Abstract:Based on the theory of lumped parameters, a translation-torsion coupling nonlinear dynamic model of herringbone planetary gear train was presented. The model considers multiple meshing phase relationship of the herringbone planetary gear transmission system, time varying meshing stiffness is derived. The support stiffness and error excitation of each member are considered synthetically. The effects of meshing phase on load sharing of the herringbone planetary gear is studied, the results show that:in the condition of ideal mesh, when meshing phase coefficient of the uniform type herringbone gear planetary gear system is 0, the system load sharing coefficient is 1, and the system translational vibration was inhibited; When meshing phase coefficient of the non uniform type herringbone gear planetary gear system is 0, the system load sharing coefficient is 1, and the system translational vibration was partly inhibited. The load sharing coefficient of herringbone planetary gear system with 0 meshing phase is smaller than that with different meshing phase. Geometry phase adjustments don't change the transmission ratio and size of the herringbone planetary train. Adjustments of the relations of planetary gear tooth number, although the transmission ratio and the size of the system will change slightly, but the load sharing coefficients are more smaller, and the system translational vibration was inhibited. The load sharing experimental study of planetary gear system with different meshing phase is conducted on single stage test herringbone planetary gear bench, which verifies the theoretical analysis. © 2018 Journal of Mechanical Engineering.
