[0002] Gearboxes are widely used, for example, in wind turbines. Gearboxes are an important mechanical component that is widely used in wind turbines. Their main function is to transfer the power generated by the wind rotor under the action of wind to the generator and make it obtain a corresponding speed. Usually, the speed of the wind rotor is very low, far from the speed required for the generator to generate electricity. It must be achieved through the speed-increasing effect of the gear pair of the gearbox, so the gearbox is also called a speed increaser. With the development of society, gearboxes are used when wind power needs to be converted into power.
