Bearing-free cycloid hydraulic motor structure

The utility model provides a bearing-free cycloid hydraulic motor structure. The bearing-free cycloid hydraulic motor structure comprises a rear shell, a valve plate, a stator and rotor assembly and a linkage shaft, wherein a connection flange is fixedly mounted at one end of the rear shell, which is close to the linkage shaft; the end face of the connection flange, which is close to one side of the linkage shaft, is a sealing face; and a connection hole is formed in the connection flange. The technical scheme has the advantages that a power output part is directly changed, so that parts including an output shaft, a bearing shell, a bearing, a partition board, a framework oil seal and the like do not need to be machined; and on the premise of ensuring geometric accuracy, the limitation on equipment in a machining process can be reduced, the machining difficulty and the machining cost are reduced, a user can conveniently use and mount, the maintenance time and the cost can be reduced, the loss brought by maint
