Abstract

L'invention concerne un roulement (10), comportant une bague intérieure (12) et une bague extérieure (14) entourant la bague intérieure (12), chacune des deux bagues (12, 14) comportant deux faces d’extrémité (121, 141) opposées présentant une portée annulaire de guidage (122, 142) ; des corps roulants (18) logés dans un volume annulaire (16) entre les deux bagues de roulement (12, 14) pour permettre une rotation relative entre les deux bagues de roulement (12, 14); deux flasques (26) annulaires opposés, recouvrant chacun une des portées annulaires de guidage (122) de la bague intérieure (12) et respectivement (142) de la bague extérieure (14) pour fermer axialement le volume annulaire (16) et guider l’une par rapport à l’autre les deux bagues de roulement (12,14). Suivant l’invention, les deux flasques (26) sont fixés l’un avec l’autre par des moyens d’assemblage (30) traversant axialement le volume annulaire (16) et sont espacés entre eux circonférentiellement d’au moins un secteur angulaire ( ) prédéterminé de manière à séparer les corps roulants (18) en plusieurs groupements (180) de plusieurs corps roulants (18) adjacents deux à deux en contact. (Fig. 8B)The invention relates to a bearing (10), comprising an inner ring (12) and an outer ring (14) surrounding the inner ring (12), each of the two rings (12, 14) comprising two end faces (121, 141) opposed having an annular guide surface (122, 142); rolling bodies (18) housed in an annular volume (16) between the two rolling rings (12, 14) to allow relative rotation between the two rolling rings (12, 14); two opposite annular flanges (26), each covering one of the annular guide surfaces (122) of the inner ring (12) and respectively (142) of the outer ring (14) to axially close the annular volume (16) and guide the 'one relative to the other the two bearing rings (12,14). According to the invention, the two flanges (26) are fixed together by assembly means (30) passing axially through the annular volume (16) and are spaced from each other circumferentially by at least one angular sector. ( ) predetermined so as to separate the rolling bodies (18) into several groups (180) of several adjacent rolling bodies (18) two by two in contact. (Fig. 8B)
