Problems solved by technology

CN102041148A uses ester fully synthetic base oil. The invention improves the service life of wind power gear oil and solves the problems of poor compatibility and non-biodegradable sealing materials of existing synthetic hydrocarbon gear oil. However, the hydrolysis of ester oil is stable Poor resistance, easy to decompose when meeting water, and the additives used in this invention are imported compounding agents

Abstract

The invention discloses a wind-turbine gear oil composition. The wind-turbine gear oil composition is characterized by comprising the following components: (1), full-synthetic base oil, (2), at least one phenol-type antioxidant or amine-type antioxidant, (3), at least one sulphur-containing or phosphor-containing anti-wear reagent at extreme pressure, (4), at least one antirust agent, (5), at least one metal passivator and (6), at least one demulsifying agent. The needed full-synthetic base oil is added to a blending kettle with a stirrer in proportion according to the viscosity grade of the wind-turbine gear oil composition; and other components are added to the blending kettle in proportion for being blended to obtain the wind-turbine gear oil composition disclosed by the invention after the full-synthetic base oil is blended. According to the wind-turbine gear oil composition disclosed by the invention, the full-synthetic base oil is adopted, so that the wind-turbine gear oil composition has long service life even under the harsh working conditions and is suitable for the lubricating requirements of a gearbox which is used within the wide range; and meanwhile, the pole tension anti-wear additive with micropitting performance is added, so that the formation of point erosion is effectively avoided or restrained, and the normal operation of a large heavy-load mechanical gear transmission device is ensured.

Description

technical field [0001] The invention relates to the technical field of industrial gear lubricating oil, in particular to a wind power gear oil composition used in a wind power gear box. Background technique [0002] In today's increasingly tense and scarce energy sources, people are gradually beginning to realize the importance of environmental protection and renewable energy. 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 ou...
