Gearbox is an important mechanical component widely used in wind turbine. Its main function is to transfer the power generated by the wind turbine to the generator under the action of wind force and get the corresponding speed.
Usually, the speed of wind wheel is very low, far less than the speed required by generator power generation. It must be achieved through the speed-up effect of gearbox gears. Therefore, the gearbox is also called the speed-up box.
