Plane oil distribution hydraulic motor limiting structure

Abstract

The utility model discloses a plane oil distribution hydraulic motor limiting structure which comprises a rear cover installed below a plane oil distribution hydraulic motor, a linkage shaft is arranged in the plane oil distribution hydraulic motor, a round installation cavity is formed in the top of the rear cover, a limiting column body is installed in an inner cavity of the round installation cavity, and a limiting rod is installed in the limiting column body. The bottom end of the linkage shaft extends to an inner cavity of the limiting column body, and a mounting assembly is arranged between the limiting column body and the inner wall of the circular mounting cavity. According to the utility model, the circular mounting cavity is processed on the rear cover, and then the limiting column body is mounted in the inner cavity of the circular mounting cavity through the mounting assembly, so that the end part of the universal driving shaft can move under the limitation of the limiting column body in the rotating process of the universal driving shaft, and the movement of the limiting column is limited; therefore, the purposes that a limiting column mounting hole is machined in the rear cover of the motor, and the limiting column is mounted in the hole during assembly, so that the moving space of the limiting column is limited, and the noise in the motor is reduced are achieved.
