A hub for a rotor of a wind turbine, the hub comprising:
- a hollow body rotatable around a rotation axis, the hollow body comprising a blade flange and defining a blade flange area surrounded by the blade flange, the hollow body further comprising a main shaft flange defining a first end, and a second end opposite the first end;
- and
- a stiffening web extending within the blade flange area and defining a web plane,
- wherein a side profile of the web plane extending from the first end to the second end is oriented at a cone angle to the rotation axis, and wherein a thickness of the stiffening web tapers throughout at least a portion of a length of the stiffening web from the first end to the second end.
A wind turbine, comprising:
- a tower;
- a nacelle mounted on the tower;
- a rotor coupled to the nacelle, the rotor comprising a hub and a rotor blade, the hub comprising:
- a hollow body rotatable around a rotation axis, the hollow body comprising a blade flange and defining a blade flange area surrounded by the blade flange, the hollow body further comprising a main shaft flange defining a first end, and a second end opposite the first end;
- and
- a stiffening web extending within the blade flange area and defining a web plane,
- wherein a side profile of the web plane extending from the first end to the second end is oriented at a cone angle to the rotation axis, and wherein a thickness of the stiffening web tapers throughout at least a portion of a length of the stiffening web from the first end to the second end.
