Novel wind power gear box

A novel wind power gear box belongs to the technical field of mechanical gear boxes and comprises a box body for supporting, and an input end, an intermediate stage and an output end are mounted in the box body and sequentially connected. Therefore, the structure can effectively reduce the return difference problem of the planetary gear train caused by manufacturing and mounting errors, so that the processing and mounting requirements on high-speed components can be properly reduced by utilizing the structure; the reliability of a design object is improved, so that the design object can be suitable for a power generation occasion with MW-level power; by means of the structure, axial force can be counteracted, the axial force on the shaft is reduced, the joint of the shaft can be fixed through the elastic check ring and connected with the gear coupling, meanwhile, the most beneficial floating uniform load mode is achieved, and the adverse effect of unbalance loading on reliability is reduced. 一种新型风电齿轮箱，属于机械齿轮箱
