HYDRAULIC UNIT FOR ADJUSTING THE ROTOR BLADES OF A WIND TURBINE

A windmill with a gondola in which a rotor is fixed is disclosed. The angle of attack of the rotor blades mounted on the rotor hub can be adjusted by a hydraulic adjuster mechanism, depending on the wind strength. According to the invention, essential components of said adjuster mechanism, such as h...

Summary:A windmill with a gondola in which a rotor is fixed is disclosed. The angle of attack of the rotor blades mounted on the rotor hub can be adjusted by a hydraulic adjuster mechanism, depending on the wind strength. According to the invention, essential components of said adjuster mechanism, such as hydraulic pumps (22) and the drive for the same and optionally pressure reservoirs etc, are fixed on the rotor or the rotor shaft. A windmill with a gondola in which a rotor is fixed is disclosed.

Offenbart ist ein Windrad mit einer Gondel, in der ein Rotor gelagert ist. Der Anstellwinkel der von der rotornabe gelagerten Rotorblätter kann mittels eines hydraulischen Stellmechanismus in abhängigkeit von der Windstärke eingestellt werden. Erfindungsgemäss sind wesentliche Bauelemente des Stellmechanismus, wie Hydropumpe (22) und deren Antrieb sowie ggfs. Druckmittelspeicher etc. am Rotor bzw. der Rotorwelle gelagert. L'invention concerne une roue éolienne comprenant une nacelle dans laquelle un rotor est monté. L'angle d'incidence des pales du rotor montées sur le moyeu du rotor peut être réglé à l'aide d'un mécanisme de réglage hydraulique en fonction de la force du vent. Selon la présente invention, des composants essentiels de ce mécanisme de réglage, tels que la pompe hydraulique (22), son entraînement et éventuellement l'accumulateur de pression, sont montés sur le rotor ou l'arbre du rotor.
