing stiffness and meshing damping, adopting a second-order Fourier series, vibration equation of a pair of spiral bevel gears was established. Based on the variation of clearance function under different meshing states, the effects of meshing stiffness and meshing damping on meshing features of a pair of spiral bevel gears under three meshing states were studied. Using Matlab, the vibration displacement curves of the meshing point were given when mean meshing damping, harmonic meshing damping, major harmonic meshing stiffness and sub-harmonic meshing stiffness were considered. The results showed that increasing mean meshing damping and decreasing major harmonic meshing stiffness can drop vibration displacement peaks and improve transmission stability.
