Dynamic Analysis of Spiral Bevel Gear Pair under Time-Varying Backlash

Article Preview

Abstract:

Neglecting the influence of static transmission error, a non-linear dynamic model of spiral bevel gear pair with time-varying backlash was presented. Through the simplification of above model, the dimensionless form of gear system was obtained. Then, the dynamic characteristics of gear system were acquired by using Runge-Kutta method under the influence of time-varying backlash and torque. The results showed primary harmonic amplitude of gear backlash and torque had a significant effect on the non-linear and vibration characteristics of gear system. With the change of that, bifurcation phenomenon, quasi periodic motion and chaotic motion were detected. In addition, the variation and fluctuation of amplitude, containing displacement amplitude and velocity amplitude, were analyzed detailedly.
