Embodiment Construction

[0014] An aluminum-based composite bearing material with high resistance and stability, made of the following raw materials in parts by weight (kg): aluminum 85, copper 5, molybdenum 3, magnesium 1, silicon 0.5, polytetrafluoroethylene powder 3, disulfide Molybdenum 0.8, stearic acid 2, methyl cellulose 0.6, graphite 1, lime paste 1.5, boron nitride 0.4, asbestos wool 1, oleic acid amount;

[0015] The aluminum-based composite bearing material with high resistance and stability is prepared by the following specific steps:

[0016] (1) Pour aluminum, copper, molybdenum, magnesium and silicon powder into a mortar, grind and mix evenly, then add the mixed powder to a ball mill, add an appropriate amount of alcohol for wet ball milling, and the ball milling speed is 20 rpm, After ball milling for 1 hour, the mixed powder is added to a vacuum oven, dried at 70°C and placed for subsequent use;

[0017] (2) Mix oleic acid and graphite into an ultrasonic oscillator to disperse evenly...

Abstract

The invention discloses an aluminum-based composite bearing material high in high-resistance-stability. The aluminum-based composite bearing material is prepared from, by weight, 85-90 parts of aluminum, 5-8 parts of copper, 3-4 parts of molybdenum, 1-2 parts of magnesium, 0.5-1 part of silicon, 3-4 parts of polytetrafluoroethylene powder, 0.8-1.5 parts of molybdenum disulfide, 2-3 parts of stearic acid, 0.6-1 part of methylcellulose, 1-1.5 parts of graphite, 1.5-2 parts of lime putty, 0.4-0.5 part of boron nitride, 1-2 parts of asbestos wool and a proper amount of oleic acid. The material is prepared through a powder metallurgy method, the technique is simple, operation is easy, the material cost is reduced, the material is good in mechanical property and high in high-resistance-stability, the part precision is high, molding is good, and the material is worthy of popularization.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to an aluminum matrix composite bearing material with high resistance and stability. Background technique [0002] Metal sintered oil-impregnated bearings are a kind of sintered material made by powder metallurgy process with metal powder as raw material. Metal sintered oil-containing products are inherently porous, and have the advantage that the number, size and distribution of voids can be freely adjusted during the manufacturing process. Sintered metal oil-impregnated bearings have been widely used in many fields such as automobiles, household appliances, transportation machinery, agricultural machinery, instruments and meters. Sintered metal oil-impregnated bearings mainly used in modern industry can be divided into copper-based, iron-based, copper-iron-based, etc. according to the base material. Aluminum is one of the most widely distributed elements in the earth's...
