Structural elements of the internal revolving body of a small wind turbine

Nov 28, 2018

The rotary body is one of the important components of the 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 working parts change in accordance with the respective working characteristics with the wind speed and the wind direction. The upper end is free to rotate, and the structure and installation method of the small wind turbine rotor are different. Among them, the eccentric and tail-type rotary body is currently widely used in China.


In order to improve the working performance of the wind turbine of a small wind turbine, an angle of 5 to 10 degrees is designed between the plane and the horizontal plane of the rotary body. 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 rotary center is an important structural parameter for the accurate speed regulation of the 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 empennage connecting ear on the rotator are coupled by a pin, and the pin has a designed space back rake 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 tilted up, 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.http://www.titanwindturbine.com/
