Problems solved by technology
my country's wind turbines are mainly installed in Inner Mongolia, Gansu, Xinjiang and coastal areas rich in wind energy resources. The operating environment of wind power equipment is relatively harsh, with large temperature differences between day and night, and are easily affected by environmental factors such as humidity and seawatercorrosion. The long-term low-speed and heavy-load working conditions of the box itself can easily cause fatigue and wear of the gears, so the gears generally have micropitting
In fact, micropitting will lead to tiny cracks and pits on the tooth surface, causing noise and vibration, affecting the meshing accuracy of the gears, and in severe cases, it will cause broken teeth and affect the operating life of the overall equipment

Abstract
The invention relates to the technical field of wind driven generator gear oil, and especially relates to a micropittingcorrosion resisting wind powergear oil and a preparation method thereof. The micropittingcorrosion resisting wind powergear oil is prepared from, by mass, 45-65 parts of blended base oil, 5-10 parts of a micropittingcorrosion resisting complexing agent, 2-5 parts of an amine antioxidant, 1.5-2.5 parts of a metal deactivator, 0.5-2 parts of a pour pointdepressant and 0.5-2 parts of a defoaming agent, wherein the blend base oil comprises poly-alpha olefin, metallocene poly-alpha olefin, alkylnaphthalene and castor oil; and the micropitting corrosion resisting complexing agent comprises polyesterpolyol, poly ricinoleate and alcohol amine type boric acid ester. The gear oil provided by the invention is good in compatibility, can give full play to the functions of the components, has excellent micro pitting corrosion resistance through the synergistic effect of the different components, has high-temperature oxidation resistance, defoaming performance and low-temperature fluidity at the same time, can normally work in extreme high and low temperature climates, and prolongs the service life of equipment.
Description
technical field [0001] The invention relates to the technical field of wind turbine gear oil, in particular to an anti-micropitting wind turbine gear oil and a preparation method thereof. Background technique [0002] Under the dual pressure of energy crisis and environmental pollution, vigorously developing renewable resources has become a new development trend. As a successful case in the field of new energy, wind power has developed rapidly in recent years. my country's wind turbines are mainly installed in remote areas with rich wind energy resources such as Inner Mongolia, Gansu, Xinjiang and the coast. The operating environment of wind power equipment is relatively harsh, the temperature difference between day and night is large, and it is easily affected by environmental factors such as humidity and seawatercorrosion. The long-term low-speed and heavy-load working conditions of the box itself can easily cause gear fatigue wear. Therefore, micro-pitting corrosion is co...
