According to the traditional gear power split systems with parallel axes, star gear trains and planetary gear trains, we put forward a new power split system of spiral bevel gears and established its mechanical model. The moment equilibrium and deformation compatibility conditions of the system were proposed and the stiffness curves of gear pair were fitted. Then the power split situation of the system was calculated by an optimization method. The power split situations of the system with or without installation errors were obtained respectively, in an example of an aviation power split system of spiral bevel gears. The results show that the installation errors of shaft angle of the input gear and in axial direction of its adjacent output gear are beneficial to load sharing of the system, increase the load capacity of the main load-bearing gear and improve the vibration and noise of the system.
