Abstract

The utility model discloses a high-heat-radiation bearing bush for a ship, relating to the technical field of bearing bushes. The high-heat-radiation bearing bush comprises semi-cylindrical bearing bush bodies (1), wherein an oil injection hole (11) is formed in the side wall of one bearing bush body (1); an annular oil groove (12) is formed in the inner walls of the bearing bush bodies (1); one end of the oil injection hole (11) is communicated with the annular oil groove (12); a plurality of convex semi-annular blocks (2) are molded on the outer walls of the bearing bush bodies (1); the circle centers of the plurality of convex semi-annular blocks (2) are on the central axes of the bearing bush bodies (1); a flow groove (3) is formed between each two semi-annular blocks (2); a plurality of axial through holes (21) are molded in the semi-annular blocks (2) and are communicated with the flow grooves (3) in the two sides of the semi-annular blocks (2). According to the high-heat-radiation bearing bush for a ship disclosed by the utility model, heat radiation can be rapidly performed in an operation process of the bearing bush and thus the service life of the bearing bush is prolonged.

Description

A kind of high heat radiation 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 high heat radiation bearing shell peculiar to vessel.

Background technique:

Bearing shell is the sliding bearing important component part, on its wall, oil hole is arranged, there is annular oil groove inboard, the annular oil groove lubricate, 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 load is excessive, excess Temperature, lubricant oil has impurity or viscosity is abnormal etc. that factor causes tile kilning, after tile kilning, sliding bearing has just damaged, it is by bush seat, being provided with space for existing general 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 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 peculiar to vessel is provided, and it can make the bearing shell quick heat radiating that carries out in service, 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 peculiar to vessel, comprise two half-terete bearing shell bodies, the sidewall of bearing shell body is provided with oil hole, bearing shell body inwall is provided with annular oil groove, oil hole one end communicates with annular oil groove, on the outer wall of described bearing shell body, form the semicircular ring piece of a plurality of projections, the center of circle of a plurality of semicircular ring pieces is on the central axis of bearing shell body; Between every two semicircular ring pieces, it is circulation groove; On the semicircular ring piece, be formed with a plurality of axial holes, through hole communicates with the circulation groove of the both sides of semicircular ring piece.

On described each semicircular ring piece, be formed with eight axial holes, the circulation groove axial length between every two semicircular ring pieces is identical.

On the outer wall of described bearing shell body, form the semicircular ring piece of three projections, the two ends of bearing shell body form respectively along the radially extended gulde edge of bearing shell body.

The beneficial effects of the utility model are:

It is by forming the semicircular ring piece of a plurality of projections on the outer wall at the bearing shell body, between every two semicircular ring pieces, it is circulation groove, on the semicircular ring piece, be formed with a plurality of axial holes, through hole communicates with the circulation groove of the both sides of semicircular ring piece, when flowing, circulation groove and axial hole will take away a large amount of heats when air like this, reduce the temperature of bearing shell body, improve the working life of bearing shell.

The accompanying drawing explanation:

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

Fig. 1 is perspective view of the present utility model;

Fig. 2 is side view of the present utility model;

Fig. 3 is structural representation of the present utility model.

In figure: 1, bearing shell body; 11, oil hole; 12, annular oil groove; 13, gulde edge; 2, semicircular ring piece; 21, through hole; 3, circulation groove;

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 that Fig. 1 is to shown in Figure 3, a kind of high heat radiation bearing shell peculiar to vessel, comprise two half-terete bearing shell bodies 1, the sidewall of bearing shell body 1 is provided with oil hole 11, bearing shell body 1 inwall is provided with annular oil groove 12, oil hole 11 1 ends communicate with annular oil groove 12, on the outer wall of described bearing shell body 1, form the semicircular ring piece 2 of a plurality of projections, and the center of circle of a plurality of semicircular ring pieces 2 is on the central axis of bearing shell body 1; Between every two semicircular ring pieces 2, it is circulation groove 3; On semicircular ring piece 2, be formed with a plurality of axial holes 21, through hole 21 communicates with the circulation groove 3 of the both sides of semicircular ring piece 2.

On described each semicircular ring piece 2, be formed with eight axial holes 21, circulation groove 3 axial lengths between every two semicircular ring pieces 2 are identical.

On the outer wall of described bearing shell body 1, form the semicircular ring piece 2 of three projections, the two ends of bearing shell body 1 form respectively along the radially extended gulde edge 13 of bearing shell body 1.

Working principle: bearing shell body 1 is arranged in bearing support and bearing cap, air inlet through hole in bearing cap and go out vent hole and all communicate with the circulation groove 3 on bearing shell body 1, by in the air inlet through hole in bearing cap, passing into air, air on bearing shell body 1 outer wall circulation groove 3 and axial hole 21 in the circulation, then from the vent hole that goes out on bearing cap, discharge, in whole process, the heat in bearing shell body 1 is taken away, reduced the temperature of bearing shell body 1, improve the working life of bearing shell.
