The application discloses a reducer with high-speed bearing non-forced lubrication structure and belongs to the technical field of reducers. The reducer solves the defects that the high-speed bearing in the electric drive bridge reducer is prone to insufficient lubrication and further causes dry grinding of the bearing under the condition that only splash lubrication is adopted and an auxiliary oil pump is not added. The reducer mainly comprises a main reducer shell and a three-shaft gear. An axle bearing mounting hole is arranged on the inner wall of the main reducer shell. The three-shaft gear is mounted in the main reducer shell. The axle bearing mounting hole is communicated with an axle bearing oil inlet hole. An oil receiving cover assembly is fixedly mounted on the inner wall of the main reducer shell. The oil receiving cover assembly is in a curved channel structure. The oil receiving cover assembly is provided with a large port and a small port. The large port is downwardly opened and is arranged along the tangential direction of the three-shaft gear. The small port is communicated with the axle bearing oil inlet hole.
