Abstract
Un segment de support (20) d'un roulement à rouleaux coniques comprend : une pluralité de parties en colonne (23) s'étendant dans la direction axiale ; et une paire de parties en arc (21, 22) s'étendant dans la direction circonférentielle et reliant les parties en colonne (23) respectives. La pluralité de parties en colonne (23) et la paire de parties en arc (21, 22) forment des poches (16) qui maintiennent des rouleaux coniques entre des parties en colonne (23, 23) adjacentes. Dans les parties en arc (21, 22) ou les parties en colonne (23), des surfaces (sf) formant les poches (16) sont inclinées par rapport à la direction radiale dans les poches (16) du segment de support (20). La totalité ou une partie des parties de coin (Cr) dans chacune des poches (16) ont une forme ronde qui devient progressivement plus grande vers un côté ou l'autre côté dans la direction radiale.
