A wind turbine including a main shaft rotatable around a rotation axis, the main shaft comprising:
- a first piece axially extending along the rotation axis,
- at least a second piece axially extending along the rotation axis, the second piece being axially adjacent to the first piece,
- a plurality of connections for fixing the second piece to the first piece.
A main shaft for a wind turbine axially extending along a rotation axis, the main shaft comprising:
- a first piece axially extending along the rotation axis,
- at least a second piece axially extending along the rotation axis, the second piece being axially adjacent to the first piece,
- a plurality of connections for fixing the second piece to the first piece.
A method for manufacturing a main shaft for a wind turbine axially extending along a rotation axis, the method comprising:
- manufacturing an first axially extended piece of the main shaft,
- manufacturing at least a second axially extended piece of the main shaft,
- fixing the second piece to the first piece though a plurality of connections in such a way that the second piece is axially adjacent to the first piece along the rotation axis.
The method for manufacturing a main shaft for a wind turbine axially extending along a rotation axis, the method comprising:
- manufacturing at least a third axially extended piece of the main shaft,
- fixing the third piece to the second piece though a plurality of connections in such a way that the third piece is axially adjacent to the second piece.
