含齿面磨损的多源激励下行星齿轮传动系统均载性能研究

In view of the problem that the load distribution of each component was uneven during the operation of the planetary transmission system, which affected the stability of the transmission system. A two-stage planetary transmission system was considered as the research object, and introduced the internal and external excitation such as relative floating between stages, gear backlash, comprehensive meshing error, time-varying meshing stiffness, and established a translation-torsion coupling nonlinear dynamic model of the transmission system considering the impact of tooth surface wear. The dynamic meshing force of the gear and the load sharing coefficient of the gear pair were obtained, and the influence of the number of tooth surface wear, the comprehensive meshing error with and without the relative floating clearance between stages, and the gear support stiffness on the load sharing performance were comprehensively analyzed, which laid a theoretical foundation for the in-depth study of the stability of the planetary gear system
