The role of rotary body in 500 w small wind turbine and its structural characteristics

Apr 09, 2019

The rotary body is one of the important components of the 500 w small wind turbine. Its function is to support the installation of the generator, the wind wheel and the tail speed governing mechanism, etc., and to ensure that the above-mentioned working parts change with the wind speed and wind direction according to their respective working characteristics. The upper end of the frame is free to rotate.

 

The structure and installation method of the 500 w small wind turbine rotor are different. Among them, the eccentric and tail-type revolving body is currently widely used in China. In order to improve the working performance of the wind wheel, an angle of 5 to 10 degrees is designed between the plane on the rotating body and the horizontal plane. The generator is installed on the upper plane of the rotating body, so that the generator shaft has an elevation angle of 5 to 10 degrees, thereby improving the stability and reliability of the working of the wind wheel.

 

The eccentricity between the wind turbine shaft and the center of rotation is an important structural parameter for the accurate speed regulation of the 500 w small wind turbine speed control mechanism. When the wind speed reaches the speed limit wind speed, the eccentricity can accurately generate a moment that forces the wind wheel to twist, so that the wind wheel immediately starts the side shift adjustment. If the wind speed continues to increase, the torsional moment of the wind wheel also increases, and the wind wheel continues to deflect until it reaches the limit position of the speed limit parking.

 

The empennage and the tail connecting lug on the slewing body are coupled by a pin, and the pin has a designed space reclining angle and side yaw angle when installed, due to the presence of the space reclining angle and the side yaw angle, when the wind When the wheel is biased, the tail is gradually lifted, and the raised tail is attempted to return to its original position under the action of gravity. Once the wind speed is reduced, the recovery torque under the gravity of the tail forces the tail to return to the original position, so that the wind wheel windward.www.titanwindturbine.com
