Wind driven generator yawing device with locking function

Abstract

The invention relates to a wind driven generator yawing device with a locking function. The wind driven generator yawing device is characterized by comprising a tower drum mechanism, a yaw driving mechanism, a transmission inner gear ring, a gear ring cooperation supporting wheel carrier, a gear ring cooperation adjusting wheel carrier, a locking mechanism, a locking chuck and an engine room support frame, wherein the engine room support frame comprises engine room support frame cross beams, an engine room support frame connecting plate, engine room support frame vertical beams and a locking mechanism connecting plate; the middle parts of the two engine room support frame cross beams are connected with the two engine room support frame vertical beams; the engine room support frame connecting plate is connected between the lower ends of the two engine room support frame vertical beams; the locking mechanism connecting plate is arranged on the side surface of one engine room support frame vertical beam; the upper end of the tower drum mechanism is fixedly connected with the transmission inner gear ring and the locking chuck; the locking chuck is arranged below the transmission inner gear ring; the yaw driving mechanism is fixedly connected on the engine room support frame connecting plate; and the locking mechanism is fixed to the locking mechanism connecting plate.

Description

technical field [0001] The invention relates to the technical field of wind power generator transmission, in particular to a wind power generator yaw device with a locking function. Background technique [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 directio...

[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
