Dynamics Characteristics and Experiment Research on Planetary Gear System
摘要
Abstract
Using lumped mass model, the nonlinear dynamic model of one planetary gear transmission system is established, considering time varying stiffness, backlash, lateral and vertical displacement of the sun gear, eccentricity error excitation of the sun gear and planetary gear. The response, phase diagram, frequency spectrogram and dynamic load sharing coefficients of the system are solved by Runge-Kutta method. And the phase diagram, frequency spectrogram and dynamic load sharing coefficients of the strain-deformation of gear tooth root are obtained by means of measuring the stress and the strain of ring gear tooth root. The results show that the theoretical analysis results agree well with the experimental results, so the dynamics model is reasonable, and the test plan is feasible.关键词
