Abstract

The invention provides a lubricant composition for a transmission system of wind power equipment. The lubricant composition provided by the invention is composed of following components by weight percentage contents: 0.1-10% of friction index improver, 0.1-9% of extreme pressure anti-wear agent, 0.01-2% of pour point depressant, 0.01-3% of oxidation and corrosion inhibitor, 0.005-0.1% of anti-foaming agent, 0.001-1% of demulsifying agent, 0.01-1.0% of antirust agent, 0-20% of viscosity index improver and residual amount of basic oil. The lubricant composition provided by the invention can be used for providing excellent lubrication protection to a gear case, bearings and the like of the wind power equipment under the harsh environment conditions.

Description

technical field [0001] The invention relates to a lubricating oil additive, in particular to a lubricant composition for a transmission system of wind power equipment. Background technique [0002] In China, wind farms are mostly concentrated in the northeast, northwest, and coastal areas where the winter is severe, and the working conditions (field, high altitude) and natural environment (sandstorm, large temperature difference, large salt spray) are very harsh. In addition, the gears and bearings in the main gearbox of the wind turbine share the same lubricating system. Oxidation stability, anti-emulsification performance, anti-foam performance, corrosion resistance, cleaning performance and other aspects of performance put forward more stringent requirements. [0003] Judging from the new situation, due to the early development of wind power in foreign countries, the proportion of new energy is also relatively large. In terms of oil for wind power generation, some large...
