[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. Wind is a pollution-free energy source. Using wind power for power generation is very environmentally friendly and can generate huge amounts of electricity. Therefore, more and more countries are paying more attention to wind power generation.

[0003] During wind power generation, the power of the blades needs to be transmitted to the generator through a transmission machine, and then the generator is driven to generate electricity.
