The lubriion system of the gearbox is of great significance for the normal operation of the gearbox. Large wind power generation gearboxes must be equipped with a reliable forced lubriion system to lubrie the gear meshing area, bearings, etc. with oil spray. Insufficient lubriion accounts for more than half of the causes of gearbox failure. The temperature of lubriing oil is related to component fatigue and the lifespan of the entire system Generally speaking, the maximum oil temperature of a gearbox during normal operation should not exceed 80 ℃, and the temperature difference between different bearings should not exceed 15 ℃. When the oil temperature exceeds 65 ℃, the cooling system begins to operate; When the oil temperature is below 10 ℃, the lubriing oil should be heated to the predetermined temperature before starting.
