Abstract
Official abstract text for this publication.
Provided is a wind turbine including a hub and several blades rotatably attached to the hub by means of blade bearings including an inner ring coupled with the respective blade and an outer ring coupled with the hub, or vice versa, and rolling elements provided between the rings, wherein the outer ring or the inner ring has a cross section with a circumferentially varying thickness.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wind turbine comprising: a hub; a plurality of blades rotatably attached to the hub by means of blade bearings comprising an inner ring coupled with a respective blade and an outer ring coupled with the hub, or vice versa, and rolling elements provided between the inner ring and the outer ring, wherein the outer ring or the inner ring has a cross section with a circumferentially varying thickness; wherein the outer ring or the inner ring is arranged such that a section with a largest thickness is positioned towards a front side of the hub and a section with a smallest thickness is positioned towards a rear side of the hub. 2. The wind turbine according to claim 1 , wherein the circumferentially varying thickness varies continuously between a maximum thickness and a minimum thickness. 3. The wind turbine according to claim 1 , wherein the hub comprises an attachment area with a surface having a geometry corresponding to an attachment side surface of the outer ring or the inner ring. 4. A bearing for a wind turbine for attaching a blade to a hub, comprising: an inner ring to be attached to the blade; and an outer ring to be attached to the hub, or vice versa, with rolling elements being provided between the inner ring and the outer ring; wherein the outer ring or the inner ring has a cross section with a circumferentially varying thickness; wherein the outer ring or the inner ring is arranged such that a section with a largest thickness is positioned towards a front side of the hub and a section with a smallest thickness is positioned towards a rear side of the hub. 5. The bearing according to claim 4 , wherein the circumferentially varying thickness varies continuously between a maximum and a minimum thickness.
