AI Technical Summary

Problems solved by technology

Since the wheel hub bearing of the automobile rotates at high speed, the speed is high, and because of the high temperature, the general lubricating grease is easy to cause volatilization, which leads to the reduction of the use effect, and cannot play a good lubrication and cooling effect.

Abstract

Improved automobile hub bearing lubricating grease is prepared from the following raw materials in parts by weight: 6-11 parts of ethyl acetate, 2-6 parts of pentaerythritol, 7-9 parts of ethylene glycol monobutyl ether, 1-4 parts of alkyl benzene sulfonic acid, 3-6 parts of dialkyl benzene sulfonic acid, 5-10 parts of thiadiazole derivative, 3-6 parts of trimethylolpropane, 4-7 parts of acrylic acid glyceride, 6-8 parts of sorbitan monooleate, 4-9 parts of FEVE fluorocarbon resin, 2-7 parts of hydrogenated dimeric acid, 1-4 parts of an anti-rusting agent, 2-6 parts of di-iso-octyldiphenylamine, 4-6 parts of methyl acrylate, 15-24 parts of base oil and 1-3 parts of a thickening agent. The improved automobile hub bearing lubricating grease provided by the invention has the benefits that good high-temperature resistance and anti-pressure ability are achieved, a lubricating oil film can be formed and frictional force is greatly reduced.

Description

technical field [0001] The invention relates to an improved lubricating grease for automobile hub bearings. Background technique [0002] Automobile hub bearing grease is made of semi-synthetic lubricating oil thickened with complex soap, and added with structure improver and anti-oxidant additives. Grease is suitable for the lubrication of various bearings, gears, chains and other transmission mechanical parts under high and low temperature; or it is suitable for the lubrication of engineering machinery, automobiles, motors, transmission mechanisms and other mechanical equipment that work outdoors in cold areas. Since the wheel hub bearing of the automobile rotates at high speed, the speed is high, and because of the high temperature, the general lubricating grease is easy to cause volatilization, which leads to the reduction of the use effect, and cannot play a good lubrication and cooling effect. Contents of the invention [0003] In view of the deficiencies in the pri...
