Zusammenfassung:A hub (1) for a wind turbine is disclosed, the hub (1) comprising a continuous shell forming an internal space within a hollow body, and the hub (1) further comprising a main shaft flange (2) adapted to connect the hub (1) to a main shaft and one or more blade flanges (3), each blade flange (3) being adapted to connect the hub (1) to a wind turbine blade. The hub (1) comprises one or more reinforcement elements connected to the shell and extending from an inner surface of the shell and inwardly into the internal space within the hollow body. This allows the regions between the blade flanges (3) 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.
