Abstract

The invention provides special castor-oil-based gear oil for wind power generation. The special castor-oil-based gear oil for wind power generation is formed through combination of castor-oil-based base oil and other additives. The special castor-oil-based gear oil comprises the following components in percentage by mass: 0-30% of other types of base oil, 0.1-2% of friction modifier, 0.1-3% of extreme pressure anti-wear agent, 0.01-0.3% of metal passivator, 0.1-2% of antioxidant agent, 0.001-0.5% of demulsification agent, 0.01-0.5% of anti-rust agent, 0.001-0.3% of anti-foaming agent and the balance of castor-oil-based base oil. The special castor-oil-based gear oil provided by the invention has the advantages of having excellent biological degradability, being capable of being decomposed under the effect of microorganisms even if leaking into environments, having no pollution to environments, and having excellent extreme pressure anti-wear performance, good thermal oxidation stability, low-temperature performance, viscosity-temperature performance, anti-emulsification property and long service life.

Description

technical field [0001] The invention belongs to the field of lubricants and relates to a castor-based special gear oil for wind power generation. Background technique [0002] As an important resource for the development of green new energy today, wind energy has been valued by various countries. Governments of various countries have formulated preferential policies to encourage enterprises and individuals to actively participate in wind power generation, and increase the development of wind power. Due to the advantages of short construction period, flexible installed capacity, no fuel consumption, and no environmental pollution, wind power has become an important new force in the field of new energy. [0003] The gearbox is the most important part of wind power equipment, and it is also the product with the highest requirements for the amount and performance of lubricating oil. According to the experience of the European wind power industry, the damage to the gearbox acco...
