Abstract

The invention discloses a method for preparing gear oil, and belongs to the technical field of lubricating oil. According to the preparation method, easily biodegradable long-chain fatty acid oleic acid and organism forming components of amino acids are used as raw materials for preparing an amino acid type biodegradation promoter with a structure similar to a natural amino acid lipid body, the thermal stability is good, and the amino acid type biodegradation promoter cannot decompose or degenerate; on the other hand, a synthesized additive can improve the anti-rust property of gears, and theadditive covers the metal surfaces of the gears, so that oxygen, moisture or other corrosive substances in the air can be isolated to a certain extent. The invention solves the problems that existingcommon gear oil is not prominent in the abrasion-resistant effect of gears, gear oil has a good effect is added with fluorides which can pollute the environment, the base oil of gear oil has poor oxidation stability and poor low-temperature fluidity, the oil easily deteriorates, and the gear oil is corroded and abraded.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil, and in particular relates to a preparation method of gear oil. Background technique [0002] Gear oil mainly refers to the lubricating oil of transmission and rear axle. There are differences between it and engine oil in the conditions of use, its own composition and performance. Gear oil mainly plays the role of lubricating gears and bearings, preventing wear and corrosion, and helping gears to dissipate heat. Gear transmission is one of the most important transmission methods in mechanical transmission. The gear transmission motion and power are completed by the meshing of the tooth surfaces of the gears. During this period, friction will inevitably occur. In order to maintain the service life of the gear mechanism, the meshing tooth surfaces need to be lubricated with lubricating oil. , Lubricating oil forms an adsorption film and a reaction film on the tooth surface to reduce the fr...
