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 c
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).
