  • Patent number: 9347016
    Abstract: Provided is a micropitting corrosion resistant industrial gear lubricant composition, comprising: (A) at least a highly refined mineral oil, or synthetic oil or any combination of the above components; (B) at least a micropitting corrosion resistant additive; (C) at least an anti-wear additive; (D) at least a metal passivation additive; and (E) at least an anti-oxidation additive. The lubricant composition has excellent high and low temperature performance and meets 68, 100, 150, 220, 320, 460 and 680 industrial gear oil viscosity level requirement. The lubricant composition has excellent micropitting corrosion resistance, anti-wear performance and anti-oxidation performance, passes FVA 54 micropitting corrosion resistant test, FAG FE-8 bearing wear test and SKF EMCOR bearing corrosion test, and is suitable for many large-scale industrial transmission gears and some automobile transmission gears, especially suitable for a gear transmission system for wind power generation.
