Abstract

The utility model discloses a plastic bearing with a copper-alloy plate net, aiming at providing the plastic bearing with the copper-alloy plate net which has advantages of light weight, non rust and having no necessity of adding lubricant. The plastic bearing comprises a copper-alloy net and a shaft sleeve which is enclosed by plastics embedded in meshes of the copper-alloy net and on the surfaces of both sides, wherein a joint close is disposed on the surface of the sleeve, and the plastic bearing is characterized in that the copper-alloy net is the copper-alloy plate net. The copper-alloy plate net is made of a copper-alloy plate through stamping and stretching and achieves structural stability. Non-metallic anti-friction material is rolled on the copper-alloy net surface and then solidified to shape by sintering and rolling in order to obtain a composite plate with the copper-alloy plate net as a framework and the non-metallic anti-friction material as a main body, and then is cut into small pieces according to the bearing size, and finally rolled, shaped and processed, as if an ordinary oil-free bearing, into the shaft sleeve or a flanging shaft sleeve. The plastic bearing with the copper-alloy plate net is more used in the automotive industry, office appliances and other occasions, and has advantages of light weight, non-noise usage, low friction coefficient and having no necessity of adding lubricant.

Description

The plastic bearing of band Cuprum alloy expanded metals

Technical field

The utility model relates to sliding bearing, relates in particular to a kind of plastic bearing with the Cuprum alloy expanded metals.

Background technique

Chang Yong Cuprum alloy silk screen plastic bearing in the market, be with Cuprum alloy silk screen and the axle sleeve that plastics surrounded that is embedded in the Cuprum alloy silk screen mesh, its Cuprum alloy silk screen is to adopt the copper wire mesh grid, exists easy tensile buckling and defective such as wire drawing is arranged, and workmanship is difficult to be controlled.

Summary of the invention

The purpose of this utility model provides a kind of in light weight, plastic bearing that can not get rusty, not need to add the band Cuprum alloy expanded metals of oiling agent.

In order to achieve the above object, structure technology scheme of the present utility model is: comprise the Cuprum alloy net and be embedded in the axle sleeve that plastics surrounded that reaches both side surface in the Cuprum alloy net meshe, on the surface of axle sleeve one joint close is arranged, it is characterized in that described Cuprum alloy net is the Cuprum alloy expanded metals.

The plastic bearing of the band Cuprum alloy expanded metals of said structure, used Cuprum alloy expanded metals is to be formed by the copper alloy plate punching stretch, structural stability, the integrated type expanded metals has been avoided the silk screen distortion and the defective of reeling off raw silk from cocoons.Nonmetal antifriction material the copper alloy plate net surface is rolling, again through sintering, the rolling solidified forming that waits, make based on the Cuprum alloy expanded metals is the composite board of skeleton, nonmetal antifriction material, size according to bearing is cut into small pieces again, equally rolls, shaping, is processed into axle sleeve or flanger bearing bush by common oilless bearing.More in applications such as automobile industry, office accommodations, advantage is light weight, uses noise free, and friction factor is low, need not add oiling agent, and Cuprum alloy itself also is a kind of good antifriction metal material simultaneously.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing.

The utility model is rolling on the punching press and the Cuprum alloy expanded metals 1 that obtains that stretches with brass sheet or tin bronze plate as shown in Figure 1, sintering in mesh and both side surface be embedded with teflon or with its be the main body mixture 2 that adds other fillers compound plastic plate as shown in Figure 2, size according to bearing is cut into small pieces again, equally roll by common no cunning dynamic bearing, shaping, be processed into axle sleeve such as the Fig. 3 that there be a joint close 3 on the surface, shown in Figure 4 or the band flange flange 4 axle sleeves, the opening 5 that V-arrangement is arranged on the flange, opening 5 bottoms link to each other as Fig. 5 with joint close 3, shown in Figure 6.Certainly, above-mentioned except with also coming punching press and stretching to obtain with other copper alloy plate brass sheet or the tin bronze plate manufactured copper alloy expanded metals 1.Except above-mentioned be that main body is added the mixture 2 of other fillers with teflon or with it, also can be with the plastics of other antifriction performances that have.

Claims
