Abstract

A hub (100) for a wind turbine (200), comprising: a hub body (110) having a first blade bearing flange (120), a second blade bearing flange (120) and a main bearing flange (130), and a stiffening structure (140) stiffening a first portion (112) of the hub body (110), wherein the first portion (112) is arranged adjacent to the main bearing flange (130) and between the first blade bearing flange (120) and the second blade bearing flange (120). This hub has the advantage that a stiffness (or a rigidity) of the hub body can be increased close to the main bearing flange. For example, a stress on a specific position in a main bearing mounted to the main bearing flange can vary due to static and/or dynamic loads. By increasing the stiffness of the hub body, the load is distributed more evenly and the variation of the stress can be reduced significantly. Thus, a service life of a main bearing mounted to the main bearing flange can be increased significantly, leading to longer operation times, reduced servicing costs and increased efficiency of the wind turbine.
