Problems solved by technology

[0002] With the continuous development and application of wind energy technology, the cost of wind turbines and the utilization rate of wind energy by wind turbines have become research hotspots. Through analysis, there are still many problems in the yaw device of wind turbines that need to be improved. The yaw device in the generator needs a bearing with a larger diameter to cooperate with the tower. Because the processing technology of the large-diameter bearing is relatively complicated, this greatly increases the cost of the wind turbine. In addition, the existing large wind turbines are equipped with Multiple yaw motors, when the yaw reaches an appropriate angle, the yaw motor performs electric braking to make the sweeping surface of the impeller face the wind direction, which consumes a part of electric energy, which greatly increases the energy consumption rate of the wind turbine itself, so Optimizing the design of the hub will be of great significance to improving economic benefits
