Abstract

The utility model relates to a bearing bush in a novel assembling mode. The bearing bush comprises a bearing bush body (2), a cylindrical pin (4) and a through hole (5), wherein the bottom of a pump body (1) is provided with a variable disc (3); the center of the variable disc (3) is provided with a cylindrical surface; the bearing bush body (2) is arranged below the cylindrical surface and has a C-shaped section; and the through hole (5) is formed in the center of the bottom of the bearing bush body (2). By the bearing bush in the novel assembling mode, the connecting stability between the bearing bush body and the variable disc can be improved.

Description

A kind of bearing shell of new fit

Technical field

The utility model belongs to the hydraulics field, particularly relates to a kind of bearing shell of new fit.

Background technique

In A10VSO series axial piston pump structure; Secondary cu bearing liner is generally arranged, between the variable dish and the pump housing when variable dish variable, owing to have frictional force between the variable dish and the pump housing; Make bearing shell have the trend of motion; So the shape that the two ends of bearing shell are designed to give prominence to also is stuck on the pump housing, is broken sometimes in the outstanding part in process intermediate bushing two ends of debugging, and breaks the normal use that the part of getting off can have a strong impact on pump.

The model utility content

The utility model technical problem to be solved provides a kind of bearing shell of new fit, can improve connection stability.

The utility model solves the technological scheme that its technical problem adopted: a kind of bearing shell of new fit is provided, comprises the pump housing, bearing shell; The variable dish, straight pin and through hole, described pump housing bottom is equipped with a variable dish; Variable disk center position is a cylndrical surface; Under the cylndrical surface bearing shell is installed, the bearing shell cross section is the C type, and there is a through hole center, bearing shell bottom.

Described bearing shell is installed on the pump housing through the cooperation of straight pin and through hole.

The upwardly extending height of both sides free end of described bearing shell surpasses the height of variable dish horizontal plane.

Beneficial effect

The utility model is a half-circle-arc shape, and bore a diameter in bearing shell bottom be 2.5 through hole, simultaneously also on the pump housing drill diameter be 2.5 blind hole, be connected through straight pin between bearing shell and the pump housing, can improve bearing shell and variable dish connection stability.
