Abstract
The invention relates to an alloy automobile bearing which comprises the following components by weight percent: 18-33% of Zn, 8-15% of Al, 1.2-3% of Cr, 0.6-1.2% of Mo and the balance of Cu. According to the need, 1-3% of MoS2 and 12-25% of Fe can be added into the alloy automobile bearing. According to the alloy automobile bearing, the Cu and the Zn are taken as base components, and the Al is added to into the bearing, so that the strength and the plasticity of the bearing can be improved, and the weight of the bearing is lightened to a certain extent; the Cr and the Mo are added into the bearing, so that the strength, the hardness, the wear resistance and the corrosion resistance of the bearing are improved; the MoS2 has a relative good lubricating property, so that the friction and wear properties of the bearing can be improved; in order to further divide the product orientation, a certain amount of Fe powder is added into the bearing, and the adding quantity of the Cu is correspondingly reduced, so that the aim of reducing the cost of the bearing can be achieved.
Description
Technical field
The invention belongs to automobile bearing, be specifically related to a kind of alloy automobile bearing.
Background technology
Bearing, as the vitals of each transmission portion of automobile, usually uses alloy manufacture, has vital role and meaning to the stability of automobile and security etc.Especially along with the development of automobile industry, automotive performance improves constantly, the quality of each parts and performance requriements are also improved constantly, wherein especially tackle variously to run up, important subject that the stability of high loaded process lower bearing, wear resistance, oilness and security etc. become current automobile industry more.Traditional copper aluminum series alloy automobile bearing, although have higher intensity and wear resistance, because its difficulty of processing is comparatively large, makes its applying in industry be restricted.Meanwhile, traditional copper base alloy automobile bearing cost is higher, and on the basis ensureing bearing property, how to find the equivalent material of low cost, be also one of important research direction of automobile industry.
Summary of the invention
One object of the present invention is the alloy proportion scheme by a kind of optimization, provides a kind of and has possessed better stability, wear resistance and the automotive alloys bearing compared with the long life.Also replacing with Fe by reducing part Cu content on the basis ensureing fundamental property simultaneously, production cost can be reduced to a certain extent, improving enterprise competitiveness.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of alloy automobile bearing, is made up of the component of following weight proportion: Zn:18-33%, Al:8-15%, Cr:1.2-3%, Mo:0.6-1.2%, Cu: surplus.
Preferably, described bearing is made up of the component of following weight proportion: Zn:22-27%, Al:10-12%, Cr:1.5-1.8%, Mo:0.8-1%, Cu: surplus.
Further, described bearing also added MoS
2: 1-3%.
Further, described bearing also added Fe:12-25%.
Various raw material of the present invention is conventional commercial powder metallurgy raw material, and manufacture method adopts conventional powder metallurgical technique.
The invention has the beneficial effects as follows: in alloy automobile bearing of the present invention, component based on Cu and Zn, with the addition of Al and play the effect increasing bearing strength and plasticity, bearing weight can also be alleviated to a certain extent simultaneously; Cr and Mo added mainly plays the intensity, hardness, wear resistance and the erosion resistance that improve bearing; MoS
2there is good lubricating property, the friction and wear behavior of bearing can be improved; In order to Further Division product orientation, can also add a certain amount of Fe powder and the addition of corresponding reduction Cu, reach the object reducing bearing cost thus, under the prerequisite ensureing bearing fundamental property, the addition of Fe should control at 12-25%.
Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.
