Abstract

The invention belongs to the technical field of hydraulic pumps, and particularly relates to an inclined shaft plunger type hydraulic motor pump which comprises an inclined shaft pump assembly, the inclined shaft pump assembly comprises an inclined shell and a straight shell which are connected, a cylinder body is rotationally assembled in the inclined shell, a driven bevel gear is arranged on the cylinder body, a plunger is assembled in the cylinder body in a sliding mode, and the plunger is connected with a plunger connecting rod; and the inclined shaft plunger type hydraulic motor pump further comprises a motor, the motor comprises a motor shaft and motor end covers located outside the two ends of the motor shaft, and the straight shell is connected with one motor end cover. The inclined shaft pump assembly further comprises a transmission shaft, one end of the transmission shaft is inserted and fixed from the end face of one end of the motor shaft, the other end of the transmission shaft is provided with spherical hinge seats corresponding to the plunger connecting rods, the corresponding ends of the plunger connecting rods are assembled in the corresponding spherical hinge seats, and the transmission shaft is further provided with a driving bevel gear meshed with the driven bevel gear. And a sealing structure is arranged between the transmission shaft and the straight shell and / or the motor end cover to prevent liquid from entering the motor.

Description

Technical field [0001] The present invention belongs to the technical field of hydraulic pumps, and more particularly to a slanted axial hydraulic motor pump. Background technique [0002] The motor drive hydraulic pump provides high-end mobile equipment to provide hydraulic energy, low noise, weight and maintenance. Conventional screw-shaped plunge hydraulic motor pumps are three-stage structures, typically including a bevel shaft pump assembly and a motor, and the shaft pump assembly includes an oblique housing, a straight housing, a housing mounting a cylinder, a straight shell The bearing is rotationally assembled with a spindle. It is provided with an active tapered teeth on the spindle. The cylinder is provided with a movable tapent tooth, and the motor is connected to the main shaft through the coupling, and rotates by the spindle. As the mandate bulletin is the scallet pump in the Chinese practical novelty of CN207470369U, this structure, the spindle (i.e., the spindle di...
