Title
(EN) A BEARING UNIT FOR A YAWING SYSTEM OF A WIND TURBINE
(FR) UNITÉ DE PALIER POUR UN SYSTÈME D'ORIENTATION POUR UNE ÉOLIENNE
Abstract
(EN)
This invention concerns a bearing unit (5) for a bearing assembly (23) of a yawing system (27) of a wind turbine (10). The wind turbine (10) comprises a tower (12) and a nacelle (14) connected by the yawing system (27). The yawing system (27) comprises a gear ring (24) comprising gear-toothed arrangement (33) configured to interact with a gear wheel of a motor to allow orientation of the nacelle (14) with respect to the tower (12). The bearing unit (5) comprises: an adjuster element (11) arranged to be moveably secured to the bearing assembly (23); a body element (8) translatable relative to the adjuster element (11); a bearing element (7) in contact with the body element (8), the bearing element (8) comprising a bearing surface (71) for contacting a surface (26, 28) of the gear ring (24) during use; and, a biasing means (9) positioned between the body element (8) and the adjuster element (11) for applying a tension force to the bearing unit (5) to bias the bearing element (8) into contact with the surface (26, 28) of the gear ring (24) during use. The adjuster element (11) is configured to adjust the tension force applied to the bearing unit (5) by controlling the translation of the body element (8), and the bearing unit (5) is configured such that respective surfaces (25, 21) of the adjuster element (11) and the body element 8 are visible during use.

La présente invention concerne une unité de palier (5) pour un ensemble de palier (23) d'un système d'orientation (27) pour une éolienne (10). L'éolienne (10) comprend une tour (12) et une nacelle (14) reliée par le système d'orientation (27). Le système d'orientation (27) comprend une couronne dentée (24) comprenant un arrangement denté (33) configuré pour interagir avec une roue dentée d'un moteur pour permettre l'orientation de la nacelle (14) par rapport à la tour (12). L'unité de palier (5) comprend : un élément de réglage (11) agencé pour être fixé de façon mobile à l'ensemble palier (23); un élément de corps (8) pouvant se déplacer par rapport à l'élément de réglage (11); un élément de palier (7) en contact avec l'élément de corps (8), l'élément de palier (8) comprenant une surface d'appui (71) pour entrer en contact avec une surface (26, 28) de la couronne dentée (24) pendant l'utilisation; et un moyen de sollicitation (9) positionné entre l'élément de corps (8) et l'élément de réglage (11) pour appliquer une force de tension à l'unité de palier (5) afin de solliciter l'élément de support (8) en contact avec la surface (26, 28) de la couronne dentée pendant l'utilisation. L'élément de réglage (11) est configuré pour ajuster la force de tension appliquée à l'unité de support (5) par contrôle de la translation de l'élément de corps (8), et l'unité de palier (5) est configurée de telle sorte que les surfaces respectives (25, 21) de l'élément de réglage (11) et de l'élément de corps (8) sont visibles pendant l'utilisation.
