CN2583430Y - Corrugated bush - Google Patents

Abstract

The utility model discloses a bearing liner, the inner surface of which is provided with corrugation, and the utility model comprises a bearing liner body (1). The utility model is characterized in that the inner surface of the bearing liner body (1) is provided with a groove (2) which is in a corrugated shape. The utility model is a corrugated bearing which has large bearing area, benefits for keeping oil film pressure and is not easy to generate deflected abrasion; when the utility model is used, the utility model is in an assembly form same with the existing bearing liner; the utility model can be used for various materials of aluminium base and copper base bearing liner, the surface of the utility model can be conducted with ternary electroplating, or the utility model can be directly used without electroplating.

Description

A kind of Corrugated bush

Technical field:

The utility model relates to a kind of mechanical parts technical field, is a kind of bearing shell of inner surface belt ripple specifically.

Background technique:

Bearing shell is a kind of component of machine that generally adopts, bearing shell commonly used at present is watt body that a kind of machining is made, its loaded area is little, the load of bearing is low, be unfavorable for the maintenance of oil film pressure during use,, be unfavorable for that oil film forms if the fit up gap is excessive during assembling, the gap is too small, easily causes eccentric wear.

The model utility content:

The purpose of this utility model is intended to overcome the deficiency of above-mentioned prior art, and provide a kind of loaded area big, be beneficial to the ripple bearing that keeps oil film pressure, is difficult for causing eccentric wear.

In order to achieve the above object, the utility model is achieved in that a kind of Corrugated bush, and it comprises bearing shell watt body 1, is characterized in boring groove 2 at the internal surface of bearing shell watt body 1.

Corrugated bush of the present utility model, its described groove 2 is a bellows-shaped.

A kind of Corrugated bush described in the utility model, compared with the prior art have following good effect: 1, Corrugated bush is because the existence of ripple, increase the bearing shell loaded area effectively, both improved the bullet tension force of inner surface of bearing bush, decompose the explosive force of cylinder again effectively; 2, Corrugated bush has slowed down lubricant oil along the bearing shell axial flow velocity, helps keeping oil film pressure, thereby has strengthened the bearing capacity of Corrugated bush, more than the existing high 15MP of bearing shell of its fatigue ratio; 3, Corrugated bush is a plane at the crest place, the resistance and the wear rate of bent axle can not improve; 4, Corrugated bush assembling form with existing bearing shell on using is identical with the use type, need not change structure and size on the internal-combustion engine.

Description of drawings:

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

Fig. 2 is the cut-away view of Fig. 1;

Fig. 3 is the A portion enlarged view of Fig. 2;

Fig. 4 is the A portion enlarged view of Fig. 2.

Embodiment:

In order to understand better and to implement, describe a kind of ripple bearing liner of the utility model in detail below in conjunction with accompanying drawing.

Embodiment 1, and with reference to Fig. 1, Fig. 2, Fig. 3, bearing shell watt body 1 is made in machining, and bearing shell watt body 1 is made up of steel backing 3 and antifriction metal 4, bores groove 2 at bearing shell watt body 1 internal surface, and groove 2 is a bellows-shaped.

Embodiment 2, with reference to Fig. 1, Fig. 2, Fig. 4, bearing shell watt body 1 is made in machining, bearing shell watt body 1 is made up of steel backing 3 and antifriction metal 4, also can lead plating on antifriction metal 4, tin, copper, ternary alloy or other plating, bore groove 2 at bearing shell watt body 1 internal surface, groove 2 is a bellows-shaped.

A kind of Corrugated bush described in the utility model, the assembling form with existing bearing shell during use is identical, can be used for various aluminium base and copper base bearing shell materials, and the surface can be carried out ternary and electroplated, and also can directly use and need not to electroplate.

Claims (2)

1, a kind of Corrugated bush, it comprises bearing shell watt body (1), it is characterized in that establishing groove (2) at the internal surface of bearing shell watt body (1).

2,, it is characterized in that described groove (2) is bellows-shaped by the described a kind of Corrugated bush of claim 1.
