  • Yawing device and wind power plant comprising a yawing device
    Patent number: 6176675
    Abstract: A damping coupling is provided to reduce the oscillations of the yawing device of a wind power plant. The damping coupling transmits forces from a driving device to a yaw drive, and the damping coupling is arranged and positioned in such a way that the transmitted moment is dependent on the difference in the rotational speeds between the input and the output shafts of the coupling. The damping coupling is preferably a hydrodynamic coupling.
