Title (EN) SEALED BEARING
(FR) PALIER ETANCHE
Abstract:
(EN) Sealed bearing incorporating an inner race (13), an outer race ring (14) and a row of elongated rollers (15) disposed between, whereby races (11, 12) and rollers (15) have curved longitudinal section profiles and which rollers (15) are axially moveable between the races relative thereto for allowing mutual misalignment of the races, and whereby at least one sealing member (18) is formed separately, positioned axially outside said rollers (15) but adapted to follow the rollers (15) in a free-floating manner and arranged to provide its sealing effect by frictional engagement, wherein at least one of the inner and outer race rings (13, 14) at the axial outer ends of its race (11, 12) is each provided with a radially projecting motion preventing means (20) of short axial width, arranged to prevent said sealing member (18) from being pressed out from the space between the bearing race rings even at misalignments of the race rings (13, 14) relative to each other.
(FR) L'invention porte sur un palier étanche renfermant un anneau de chemin de roulement interne (13), un anneau de chemin de roulement externe (14) et une rangée de rouleaux de forme allongée (15). Les chemins de roulement (11, 12) ainsi que les rouleaux (15) présentent des profils courbes en section longitudinale et ces derniers sont en mesure de se déplacer axialement entre lesdits chemins afin d'autoriser un décentrage mutuel des chemins de roulement. Le palier comporte un élément d'étanchéité (18) au moins, distinct, et positionné axialement à l'extérieur des rouleaux (15) mais conçu pour les suivre en flottant librement et pour assurer une étanchéité par un engagement à friction. Chaque anneau de chemin de roulement interne et/ou chaque anneau de chemin de roulement externe (13, 14) est pourvu, sur les extrémités externes de son chemin de roulement respectif (11, 12), d'un mécanisme d'immobilisation (20), faisant saillie radialement; ce mécanisme, de largeur axiale réduite, est conçu pour éviter l'expulsion de l'élément d'étanchéité (18) de l'espace situé entre les anneaux de chemin de roulement du palier même en cas de décentrage mutuel des anneaux de chemin de roulement (13, 14).
