Abstract

The invention provides a through-shaft axial swash plate plunger pump. The through-shaft axial swash plate plunger pump comprises a shell body, wherein an end cover is arranged at the left end of the shell body, a tail cover is arranged at the right end of the shell body, a cylinder body is arranged inside the shell body, and a rotating shaft is arranged on the left end surface of the cylinder body; a swash plate is arranged at the position, located on the left side of the cylinder body, of the shell body, and the swash plate is arranged on the rotating shaft in a sleeving mode; a supporting shaft is arranged on the right end surface of the cylinder body; a front bearing is arranged in the swash plate, and the front bearing is arranged on the rotating shaft in a sleeving mode; and a rear bearing is arranged in the tail cover, and the rear bearing is arranged on the supporting shaft in a sleeving mode. The structure of the plunger pump can improve the stress condition effectively, and the displacement of the cylinder body during rotation is small, so that the plunger pump has the advantages of being stable in operation, low in vibration, low in noise and long in service life.

Description

technical field [0001] The invention relates to the field of hydraulic pressure, in particular to a through-shaft axial swash plate plunger pump. Background technique [0002] The plunger pump is an important device of the hydraulic system. It mainly relies on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber to realize oil suction and oil pressure; the plunger pump in the prior art is generally in the cylinder. Bearing support is provided between the body and the housing. The plunger pump with such a structure has a large gap between the intermediate bearings, and the rotating body is easy to move when it is working, and the operation is not stable, resulting in greater vibration and noise. Contents of the invention [0003] The technical problem to be solved by the present invention is that the rotating body of the existing plunger pump is easy to move when it is working, and the operation is not stable, resultin...
