Abstract
A wind turbine is described. The turbine includes a hub with one or more blades that rotatably mounted on a frame and operatively coupled to a shaft. The shaft is provided at least partially internally to the frame, and a center piece from which a plurality of spokes extends substantially radially is mounted on the shaft. The hub is provided with a plurality of circumferentially arranged axial protrusions. Flexible elements are arranged to connect the spokes to the protrusions.

A wind turbine comprising:
- a frame;
- a hub with one or more blades, the hub being rotatably mounted on the frame and having a plurality of circumferentially arranged axial protrusions;
- a shaft operatively coupled to the hub and being disposed at least partially internally to the frame;
- a center piece mounted on the shaft and having a plurality of spokes extending substantially radially;
- and
- flexible elements arranged to connect the spokes to the protrusions.
A method of assembling a wind turbine that includes a frame, a hub with one or more blades and, plurality of circumferentially arranged axial protrusions, a rotor shaft, a center piece having a plurality of spokes extending substantially radially, and flexible elements arranged to connect the spokes to the protrusions, the method comprising:
- mounting the hub on the frame;
- disposing the rotor shaft at least partially internally in the frame;
- mounting the center piece on the rotor shaft;
- positioning a first flexible element between a first protrusion and a first spoke;
- applying pressure to compress the first flexible element;
- and
- positioning a second flexible element between the first protrusion and a second spoke or between a second protrusion and the first spoke.
