A wind turbine, a method for coupling a first drive train component of the drive train of a wind turbine with a second drive train component of the drive train, and use of a wind turbine
A wind turbine (1) comprising a drive train (13), said drive train (13) including at least one rotor (4) for transforming wind into rotation of a rotor hub (11), to provide a pair of drive a generator (8) to transform at least part of said drive torque into electrical power, and at least one coupling (12) to connect a first component (14) of the drive train with a second component (15) of the drive train drive to transfer said drive torque between said components (14, 15), said coupling (12) comprises a first coupling piece (16) with a first coupling area (18), said first coupling area (18) being connected with a second coupling area (19) of a second coupling part (17), whereby said driving torque is transferred from one of said areas (18, 19) to the other of said areas (18, 19) during the operation of said coupling to (12), said first coupling area (18) is provided with a first positive coupling structure (20) that engages with a corresponding second positive coupling structure of said second coupling area (19), and in which said first and second positive coupling structures (20, 32) extend inwardly from positions near or on an outer periphery (33) of the first and second coupling parts (16, 17), respectively, wherein said first coupling area (18) and said second coupling area (19) comprise fixing means (24) for substantially maintaining at least one axial position of said first coupling area (18) in relation to said second coupling area (19) at least during operation of said coupling (12), and characterized in that said second coupling area (19) of said second component (15) of the drive train comprises a central opening at through which said first component (14) of the drive train can be assembled and dismantled.
