Rotor hub of a wind energy plant
View Patent ↗A rotor hub ( 10 ) of a wind power plant for a rotor, in particular with at least one rotor blade is provided, wherein a hub core body ( 12 ) and at least one hub outer body ( 16 ) are connected together by means of a flange connection ( 18 ). The rotor hub ( 10 ) is further characterized in that the flange connection ( 18 ) is constructed with a predetermined tilt angle (α) towards the rotational axis ( 24 ) of the rotor, wherein the tilt angle (α) of the flange connection ( 18 ) is constructed larger than the tilt angle (α) of the rotor blade connection surface of the hub outer body ( 16 ). Furthermore, a wind power plant may be provided with the rotor hub ( 10 ).
