20100320769 | Wind Turbine Comprising a Torsional Vibration Absorber - The invention provides a wind turbine comprising a wind-driven rotor for converting wind energy to a mechanical driving force, a power converter for converting the driving force to exploitable power and a transmission system for rotatably transmitting the driving force to the power converter. The transmission system comprises at least one rotatable driving element and a torsional dampening device having a rotatable inertia element which is drivable by the at least one rotatable driving element. The inertia element is connected in such a way to the at least one rotatable driving element that the inertia element dampens torsional vibrations in the rotatable driving element during operation of the wind turbine. | 12-23-2010 |
