摘      要：Nonlinear dynamic analysis was performed on a planetary gear transmission system with meshing beyond the pitch *** parameters of the planetary gear system were optimized,and a two-dimensional nonlinear dynamic model was established using the lumped-mass ***-varying meshing stiffness was calculated by the energy *** model consumes the backlash,bearing clearance,time-varying meshing stiffness,time-varying bearing stiffness,and time-varying friction *** time-varying bearing stiffness was calculated according to the Hertz contact *** load distribution among the gears was computed,and the time-varying friction coefficient was calculated according to elastohydrodynamic lubrication(EHL)*** dynamical equations were solved via numerical *** global bifurcation characteristics caused by the input speed,backlash,bearing clearance,and damping were *** system was in a chaotic state at natural frequencies or frequency *** system transitioned from a single-period state to a chaotic state with the increase of the *** bearing clearance of the sun gear had little influence on the bifurcation *** amplitude was restrained in the chaotic state as the damping ratio increased.

主 题 词：meshing beyond pitch point planetary gear system nonlinear time-varying bearing stiffness timevarying meshing stiffness multiple clearances bifurcation time-varying friction coefficient
