More Information
Summary:The present invention describes a wind turbine comprising a hub, at least one blade and at least one pitch bearing to connect the at least one blade to the hub, the at least one pitch bearing comprising at least an inner ring and an outer ring, and at least a rolling race, wherein the wind turbine further comprises at least a tensioning system configured to exert a radial compression force to at least a part of the outer ring of the at least one pitch bearing, thus increasing the resultant stiffness of the at least one pitch bearing. La présente invention concerne une éolienne comprenant un moyeu, au moins une pale et au moins un palier de pas pour relier l'une ou les pales au moyeu, l'un ou les paliers de pas comprenant au moins une bague intérieure et une bague extérieure, et au moins une bague de roulement. L'éolienne comprend en outre au moins un système de tension configuré pour exercer une force de compression radiale sur au moins une partie de la bague extérieure du ou des paliers de pas, augmentant ainsi la rigidité résultante du ou des paliers de pas.
