Analysis of the Load Sharing of the Flexible Ring Gear Planetary Gear Train

Abstract

The lumped mass model-finite element hybrid model with flexible ring gear is proposed. The dynamic model of planetary transmission system with flexible ring gear structure is established. The calculation of internal meshing time variation between flexible ring gear and planetary gear is proposed. The method of meshing stiffness. According to Newton's second law, the planetary gear train dynamics load model considering time-varying meshing stiffness, damping, comprehensive meshing error and thin-walled sleeve inner ring gear is derived. The planetary gear train with flexible ring gear structure is established. The dynamic equations are solved by numerical methods. The dynamic load-carrying characteristics of the planetary gear trains with different inner sleeves and inner ring gears with different sleeve thicknesses are analyzed. The results show that the inner ring gear sleeve wall The thinner the thickness, the greater the flexibility of the inner ring gear, the smaller the meshing stiffness during internal meshing, the better the load sharing performance of the system, and the internal meshing load factor is more affected.
