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 a special gear lubricating oil high in oxidation resistance. The special gear lubricating oil is composed of, 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 alkyl benzene sulfonic acid, 3-7 parts of ethylene-propylene copolymer, 1-4 parts of sodium sulfite, 4-6 parts of sodium dodecyl benzene sulfonate, 2-6 parts of methyl benzoate, 0.7-2.5 parts of complex antioxidant, 2-4 parts of triethanolamine, 0.2-1.5 parts of extreme-pressure antiwear agent, 1.0-3.5 parts of metal deactivator, 1.0-3.0 parts of detergent and 1.5-3 parts of dispersing agent. The special gear lubricating oil has the advantages of excellent wear resistance, capability of bearing high temperature generated by high-speed gear rotation and engagement, excellent cooling performance, high extreme pressure resistance and applicability to engines and large machines.

Description

technical field [0001] The invention relates to a lubricating oil, in particular to a special lubricating oil for gears with good oxidation resistance. 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-men...
