Technology solution of the present utility model is as follows:

A kind of sliding bearing with radiating effect, comprise two half-terete bearing shell bodies, bearing supports and be positioned at the bearing cap of bearing support top, bearing support and bearing cap are bolted to connection and two half-terete bearing shell bodies are clamped, the bearing shell body wall of top 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 two bearing shell bodies, form the semicircular ring of a plurality of projections, the center of circle of a plurality of semicircular ring is on the central axis of bearing shell body; Between every two semicircular ring, it is circulation groove; On semicircular ring, be formed with a plurality of axial holes, through hole communicates with the circulation groove of the both sides of semicircular ring; The semicircular ring outer wall is pressed against on the inwall of bearing support or bearing cap, on bearing cap, forms the air inlet through hole and goes out vent hole, air inlet through hole and go out vent hole and communicate with circulation groove.

Described air inlet through hole and go out the oil inlet hole both sides of vent hole at bearing cap, an end of air inlet through hole and the circulation groove of the bearing shell body of the top side that keeps left partly communicates, and an end that goes out vent hole partly communicates on the right side with the circulation groove of the bearing shell body of top.

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

On the outer wall of described bearing shell body, form the semicircular ring 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 of a plurality of projections on the outer wall at the bearing shell body, between every two semicircular ring, it is circulation groove, on semicircular ring, be formed with a plurality of axial holes, through hole communicates with the circulation groove of the both sides of semicircular ring, on bearing cap, form the air inlet through hole and go out vent hole, air inlet through hole and go out vent hole and communicate with circulation groove, by the air inlet through hole, enter into circulation groove and axial hole again from going out vent hole and bearing shell body and bearing support when air like this, in gap between bearing cap, flow out, the air flowed in whole process has been taken away a large amount of heat in the bearing shell body, reduce the temperature of bearing shell body, improve the working life of sliding bearing.

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 structural representation of the present utility model;

Fig. 3 is the structural representation of bearing shell body;

Fig. 4 is the side view of bearing shell body;

Fig. 5 is the perspective view of bearing shell body.

In figure: 1, bearing shell body; 11, oil hole; 12, annular oil groove; 13, gulde edge; 2, semicircular ring; 21, axial hole; 3, circulation groove; 4, bearing support; 5, bearing cap; 51, air inlet through hole; 52, go out vent hole; 53, oil inlet hole.

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 5, a kind of sliding bearing with radiating effect, comprise two half-terete bearing shell bodies 1, bearing support 4 and the bearing cap 5 that is positioned at bearing support 4 tops, bearing support 4 and bearing cap 5 are bolted to connection and two half-terete bearing shell bodies 1 are clamped, bearing shell body 1 wall of top 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 two bearing shell bodies 1, form the semicircular ring 2 of a plurality of projections, the center of circle of a plurality of semicircular ring 2 is on the central axis of bearing shell body 1, between every two semicircular ring 2, it is circulation groove 3, on semicircular ring 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 2, semicircular ring 2 outer walls are pressed against on the inwall of bearing support 4 or bearing cap 5, on bearing cap 5, form air inlet through hole 51 and go out vent hole 52, air inlet through hole 51 and go out vent hole 52 and communicate with circulation groove 3.
