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
The present invention relates to a kind of lubricating oil, be specifically related to a kind of gear special lube.
Background technology
Gear oil is based on petroleum oil base oil or ucon oil, adds a kind of important lubricating oil of anti-wear agent and oiliness improver modulation.For various wheel gearing, to prevent tooth surface abrasion, scratch, sintering etc., extend its work-ing life, improve transmitted power efficiency.Gear oil should have good wear-resistant, withstand load performance and suitable viscosity.Because gear loading is general all more than 490 MPas (MPa), and hyperbolic line flank of tooth load is more up to 2942MPa, for preventing rupture of oil film from causing tooth surface abrasion and scratch, often adds anti-wear agent in gear oil, but to appoint be not very desirable to abrasion resistance.
Summary of the invention
For the problems referred to above that prior art exists, the object of the invention is: provide one to have good resistance to abrasion, and high-speed gear rotation can be born, the lubricating oil of the high temperature that engagement produces.
For achieving the above object, the present invention adopts following technical scheme: a kind of gear special lube, it is characterized in that: the component comprising following mass fraction: 650SN base oil 50-70 part, 250BS base oil 5-15 part, 150BS base oil 15-25 part, polyvinyl ether 3-6 part, alkyl benzene calcium sulfonate 4-8 part, ethylene-propylene copolymer 3-7 part, S-WAT 1-4 part, Sodium dodecylbenzene sulfonate 4-6 part, trichloromethane 7-11 part, methyl benzoate 2-6 part, antioxidant 3-5 part, trolamine 2-4 part, dispersion agent 1.5-3 part, extreme pressure anti-wear additives 0.2-1.5 part, metal passivator 1.0-3.5 part.
As optimization, described metal passivator is for containing benzotriazole or thiadiazoles.
Relative to prior art, tool of the present invention has the following advantages: lubricating oil of the present invention has good resistance to abrasion, and can bear high-speed gear rotation, the high temperature that engagement produces, have good cooling, anti-extreme pressure is very capable simultaneously, be suitable for engine, big machinery.
