Abstract

A fully synthetic anti-micropitting wind power gear oil composition and a preparation method thereof are disclosed, belonging to the technical field of lubricating oil. The composition includes, by mass, 1-5% of an extreme pressure agent, 0.5-3% of anti-wear agent, 0.5-3% of an antioxidant, 0.1-2% of a rust inhibitor, 0.1-1% of a metal deactivator, 0.1-0.5% of an anti-emulsifier and 0.01-0.1% of an antifoaming agent, with the balance being base oil. The base oil is a mixture of poly(alpha-olefin) base oil and ester type base oil in a mass ratio of 7-10:1. The composition is used for gear casesof wind power equipment, evaporation loss of fully synthetic oil is low, and the composition can be used for long time in severe working conditions and climatic conditions, and has advantages of goodresistance to micropitting, high temperature detergency, good wear resistance, good low-temperature fluidity, good oxidation stability, and the like. The poly(alpha-olefin) and ester are adopted as base oil, thus ensuring a high viscosity index and good shear stability of the gear oil and prolonging the service lifetime of the gear oil.

Description

technical field [0001] The invention relates to the technical field of lubricating oils, and more particularly, to a fully synthetic anti-micropitting wind power gear oil composition and a preparation method thereof. Background technique [0002] As a renewable energy, wind energy has developed rapidly in the past 10 years. Despite the rapid development of the wind power industry, the performance of wind turbines is far from satisfactory. The survey shows that the current generation efficiency of wind farms is about 10% lower than the design value on average, and 50% of the shutdowns are related to the main gearbox. Since the failure of the gearbox increases the cost of the wind turbine by 15% to 20%, the selection of appropriate gear oil is of great significance to ensure the stable and efficient operation of the wind turbine and improve the power generation efficiency. [0003] The main functions of lubricating oil for gearboxes are to prevent bearing damage, avoid visco...
