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 uses the alloy manufacturing usually as the vitals at each transmission position of automobile, and the stability of automobile and security etc. are had vital role and meaning.Especially along with the development of automobile industry, automotive performance improves constantly, quality and performance requriements to each parts also improve constantly, wherein especially tackle variously run up, stability, wear resistance, oilness and the security etc. of high loaded process lower bearing become the important subject of current automobile industry more.Traditional copper aluminum series alloy automobile bearing, although have higher intensity and wear resistance, because its difficulty of processing is larger, so that its applying in industry is restricted.Simultaneously, traditional copper base alloy automobile bearing cost is higher, how to seek cheaply equivalent material on the basis that guarantees bearing property, also is 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 possessed better stability, wear resistance and than the automotive alloys bearing of long life.Also on the basis that guarantees fundamental property, replace with Fe by reducing part Cu content simultaneously, can reduce production costs to a certain extent, improve enterprise competitiveness.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of alloy automobile bearing is comprised 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 comprised 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 has also added MoS
2: 1-3%.
Further, described bearing has also added Fe:12-25%.
Various raw material of the present invention is conventional commercial powder metallurgical raw material, and manufacture method adopts conventional powder metallurgical technique.
The invention has the beneficial effects as follows: in the alloy automobile bearing of the present invention,, added Al and played the effect that increases bearing strength and plasticity as basic components with Cu and Zn, can also alleviate to a certain extent bearing weight simultaneously; The Cr that adds and Mo mainly play intensity, hardness, wear resistance and the erosion resistance that improves bearing; MoS
2Have preferably lubricating property, can improve the friction and wear behavior of bearing; For the Further Division product orientation, can also add the addition of a certain amount of Fe powder and corresponding reduction Cu, reach thus the purpose that reduces the bearing cost, under the prerequisite that guarantees the bearing fundamental property, the addition of Fe should be controlled at 12-25%.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
Embodiment 1
A kind of alloy automobile bearing is comprised of the component of following weight proportion: Zn:18%, Al:12%, Cr:3%, Mo:0.6%, Cu: surplus.
