Embodiment Construction

[0014] An aluminum-based bearing material with a small amount of wear, made of the following raw materials in parts by weight (kg): aluminum 85, zinc 5, niobium 3, magnesium 1, iridium 0.5, polytetrafluoroethylene powder 3, molybdenum disulfide 0.8, Stearic acid 2, methyl cellulose 0.6, graphite 1, mullite powder 0.7, polyamide wax micropowder 0.6, manganese sulfide 0.3, oleic acid amount;

[0015] The aluminum-based bearing material with a small amount of wear is prepared by the following specific steps:

[0016] (1) Pour aluminum, zinc, niobium, magnesium and iridium powder into a mortar and grind them evenly, then add the mixed powder into a ball mill, add an appropriate amount of alcohol for wet ball milling, 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, then add the mixed pow...

Abstract

The invention discloses an aluminum-based bearing material with low abrasion loss. The aluminum-based bearing material with low abrasion loss is prepared from the following raw materials in parts by weight: 85-90 parts of aluminum, 5-8 parts of zinc, 3-4 parts of niobium, 1-2 parts of magnesium, 0.5-1 part of iridium, 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, 0.7-1 part of mullite powder, 0.6-0.7 part of polyamide wax micro powder, 0.3-0.5 part of manganese sulfide and a proper amount of oleic acid. The bearing material prepared by the invention has the characteristics of excellent abrasion resistance and low friction force; meanwhile, the material is excellent in self-lubricating property and is a good material for preparing sliding bearings.

Description

technical field [0001] The invention relates to the technical field of powder metallurgy, in particular to an aluminum-based bearing material with less wear. 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 crust, and its content in the ...
