Novel high-power-density bifurcated transmission system

The invention discloses a novel high-power-density bifurcated transmission system. The novel high-power-density bifurcated transmission system is characterized in that an input shaft is installed on a box body through an input lower bearing and an input upper bearing, gear teeth are arranged above the input shaft in a machined mode, and the gear teeth mesh with an end face gear and an output gear shaft simultaneously; the left end of the output gear shaft is supported on a box body cover through an output left bearing , the right end of the output gear shaft is supported on a box body through an output right bearing, and the end face gear and the output gear shaft mesh with a gear shaft simultaneously, wherein the gear shaft is located at the upper end of the box body; and the gear shaft is installed on the box body through a gear shaft lower bearing and a gear shaft upper bearing, the output gear shaft meshes with the input shaft and the gear shaft simultaneously, and the end face gear meshes with the input
