The device (1) comprises at least one pressing member (2) and means (3) for attaching it to a wind turbine part (B), for example a blade root (7), which may have a relative movement with regard to a first part (A), for example a bearing (6) in a pitch blade mechanism, said first part (A) having a seat (5) into which the joint (4) is to be fitted. Upon relative rotation between said first parts (A, B), the pressing member (2) presses the seal (4) into the seat (5). A method for fitting the seal (4) into the seat (5) is also provided. Operations of maintenance or partial or complete replacement of the seal (4) can be carried out in situ on the wind turbine and also on pitch bearing manufacturing easily and effectively.

La présente invention concerne un dispositif (1) comprenant au moins un élément de pression (2) et un moyen (3) pour fixer celui-ci à une partie turbine éolienne (B), par exemple une emplanture (7), qui peut avoir un mouvement relatif par rapport à une première partie (A), par exemple un palier (6) dans un mécanisme de pas de pales, ladite première partie (A) ayant un siège (5) dans lequel le joint (4) doit être installé. Lors d'une rotation relative entre lesdites premières parties (A, B), l'élément de pression (2) pousse le dispositif d'étanchéité (4) dans le siège (5). La présente invention concerne également un procédé destiné à installer le dispositif d'étanchéité (4) dans le siège (5). Les opérations de maintenance ou de remplacement partiel ou complet du dispositif d'étanchéité (4) peuvent être effectuées facilement et efficacement in situ dans la turbine éolienne et également lors de la fabrication de l'articulation de pas.
