Abstract
The utility model discloses a bearing bush with a heat rejection effect, and relates to the technical field of bearing bushes. The bearing bush comprises two half terete bearing bush bodies, wherein an oil filling hole (11) is arranged on the wall above the bearing bush body (1), an inner wall of the bearing bush body (1) is provided with a ring-shaped oil groove (12), and one end of the oil filling hole (11) is communicated with the ring-shaped oil groove (12); multiple convex half rings (2) are formed on the outer wall of the bearing bush body (1), and centers of the multiple convex half rings (2) are arranged on a central shaft line of the bearing bush body (1); and a circulating groove (3) is formed between each two convex half rings (2), multiple axial through holes (21) are formed on the half rings (2), and the axial through holes (21) are communicated with the circulating grooves (3) on the two sides of the half rings (2). The bearing bush can rapidly carry out heat rejection in service, and the service life of the bearing bush is prolonged.
Description
(1) technical field
The utility model relates to the bearing shell technical field, and what be specifically related to is a kind of bearing shell with radiating effect.
(2) background technique
Bearing shell is the sliding bearing important component part, on its wall oil hole is arranged, there is annular oil groove the 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 be excessive, excess Temperature, lubricant oil exists the factors such as impurity or viscosity be unusual to cause tile kilning, and sliding bearing has just damaged behind the tile kilning, existing bearing shell its just by be provided with the space in bush seat, bearing shell is installed in the bush seat, thereby reduce the operating temperature of bearing shell, its DeGrain, poor radiation.
(3) model utility content
The purpose of this utility model is exactly the deficiency for prior art, and a kind of bearing shell with radiating effect 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 bearing shell with radiating effect, comprise two half-terete bearing shell bodies, 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, form the semicircular ring of a plurality of projections on the outer wall of described bearing shell body, the center of circle of a plurality of semicircular ring is on the central axis of bearing shell body; Be circulation groove between per two semicircular ring; Be formed with a plurality of axial holes on the semicircular ring, through hole communicates with the circulation groove of the both sides of semicircular ring.
Be formed with eight axial holes on described each semicircular ring, the circulation groove axial length between per two semicircular ring is identical.
Form the semicircular ring of three projections on the outer wall of described bearing shell body, 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 forms the semicircular ring of a plurality of projections by the outer wall at the bearing shell body, be circulation groove between per two semicircular ring, be formed with a plurality of axial holes on the semicircular ring, through hole communicates with the circulation groove of the both sides of semicircular ring, 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.
(4) description of drawings
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.
Among the figure: 1, bearing shell body; 11, oil hole; 12, annular oil groove; 13, gulde edge; 2, semicircular ring; 21, through hole; 3, circulation groove;
(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 that Fig. 1 is to shown in Figure 3, a kind of bearing shell with radiating effect, comprise two half-terete bearing shell bodies 1, 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, form the semicircular ring 2 of a plurality of projections on the outer wall of described bearing shell body 1, and the center of circle of a plurality of semicircular ring 2 is on the central axis of bearing shell body 1; Be circulation groove 3 between per two semicircular ring 2; Be formed with a plurality of axial holes 21 on the semicircular ring 2, through hole 21 communicates with the circulation groove 3 of the both sides of semicircular ring 2.
Be formed with eight axial holes 21 on described each semicircular ring 2, circulation groove 3 axial lengths between per two semicircular ring 2 are identical.
Form the semicircular ring 2 of three projections on the outer wall of described bearing shell body 1, 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 the bearing cap, air inlet through hole in the bearing cap and go out vent hole and all communicate with circulation groove 3 on the bearing shell body 1, by passing into air in the air inlet through hole in the bearing cap, air on bearing shell body 1 outer wall circulation groove 3 and axial hole 21 in the circulation, then the vent hole that goes out from the bearing cap is discharged, in whole process, the heat in the bearing shell body 1 is taken away, reduced the temperature of bearing shell body 1, improve the working life of bearing shell.
Claims (3)
