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.

A wind turbine flange connection between a hub of a wind turbine and a nacelle of the wind turbine,
- wherein the hub comprises a first flange,
- wherein the nacelle comprises a second flange,
- wherein 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, and
- wherein the first flange comprises a plurality of holes and the second flange comprises a plurality of holes corresponding to the plurality of holes in the first flange,
- wherein the plurality of holes of the first and second flange are arranged in the first and second flange based upon the axial, rotational and tilting forces between the hub and nacelle;
- and
- a plurality of shear pins arranged in the plurality of holes.
A hub of a wind turbine comprising a flange that is prepared and arranged in a way to be connected to a nacelle of a wind turbine,
- wherein the flange comprises a plurality of first holes that are prepared and arranged in a way to interact with a connection means being used to connect the hub to the nacelle,
- wherein the flange comprises a plurality of second holes that are prepared and arranged in a way to contain a plurality of shear pins to be used to transfer rotational, axial and tilting forces from the hub to the nacelle when the hub is connected to the nacelle.
