Abstract

L'invention concerne une unité de palier (10) pour une éolienne, présentant un roulement à rotule (70) disposé dans un carter de palier (12), dans laquelle des corps cylindriques (82, 84) en forme de tonneau sont disposés dans deux séries de corps cylindriques (78, 80) parallèles entre une bague interne (74) segmentée et une bague externe (76) segmentée et dans laquelle la bague interne (74) est disposée sur un arbre principal (72) de l'éolienne. Selon l'invention, le carter de palier (12) présente sur toute sa longueur axiale une fente longitudinale (18) et la géométrie de la section transversale présente de ce fait une bague non divisée, mais ouverte par rapport à la périphérie; la fente longitudinale (18) s'étend parallèlement à une axe central longitudinal (16) du carter de palier (12); la fente longitudinale (18) est disposée au niveau d'une ligne de faîte (14) du carter de palier (12); et la fente longitudinale (18) peut être fermée à l'aide de moyens appropriés (24, 26). Le mode de réalisation à une seule fente du carter de palier (12), lequel est par ailleurs non divisé, lui permet, outre le fait d'offrir une interchangeabilité aisée du roulement à rotule (70), de parvenir à une aptitude aux sollicitations mécaniques nettement supérieure à celle de carters de paliers classiques présentant un mode de construction à demi-coquille ou à coquilles multiples.
