When the gearbox is subjected to the force from the wind wheel and the reaction force produced by the gear transmission, it must have enough rigidity to withstand the load and torque to prevent deformation and ensure the transmission quality. The design of gearbox should be carried out according to the layout arrangement, processing and assembling conditions, convenient inspection and maintenance of wind turbine power transmission. With the rapid development of the gearbox industry, more and more industries and different enterprises have applied to the gearbox, there are more and more enterprises in the gearbox industry to grow and develop.
According to modular design principle of unit structure, gearbox greatly reduces the type of parts and is suitable for large-scale production and flexible selection. Reducer Spiral bevel gears, helical gears are used in high quality alloy steel carburizing quenching, tooth surface hardness up to 60±2HRC, tooth surface grinding precision up to 5-6.
