Abstract:
1. A connection between components of a wind turbine having a diameter of more than 0.5 m comprising: a first component having a contact surface; a second component having a first contact surface and a second contact surface; a third component having a contact surface, wherein a surface of the contact surface of the first component is softer than a surface of the first contact surface of the second component, wherein the contact surface of the first component and the first contact surface of the second component face each other and the first and second component are braced together in a connected state while the third component contact surface has a surface facing toward said second contact surface of the second component, wherein the second component is an intermediate connection part between the first component and the third component and the surfaces of the first and second contact surfaces of the second component are annealed; and, surfaces of the first and second contact surfaces of the second component each have a higher hardness than the surfaces of the contact surfaces of the first and the third component lying opposite the contact surfaces of the second component.
