Abstract

La présente invention concerne un roulement à rouleaux doté de deux rangées qui peut s'utiliser avec un couple faible en supprimant la résistance croissante à l'agitation de lubrifiant tout en prévenant efficacement le désalignement des rouleaux et en réduisant la génération de chaleur lors de son utilisation. Le roulement à rouleaux doté de deux rangées comprend : un anneau externe (1) doté de deux gorges de roulement externes (10) formées sur la surface circonférentielle interne ; un anneau interne (2) doté de deux gorges de roulement internes (20) formées sur la surface circonférentielle externe à l'opposé des gorges de roulement externes (10) de l'anneau externe (1) ; et un grand nombre de rouleaux (3) disposés dans le chemin de roulement où les gorges de roulement externes (10) et internes (20) sont formées les unes en face des autres. Les gorges de roulement externes (10) et internes (20) présentent une section transversale sensiblement en forme de V obtenue en permettant à une face de roulement (17) sur laquelle roule le rouleau (3) de croiser la surface de régulation (14) du désalignement, qui est opposée à la surface de l'extrémité axiale du rouleau (3), au niveau d'un espace minuscule. De plus, une paire de gorges annulaires (15a, 15b) est formée sur la surface de régulation (14) du désalignement de la gorge de roulement externe (10) le long de la circonférence de l'anneau externe (1) tout en maintenant interposée une partie du rouleau (3) opposée à l'axe de rotation de celui-ci.
