Problems solved by technology

[0003] Inclined-axis pumps or motors usually use the main shaft to connect the plunger to drive the cylinder to move. The torque of the plunger is very large. If the force points of several plungers are not uniform, the plunger is easy to twist and the hole in the cylinder will be damaged. Due to uneven force, there are phenomena such as strain or cylinder locking

Abstract

The invention relates to an oblique-axis conical tooth pump. The oblique-axis conical tooth pump comprises a rotor shell and a bearing shell, the rotor shell and the bearing shell are connected with each other, a sealing ring I is arranged at the joint between the rotor shell and the bearing shell, a plug I is arranged on the rotor shell, a plug II is arranged on the bearing shell, a conical toothcylinder body is arranged in the rotor shell, conical teeth are arranged at one end of the conical tooth cylinder body, the conical tooth cylinder body is connected with the rotor shell through a central pin, an oil distribution disc is arranged at the joint between the conical tooth cylinder body and the rotor shell, the oil distribution disc is connected with the rotor shell through a positioning pin I, the center pin is arranged in a central hole of the conical tooth cylinder body, and needle bearings are arranged in the central hole, and sleeve the central pin. The oblique-axis conical tooth pump has the advantages that the noise is small, the volume is small, the displacement is large, the weight is light, the efficiency is high, the torsion is small, the operation is light and quick, the service life of an accessory is long, and the energy consumption is low.

Description

technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to an inclined-axis bevel gear pump. Background technique [0002] Existing thru-shaft swash plate pumps or motors mostly use shaft splines to drive the cylinder body, and the cylinder body then drives the plunger to complete the work. In this way, the friction between the sliding shoe and the swash plate is relatively large, and the torque is also large when rotating, which is easy to generate heat. , accessories are easily damaged. At the same time, the angle of the swash plate should not be too large, generally no more than 25 degrees, and the displacement is small and heavy. [0003] Inclined-axis pumps or motors usually use the main shaft to connect the plunger to drive the cylinder to move. The torque of the plunger is very large. If the force points of several plungers are not uniform, the plunger is easy to twist and the hole in the cylinder will be damaged. ...
