Abstract

The present invention is the recipe of lubricant oil for motor gear box. The present invention features that the lubricant oil consists of: lithium dodecahydroxyl stearate 12-16 wt%, lithium salicylate 2.6-3.3 wt%, benzaldehyde-2-naphthylamine 0.9-1.1 wt%, barium petroleum sulfonate 1.7-2.3 wt%, molybdenum disulfide 6.2-7.6 wt%, ammonium fluorothiobarate 2.7-3.3 wt% and glycoside polyol 9.2-10.5 wt% except synthetic base oil. The lubricant oil has the functions of reducing gear meshing operation noise and prolonging the service life of gears, and can also repair rough metal surface of gears.

Description

technical field [0001] The invention relates to a formula of lubricating oil, in particular to a formula of lubricating grease used in motor gearboxes. Background technique [0002] In recent years, the application range of lubricating oil has become wider and wider, and new varieties of lubricating oil have also come out continuously. For example, the patent "high-performance lubricating oil" has been published. , compressor oils and lubricating oils for other purposes, which are characterized by a well-balanced comprehensive balance of anti-wear and anti-rust properties, said lubricating oils are based on high-quality basic materials including a main part of the main hydrocarbon-based raw material such as PAO and auxiliary raw material components Feedstock, said auxiliary feedstock components are preferably long-chain alkylated aromatic hydrocarbons such as alkylnaphthalene. Synergistic combination of additives comprising substituted triazoles such as benzotriazole or sub...
