Embodiment 1

[0028] Total synthesis of the present invention, one kind of the anti-wind micropitting gear oil composition, the wind gear oil composition in percentage by mass, extreme pressure agents comprising 1%, 0.5% antiwear agent, 0.5% antioxidant, rust inhibitor 0.1%, 0.1% metal deactivator, demulsifier 0.1%, 0.02% antifoaming agent, the remainder being base oil.

[0029] The base oil and ester oil is a mixture of poly α-olefin based base oil, wherein the poly-α-olefin base oil excellent performance using a mixture of low viscosity and high viscosity PAO8 PAO40 control both the mass ratio of 8: 75, so that the base oil has a higher viscosity index, and also poly-α-olefin oil so that the wind power gear thermal evaporation loss is small; ester-based base oil with a saturated polyol esters can be made with a wind turbine gearbox oil in the seal materials . Poly α-olefin embodiment quality base oil and ester base oil of the present embodiment is a ratio of 7: 1, the ratio of poly-α-olefin r...

Embodiment 2

[0034] A full-forming anti-microprophoric wind power gear composition, the wind electrical gear oil composition, comprising 1%, anti-wear agent 0.8%, anti-oxygen repellent agent, anti-oxygen repellent agent 0.1%, metal reduction agent 0.1%, anti-emulsifier 0.1%, antifurbance agent 0.03%, and the balance is base oil.

[0035] The base oil is a mixture of poly alpha olefin base oils and ester base oils, wherein the polyethylene olefin base oil uses a mixture of low viscosity of low viscosity of low viscosity, and controls the mass ratio of both: 8: 75, so that the base oil has a higher degree of viscosity, and the poly alpha olefin also causes the heat-evaporation loss of the wind power tooth oil; the ester base oil is saturated with a saturated polyol ester, and the oil and wind power gearbox can be used. Allow. In this example, the mass ratio of the poly alpha olefin base oil and the ester base oil is 7: 1, and the ratio of the polyethylene olefin base oil and the ester base oil i...

Embodiment 3

[0040] A full-forming anti-micropod wind power gear composition, which comprises 1%, anti-wear agent 2%, an antioxidant, 0.5% antioxidant, anti-oxygen repellent 0.1%, metal reduction agent 0.1%, anti-emulsifier 0.3%, antifurbance agent 0.03%, and the balance is based.

[0041] The base oil is a mixture of poly alpha olefin base oils and ester base oils, wherein the polyethylene olefin base oil uses a mixture of low viscosity of low viscosity of low viscosity, and controls the mass ratio of both: 8: 75, so that the base oil has a higher degree of viscosity, and the poly alpha olefin also causes the heat-evaporation loss of the wind power tooth oil; the ester base oil is saturated with a saturated polyol ester, and the oil and wind power gearbox can be used. Allow. In this example, the mass ratio of the poly alpha olefin base oil and the ester base oil is 7: 1, and the ratio of the polyethylene olefin base oil and the ester base oil is reasonably controlled, and the additive can be ...

Abstract

The invention discloses a fully synthetic anti-micropitting wind power gear oil composition and a preparation method thereof, belonging to the technical field of lubricating oil. The present invention comprises 1-5% of extreme pressure agent, 0.5-3% of anti-wear agent, 0.5-3% of antioxidant, 0.1-2% of anti-rust agent, 0.1-1% of metal deactivator, anti-corrosion Emulsifier 0.1-0.5%, anti-foaming agent 0.01-0.1%, and the balance is base oil; the base oil is a mixture of polyalphaolefin base oil and ester base oil, polyalphaolefin base oil and ester base oil The mass ratio is 7‑10:1. The composition of the present invention is used in the gear box of wind power equipment. The evaporation loss of the fully synthetic oil is small, and it can be used for a long time under harsh working conditions and weather conditions. It has the advantages of good abrasiveness, good low temperature fluidity, and good oxidation stability; and polyalphaolefin and esters are used as base oils to ensure high viscosity index and good shear stability of gear oils and increase the service life of gear oils.

Description

Technical field [0001] Technical Field The present invention relates to lubricants, and more particularly, relates to a total synthesis of the anti-wind micropitting gear oil composition and preparation method. Background technique [0002] Wind power as a renewable energy source, in the past 10 years has been rapid development. Despite the rapid development of wind power industry, but the performance of wind turbines is unsatisfactory. Survey shows that the current power generation efficiency than the design value of wind farms average about 10% lower, and 50% of downtime related to the main gearbox. Since the failure of the gearbox of the wind machine costs 15% to 20%, and therefore to select the appropriate gear oil to ensure stable and efficient operation of the wind turbine, power generation efficiency is of great significance. [0003] The main role of the gearbox oil is used to prevent damage to the bearings, to avoid loss of viscosity or alter, inhibit foam generation, a ...
