Abstract

The invention provides a preparation method of bearing lubrication oil. The preparation method of the bearing lubrication oil comprises the following steps: step one, taking poly-alpha-olefin, tetramethylolmethane and polyalkylene glycol, and uniformly stirring and mixing to prepare base oil; step two, taking diethylenetriaminepenta acid, succinate, di-alkenyl succinimide, cerium fluoride nanoparticles, poly-alcoxyl polyphenol, alkyl diphenylamine, butyl-octyl diphenylamine and laurylene ester succinate, uniformly stirring and mixing to obtain a mixture A, and then adding the mixture A into the base oil and uniformly stirring to obtain a mixture B; step three, simultaneously stirring and adding cholesterol into the mixture B, then heating to 83 to 88 DEG C and preserving the heat for 2 to 5 hours; cooling the mixture to the room temperature and prepare the bearing lubrication oil. The bearing lubrication oil is excellent in performance; the abrasion resistance can be improved by over 30%; the flashing point reaches 240 DEG C; the viscosity index is 105 to 125; the acid value is 0.08 to 0.13mg of KOH / g.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a preparation method of lubricating oil for bearings. 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 roller bear...
