Abstract：A dynamics model of power split gear transmission system with four branches and 32-degree-of-freedom vibration equation are established. A gear meshing stiffness calculation method based on time-varying contact line equation is put orward. The law of each gear pair's dynamic load coefficient and load sharing coefficient under the time-varying mesh stiffness excitation with different installation angles of the system are studied. The results show load sharing coefficients of gear pairs in the second and third stage of the system rise with increase of the installation angle. When the installation angle reaches 120 degree, the maximum load sharing coefficient values are 1.288 and 1.291 respectively. These values experience no longer significant change while increasing the installation angle.
