Abstract

Le segment de cage pour roulement délimitant une pluralité de poches (18) traversantes pour la réception de rouleaux (10) et comprenant des première et deuxième parois (49) s’étendant dans le sens circonférentiel et pourvues de surfaces intérieures en regard l’une de l’autre et formant des surfaces de butée pour les faces d’extrémités des rouleaux (10), et une pluralité de poutres (52a, 52b, 52c, 52d, 52e, 52f) s’étendant transversalement entre les première et deuxième parois (49, 51) et reliant lesdites parois, chaque poche (18) étant délimitée dans le sens circonférentiel par deux poutres (52a, 52b, 52c, 52d, 52e, 52f) successives et chaque poutre délimitant en partie deux poches (18) successives. Chaque poutre (52a, 52b, 52c, 52d, 52e, 52f) comprend, à une extrémité latérale (54a, 54b, 54c), une protubérance (56a, 56b, 56c) de forme extérieure concave et destinée à venir en contact avec la surface extérieure d’au moins un rouleau (10), deux protubérances étant en regard dans le sens circonférentiel pour chaque poche traversante (18).
