Title (EN) WIND TURBINE BLADE BEARING AND SEAL ARRANGEMENT
(FR) ROULEMENT DE PALE DE TURBINE ÉOLIENNE ET AGENCEMENT D'ÉTANCHÉITÉ
Abstract:
(EN) A blade bearing for mounting a blade of a wind turbine to a hub of the wind turbine comprises first and second bearing rings arranged next to each other and a seal arrangement covering a space between the first and second bearing rings. One of the first or second bearing rings is configured to mount to the blade, and the other is configured to mount to the hub. The first and second bearing rings each have an axially-facing surface and a radially-facing surface. The seal arrangement includes a first seal element statically coupled to the axially-facing surface of the first bearing ring, a second seal element statically coupled to the axially-facing surface of the second bearing ring, and a holding member secured to the axially-facing surface of the first bearing ring. The first seal element is statically coupled to the holding member. The second seal element is dynamically coupled to the holding member and/or the first seal element.
(FR) L'invention concerne un roulement de pale destiné au montage d'une pale d'une turbine éolienne sur un moyeu de la turbine éolienne. Le roulement comprend des première et seconde bagues de roulement agencées l'une à côté de l'autre et un agencement d'étanchéité qui couvre un espace entre les première et seconde bagues de roulement. Une des première et seconde bagues de roulement est conçue pour être montée sur la pale et l'autre est conçue pour être montée sur le moyeu. Les première et seconde bagues de roulement ont chacune une surface faisant face dans le sens axial et une surface faisant face dans le sens radial. L'agencement d'étanchéité comprend un premier élément d'étanchéité, couplé statique à la surface faisant face dans le sens axial de la première bague de roulement, un second élément d'étanchéité, couplé statique à la surface faisant face dans le sens axial de la seconde bague de roulement, ainsi qu'un élément de maintien, fixé sur la surface faisant face dans le sens axial de la première bague de roulement. Le premier élément d'étanchéité est couplé statique à l'élément de maintien. Le second élément d'étanchéité est couplé dynamique à l'élément de maintien et/ou au premier élément d'étanchéité.
