Abstract

The invention discloses high-performance fully-synthetic wind power gear oil. The wind power gear oil comprises base oil and additives, wherein the base oil is polyol ester, and the additives comprisean antioxidant, a demulsifying agent, a pour point depressant, an antirust agent, an extreme-pressure anti-wear agent, a detergent dispersant, a defoaming agent and a metal deactivator. The inventionalso provides a preparation method of the wind power gear oil. The preparation method comprises the following steps: carrying out an esterification reaction on polyol monoester and fatty acid to synthesize polyol ester, blending the polyol ester to obtain the base oil, adding the additives into the base oil, and conducting mixing to obtain the environment-friendly fully-synthetic wind power gearoil. According to the invention, the wind power gear oil has good compatibility with various additives and can be widely applied to a wind power gear oil tank; the gear oil has very long service lifeeven under severe working conditions; the high viscosity index and good shear stability of the gear oil are guaranteed; the lubricating requirement of a gear box used in a very wide viscosity range ismet; pitting corrosion can be effectively avoided or inhibited; and normal operation of a large heavy-duty mechanical gear transmission device is guaranteed.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a lubricating oil, in particular to a high-performance fully synthetic wind power gear oil and a preparation method thereof. Background technique [0002] Wind energy, as the most abundant clean renewable energy source in the world, has developed rapidly in the past few years. China is rich in wind energy resources and has a large demand for electricity, which has attracted more and more attention from all walks of life. To maintain continuous increase in power output, the key is to keep wind turbines running smoothly. The gearbox is the core component of the wind turbine, it can be said to be the heart of the gear-driven fan, and it is crucial to the normal operation of the entire system. According to statistics, among the main causes of wind farm outages, gear box damage accounts for 35%. Therefore, the design and manufacture of gearboxes are usually very advanced and expensive...
