Lubricants for wind turbine - Part 3. Gear oils
1 Scope
This part of GB/T 33540 specifies the product variety and identification, requirements and test methods, inspection rules, marking, packaging,
transportation and storage of the wind turbine generator gear oil which uses the synthetic oil as the base oil AND added a variety of functional additives. This part is applicable to the gear oil used in the wind turbine gear transmission system, which is composed of the main gearbox, yaw gearbox, and variable pitch gearbox.
The product covered in this part is particularly suitable for the lubrication of the low temperature wind turbine gearbox.
