Patent ID: 7936080

Claim:
A wind turbine comprising a drive train, said drive train including at least a rotor for transforming wind into rotation of a rotor hub, to provide a drive torque a generator for transforming at least a part of said drive torque into electrical power, and at least one coupling for connecting a first drive train component to a second drive train component for transferring said drive torque between said components, said coupling comprises a first coupling part with a first coupling area, said first coupling area being connected with a second coupling area of a second coupling part, whereby said drive torque is transferred from one of said areas to the other of said areas during operation of said coupling, wherein said first coupling area is provided with a first positive engaging structure engaging a corresponding second positive engaging structure of said second coupling area, and wherein both said first and second positive engaging structures are extending inwardly from positions near or at an outer periphery of the first and second coupling parts, respectively.
