Abstract

Une bague de support de roulement comprend une pluralité de plaques de contact dépassant radialement des surfaces circonférentielles interne et externe de la bague. Les parties flexibles de la bague sont définies entre les plaques de contact et ont une épaisseur radiale inférieure à celle de la bague au niveau des plaques de contact, de façon à permettre une déformation élastique de la bague dans une direction radiale entre les plaques de contact. Les ouvertures sont dimensionnées pour permettre un écoulement sans restriction de l'huile, notamment dans les parties flexibles de la bague.
