Patent ID: 6911741

Claim:
Wind power plant with a wind turbine with a turbine shaft ( 8 ) which with a generator shaft ( 22 ), which can be an extension of the turbine shaft, is connected to the rotor ( 12 ) of all electric generator ( 11 ), wherein the rotor ( 12 ) is radially surrounded by a stator ( 19 ), wherein the turbine shaft ( 8 ) is journalled in two bearing housings ( 6 , 7 ) with bearings ( 9 , 10 ) arranged on a base ( 4 ) at the top of a tower ( 1 ), wherein the base ( 4 ) is pivotable around a vertical axis, and wherein a motor ( 3 ) is provided to effect the pivoting, characterized in that the generator shaft ( 22 ) is integrated with or rigidly connected to a flexing turbine shaft ( 8 ), that the stator ( 19 ) and rotor ( 12 ) are carried by the generator shaft ( 22 ), to allow the generator ( 11 ) to follow the flexing movement of the turbine shaft ( 8 ), and that the stator ( 19 ) is locked against turning by a non-rotatable coupling ( 20 ) which transfers substantially no bending moment or axial force acting against the flexing of the turbine shaft ( 8 ) due to the bending moment acting on the turbine shaft ( 8 ) from its hub, the bearings ( 9 and 10 ) being provided to allow flexing of the turbine shaft ( 8 ).
