Abstract
The present invention relates to an alloy mainly used for manufacturing a low-speed and heavy-load bearing shell or a shaft sleeve matched with a hard shaft, and the alloy is also suitable for manufacturing worn parts, such as embedded sheets, to replace common bronze parts. The alloy uses a zinc-aluminum series as a base, and a small amount of alloy elements are added; hard material particles are distributed on the base, and the number of soft phases is not less than 10%; the size, the pattern and the distribution of the material particles are controlled. The mixtures are smelted by a resistance furnace, and are formed by metal moulds, sand moulds, centrifugal casting or isothermal extrusion. The friction coefficient and the shaft abrasion quantity of the alloy are equivalent to or are slightly smaller than those of ZQSn6-6-3 bronze, the abrasive resistance of the alloy is higher 2 to 4 than that of the ZQSn6-6-3 bronze, and the cost is less than 1/2 of that of the bronze. The present invention has the advantages of no pollution, easy cutting and low energy consumption, and is suitable for individual production and bulk production.
Description
The invention belongs to a kind of high-abrasive material, be mainly used in * and make bearing shell or the axle sleeve that is complementary with hard axle, also can manufacture town's sheet, other part of guide plate etc. and so on wearing and tearing.
The bearing shell, the axle sleeve that bear heavy duty are indispensable fricting couple piece in the machine drive mechanism, the material that this fricting couple piece uses is so far still based on bronze material, to some engineering goods and these products during one's term of military service, bronze plain bearing, axle sleeve consumption are very big, because copper tin costs an arm and a leg, the military service phase is very short, brings direct and consequential damage also just considerable.Use the zinc alloy bearing materials to replace the * bearing materials, because the starting material source is abundant, cheap, technology is simple, outstanding advantage such as less energy consumption, once occurred and similar patent of the present invention such as JP58-52454, J59001-647A, GB918390 etc., facts have proved, they are all perfect not to the utmost, if any anti-* own, but mill axle is serious; Perhaps self is wear-resisting, and frictional coefficient is big, and shortcomings such as noble element Sn have perhaps been adopted in temperature rise, so that zinc base bearing fails extensively to adopt.
The present invention is directed to and hard axle paired bearing shell, axle sleeve, overcome the shortcoming of existing zinc alloy, design, prepare a kind of novel bearing shell or axle sleeve of being applicable to, particularly at low speed, fully loaded transportation condition descends the bearing shell of work, the zinc alloy high-abrasive material of axle sleeve, can in very large range replace bearing shell, the axle sleeve of bronze material.
The present invention is to be base with zinc-aluminium, adds elements such as a spot of copper, magnesium, manganese, titanium, rare earth, and by control * casting process and other technology, the metallographic microstructure of alloy is a polyphase structure, the disperse wear-resisting hard point that distributing on the matrix.Wherein, * phase constitution quantity accounts for more than 10 of sum.The chemical ingredients of alloy is (by weight percentage); Al:8～31(optimum content is 20～31%); Cu:0.5～3.5(optimum content is: 0.8～3.1%) Mg, Mn, Ti, RE constituent content between 0.02～2.0% (optimum content is 0.04～1.8%) respectively.Alloy can be cast bar, by the isothermal extrusion molding, also can be in metal mold, graphite mould, sand mold casting, or centrifugal casting.
The present invention generally acknowledges that with external ZA27 that performance (comprising bearing property) is best and relevant patent compare, frictional coefficient little (with the axle coupling of quenching), and the mill axle is light, the wear resistance height, compare with bronze ZQSn6-6-3 commonly used, its frictional coefficient and grinding spindle amount quite or lower slightly, but wear resistance is higher 2～4 times than ZQSn6-6-3, and cost is less than 1/2nd of ZQSn6-6-3, essentially no pollution, easily cutting can be by waiting warm-extrusion forming, energy consumption is low, and the small quantities of or specialized production of single-piece all suits.
Claims (2)
1, a kind of Zi-Al-Co-Mn alloy for bearing is base with the element zinc, adds that other is elementary composition, feature of the present invention is that to account for weight alloy per-cent be 8-31% to Aluminum in Alloy, it is 0.5-3.5% that copper accounts for weight percent, and magnesium, manganese, titanium, ree content are respectively 0.02-2.0%, and all the other are zinc.
2, the described bearing metal of claim 1, its optimal components be in following scope, aluminium 20-31%, and copper 0.8-3.1%, magnesium, manganese, titanium, rare earth element are 0.04-1.8%, all the other are zinc.
