Abstract

The utility model discloses a bearing bush for a ship, relating to the technical field of bearing bushes. The bearing bush comprises two semi-cylindrical bush bodies (1), wherein a cylindrical bearing bush body (10) is formed by the two bush bodies (1); an annular oil groove (3) is formed in the inner sides of the bush bodies (1); an oil injection hole (4) is formed in the wall of the annular oil groove (3) of the corresponding bush bodies (1); a plurality of axial through holes (2) are molded in the bush bodies (1); the axial central lines of all the through holes (2) are parallel to the axial central line of the cylindrical bearing bush body (10). The bearing bush for a ship disclosed by the utility model has a higher heat dissipation property and thus the service life of the bearing bush is prolonged.

Description

A kind of bearing shell peculiar to vessel

Technical field:

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

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 there is impurity or viscosity is abnormal etc. that factor causes tile kilning due to excessive, the excess Temperature of load, lubricant oil, after tile kilning, sliding bearing has just damaged, it is by bush seat, being provided with space for existing bearing shell peculiar to vessel, bearing shell is arranged in bush seat, thereby reduce the operating temperature of bearing shell, its DeGrain, poor radiation, the working life of having reduced bearing shell.

The model utility content:

The purpose of this utility model is exactly the deficiency for prior art, and a kind of bearing shell peculiar to vessel 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 bearing shell peculiar to vessel, 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, in described watt of body, form many axial holes, the longitudinal center line of all through holes parallels with the longitudinal center line of bearing shell body.

Described all through holes cross section is the circle that size is identical, and all through holes are evenly distributed in watt body.

On described watt of body, two ends form respectively along the radially extended gulde edge of watt body.

The beneficial effects of the utility model are:

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

The accompanying drawing explanation:

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.

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

Embodiment:

The following stated is only 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 bearing shell peculiar to vessel, 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 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 holes 2 cross sections are the circle that size is identical, and all through holes 2 are evenly distributed in watt body 1.

On described watt of body 1, two ends form respectively along the radially extended gulde edge 11 of watt body 1.

Working principle: when bearing shell moved, its heat, from the axial hole 2 watt body 1, coming out, was taken away heat from mobile through hole 2 temperature of fast reducing bearing shell, thereby the working life of improving bearing shell by air.
