Problems solved by technology

Since the gear load is generally above 490 MPa (MPa), and the hyperbolic tooth surface load is as high as 2942MPa, in order to prevent the oil film from breaking and causing tooth surface wear and abrasion, anti-wear agents are often added to the gear oil, but the anti-wear performance is arbitrary. not ideal

Abstract

The invention relates to lubricating oil for gears. The lubricating oil comprises, by weight, 50-70 parts of 650SN base oil, 5-15 parts of 250BS base oil, 15-25 parts of 150BS base oil, 3-6 parts of polyvinyl ether, 4-8 parts of calcium alkylbenzene sulfonate, 3-7 parts of ethylene-propylene copolymer, 1-4 parts of sodium sulfite, 4-6 parts of sodium dodecyl benzene sulfonate, 7-11 parts of trichloromethane, 2-6 parts of methyl benzoate, 3-5 parts of antioxidant, 2-4 parts of triethanolamine, 1.5-3 parts of dispersing agent, 0.2-1.5 parts of extreme pressure anti-wear agent and 1.0-3.5 parts of metal deactivator, wherein the metal deactivator contains benzotriazole or thiadiazole. The lubricating oil is good in wear resistance, capable of bearing high temperature generated by the high-speed rotation and the meshing of the gears, good in cooling performance, high in extreme pressure resistance, and suitable for engines and large machinery.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a special lubricating oil for gears. Background technique [0002] Gear oil is an important lubricating oil prepared mainly from petroleum lubricating oil base oil or synthetic lubricating oil, with the addition of anti-wear agents and oiliness agents. Used in various gear transmissions to prevent tooth surface wear, abrasion, sintering, etc., prolong its service life and improve the efficiency of power transmission. Gear oil should have good anti-wear, load resistance and suitable viscosity. Since the gear load is generally above 490 MPa (MPa), and the hyperbolic tooth surface load is as high as 2942MPa, in order to prevent the oil film from breaking and causing tooth surface wear and abrasion, anti-wear agents are often added to the gear oil, but the anti-wear performance is arbitrary. Not ideal. Contents of the invention [0003] In view of the above-mentioned problems in the prior ar...
