| description | A hub (1) for a wind turbine and a method for fabricating the hub (1) are disclosed. The hub (1) comprises a continuous shell forming a hollow body with a main shaft flange (4) adapted to connect the hub (1) to a main shaft, and one or more blade flanges (5), each blade flange (5) being adapted to connect the hub (1) to a wind turbine blade. The hub (1) further comprises at least two hub parts (2, 3, 7), each hub part (2, 3, 7) being casted separately from a castable material, and each hub part (2, 3, 7) being subsequently connected to at least one other hub part (2, 3, 7) via one or more connecting portions (6), so that at least one blade flange (5) and/or the main shaft flange (4) comprises a section forming part of or being attached to one of the hub parts (2, 3, 7) and a section forming part of or being attached to another hub part (2, 3, 7), thereby ensuring that the casted parts have a size and a weight which are manageable during the manufacture, in particular during the casting. The hub (1) may comprise one or more reinforcement elements arranged at or near the blade flange(s) (5), e.g. comprising an inner wall (8) arranged at a distance to the continuous shell, thereby forming a cavity (9) between the inner wall (8) and the continuous shell. This allows the regions between the blade flanges (5) to be small or narrow, thereby reducing the size and weight of the hub (1), while maintaining a sufficient strength and stiffness of these regions. |
