This paper proposes a nonlinear time-varying transverse-torsional coupled model for a compound planetary gear sets based on the theory of the concentrated parameter. The influence of the position errors and the phase angle on the load sharing characteristics is analyzed by considering the bearing stiffness, time-varying meshing stiffness and gear backlashes of the gears. The analysis results show that the position errors of central member will make equal periodic changes for the system, while the position errors of the planetary gears will make sustained partial load. Meanwhile, it has no influence on the load sharing characteristics of the system when the phase angle of the position errors exists on the central members. However, it has some influences when the phase angle of the position errors exists on the planetary gears, and the load sharing coefficient is the largest when the phase angle is 90 degrees.
