Abstract:
A wind turbine flange connection between a hub and a nacelle of the wind turbine, a wind turbine, a wind turbine hub and a wind turbine nacelle is provided. The hub of the wind turbine comprises a first flange and the nacelle of the wind turbine comprises a second flange. The first flange and the second flange are connected to each other by a number of connection means, to transfer forces between the first flange and the second flange. The first flange comprises a plurality of holes and the second flange comprises a plurality of holes corresponding to the holes in the first flange. Shear pins are arranged in the holes in the flanges to transfer rotational forces between the hub and the nacelle.
