Lubricating oil used for bearings, and preparation method thereof

Abstract

The invention discloses a lubricating oil used for bearings. The lubricating oil comprises, by weight, 60-75 parts of mineral base oil, 2-5 parts of zinc dithiosulfate, 8-10 parts of chlorinated paraffin, 6-8 parts of diallyl alkyl phosphate, 3-5 parts of hydroxyl silicone oil, 1-3 parts of diallylalkyl phosphate, 2-5 parts of polyalkoxy polyphenol, 4-9 parts of alkyl diphenylamine, 2-6 parts of butyloctyl diphenylamine, 5-12 parts of diethylene triamine penta(methylenephosphonic acid), 4-9 parts of dialkenyl succinimide, 10-15 parts of modified acrylic acid, 2-5 parts of sodium citrate, 3-6 parts of succinimide, 4-10 parts of chlorinated polyethylene, 10-14 parts of succinate ester, 12-20 parts of dodecenylsuccinic acid and 3-9 parts of anhydrous ethanol. Compared with lubricating oils in the prior art, the lubricating oil disclosed in the invention has the advantages of great reduction of the friction force of the bearings, reduction of damages of the bearings in the use process, reduction of temperature rising in the use process, prolong of the service life of the bearings, and realization of no generation of toxic substances in the use process, and can prolongs the life of the bearings by 60% or above.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a lubricating oil for bearings and a preparation method thereof. Background technique [0002] Bearing is an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimension, vibration and noise are larger, and the price is also higher. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling elements and cages; according to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and ...
