Abstract

The utility model discloses a bearing bush with high heat dissipation, and relates to the technical field of bearing bushes. The bearing bush comprises semi-cylindrical bush bodies (1), and two bush bodies (1) form a cylindrical bearing bush body (10); an annular oil tank (3) is formed in the inner side of the bush body (1), and an oil injection hole (4) is formed on the wall of the bush body (1) corresponding to the annular oil tank (3); a plurality of axial through holes (2) are formed in the bush body (1); and the axial central lines of all through holes (2) are parallel to those of the bearing bodies (10). The bearing bush is high in heat dissipation, so that the service life of the bearing bush can be prolonged.

Description

A kind of high heat radiation bearing shell

(1) technical field

The utility model relates to the bearing shell technical field, and what be specifically related to is a kind of high heat radiation bearing shell.

(2) background technique

Bearing shell is the sliding bearing important component part, when axle turns round in the bearing shell high speed, it can produce a large amount of heats, the high temperature that direct friction produces burns out bearing shell, also may be because excessive, the excess Temperature of load, lubricant oil exist the factors such as impurity or viscosity be unusual to cause tile kilning, sliding bearing has just damaged behind the tile kilning, it is by being provided with the space in bush seat for existing bearing shell, bearing shell is installed in the bush seat, thereby reduce the operating temperature of bearing shell, its DeGrain, poor radiation, the working life of having reduced bearing shell.

(3) model utility content

The purpose of this utility model is exactly the deficiency for prior art, and a kind of high heat radiation bearing shell is provided, and it has higher thermal diffusivity, improves the working life of bearing shell.

Technology solution of the present utility model is as follows:

A kind of high heat radiation bearing shell, comprise half-terete watt of body, two watts of bodies form a columned bearing shell body, there is annular oil groove the inboard of watt body, watt body wall that annular oil groove is corresponding is provided with oil hole, form many axial holes in the described watt of body, the longitudinal center line of all through holes parallels with the longitudinal center line of bearing shell body.

Described all through hole cross sections are the identical circle of size, and all through holes are evenly distributed in watt body.

Two ends form respectively along the radially extended gulde edge of watt body on the described watt of body.

The beneficial effects of the utility model are:

It is by a plurality of axial holes of moulding in watt body, and is in service at bearing shell, when air flows from axial hole, will take away the heat in the bearing shell, simultaneously, the heat in the bearing shell also axial hole from watt body comes out, thereby the heat in the fast reducing bearing shell improves bearing shell working life.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1.

Among the figure: 1, watt body; 11, gulde edge; 2, through hole; 3, annular oil groove; 4, oil hole; 10, bearing shell body.

(5) embodiment

The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.

Embodiment: see shown in Fig. 1 to 2, a kind of high heat radiation bearing shell, comprise half-terete watt of body 1, two watts of bodies 1 form a columned bearing shell body 10, there is annular oil groove 3 inboard of watt body 1, watt body 1 wall of annular oil groove 3 correspondences is provided with oil hole 4, forms many axial holes 2 in the described watt of body 1, and the longitudinal center line of all through holes 2 parallels with the longitudinal center line of bearing shell body 10.

Described all through hole 2 cross sections are the identical circle of size, and all through holes 2 are evenly distributed in watt body 1.

Two ends form respectively along the radially extended gulde edge 11 of watt body 1 on the described watt of body 1.

Working principle: when bearing shell moves, come out in the axial hole 2 of its heat from watt body 1, flow from through hole 2 by air heat is taken away, the temperature of fast reducing bearing shell, thereby the working life of improving bearing shell.
