Problems solved by technology

[0002] At present, there are only a few countries in the world that can design and manufacture large-scale wind turbines. In the late 1990s, my country, through the introduction of technology and continuous localization, has the ability to produce large-scale wind turbines. The equipment is expensive, the working environment is harsh, it is inconvenient to disassemble and repair the main parts on site, and the design requires long service life and other working characteristics

Embodiment Construction

[0007] 1. Lubrication of the wheel box:

[0008] The gearbox is the main lubricating part of the wind turbine. The oil consumption accounts for about 3 / 4 of the oil consumption of the wind turbine. For very high generator speed (usually 1500r / min), oil pool splash lubrication or pressure forced circulation lubrication is often used.

[0009] 2. Lubrication of generator bearings:

[0010] The bearing is the main lubrication point of the generator, and the long-term operating temperature can reach above 80°C. In summer, it is exposed to direct sunlight in the wilderness, and the temperature will be higher. Therefore, it is required that the bearing grease of the generator can maintain good lubrication at high temperature without loss , and the power of the generator is large, the grease is required to have good anti-wear extreme pressure performance, anti-oxidation performance and anti-rust performance, and regular manual filling of grease is often used to ensure the normal ope...

Abstract

The invention provides a lubricating method for wind power generator, which comprises a lubricant, a wind power generator. Compound lubricant is adopted; the main lubricating parts of the wind power generator include a gear box, a generator bearing, a crab system bearing and gear, a hydraulic brake system and a min bearing. Compared with the ordinary mineral grease, the adopted compound lubricant has the advantages of excellent viscosity-temperature characteristics and little impact due to temperature change, is able to ensure easy startup under low temperature and no loss under high temperature, thereby providing sufficient lubrication for the friction parts. In addition, with excellent stability of thermal oxidation and little loss in vaporization, the lubricant can be used for a long time under rigid working condition and climatic situation. Especially, with high biodegradation rate, the compound lubricant can be widely promoted as it results in no pollution to the soil and water source.

Description

technical field [0001] The invention relates to a lubricating method for a generator, in particular to a lubricating method for a wind power generator. Background technique [0002] At present, there are only a few countries in the world that can design and manufacture large-scale wind turbines. In the late 1990s, my country, through the introduction of technology and continuous localization, has the ability to produce large-scale wind turbines. The equipment is expensive, the working environment is harsh, it is inconvenient to disassemble and repair the main parts on site, and the design requires long service life and other working characteristics. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a practical lubricating method for wind power generators. [0004] In order to achieve the above object, the present invention takes the following measures to achieve: [0005] A lubricating method for a wind-driven genera...
