Abstract

The invention discloses a bearing lubricating oil with good wear resistance and a preparation method thereof. The lubricating oil is mainly prepared from dialkenyl succinimide, modified acrylic acid,tricresyl phosphate, succinate, polyalkoxy polyphenol, chlorinated paraffin, oxidized rapeseed oil and benzotriazole. The bearing lubricating oil disclosed by the invention is excellent in performance, the wear resistance can be improved by 30% or above, the flash point reaches 240 DEG C, the viscosity index is 105-125, and the acid value is 0.08-0.13 mg KOH / g. Through metal compound nanoparticles, the friction coefficient is reduced, the wear is reduced, and a repairing layer with stable structure and excellent bearing capacity can be formed on the surface of a friction pair at the same time,so that the anti-friction performance and friction resistance are achieved. The friction is reduced and the wear resistance can be improved through the chlorinated paraffin.

Description

technical field [0001] The invention relates to a lubricating oil for bearings and a preparation method thereof, in particular to a lubricating oil for bearings with good wear resistance 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 divid...
