Abstract

The invention discloses a lubricating oil for gears. The lubricating oil is prepared from modified base oil, succinate, diethylenetriamine penta(methylene phosphonic acid), octyl diphenylamine, sorbitol, nano copper powder, C12 dibasic acids, beta-sitosterol, cholesteryl nonanoate, ethanediol amide cocoate and auxiliary additives. The lubricating oil for gears has the characteristics of favorable oxidation resistance, favorable corrosion resistance, favorable rust resistance, favorable wear resistance, favorable anti-friction property, high torque, favorable high-temperature stability, favorable demulsibility, long oil change period, favorable biodegradability and lower price than the traditional lubricating oil, and reduces the emissions of waste oil, waste gas and particles. The lubricating oil has the advantages of favorable viscosity, favorable lubricating property, favorable cooling property, excellent viscosity-temperature characteristics, high viscosity index, low condensation point and high flash point, and well reduces the friction between gear pairs.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a lubricating oil for gears. Background technique [0002] Bearing lubricating oil is lubricating oil used on bearings to lubricate, cool down, resist pressure, and prolong the life of bearings. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. Base oil is refined from crude oil, generally alkanes (linear, branched, multi-branched), cycloalkanes (monocyclic, bicyclic, polycyclic), aromatics (monocyclic aromatics, polycyclic aromatics), cycloalkylaromatics And oxygen-containing, nitrogen-containing, sulfur-containing organic compounds and non-hydrocarbon compounds such as colloids and asphaltenes.
