Abstract

L’invention propose un palier (100) de roulement comprenant : - une bague interne (12) et une bague externe coaxiales selon un axe de rotation (X) et entre lesquelles sont disposés des éléments roulants (16), - une cage annulaire (102) de roulement centrée autour de l’axe de rotation et agencée entre la bague interne et la bague externe, la cage annulaire présentant une face annulaire externe en regard de la bague externe et une face annulaire interne en regard de la bague interne,dans lequel la cage annulaire comprend une pluralité de logements (108) débouchant au niveau de la face interne et au niveau de la face externe et agencés entre un premier bord annulaire latéral (1061) de la cage annulaire et un second bord annulaire latéral (1062), lesdits logements logeant les éléments roulants, et dans lequel au moins l’une de la face externe et de la face interne comprend une pluralité de premières rainures (1041) s’étendant depuis lesdits logements jusqu’au premier bord annulaire latéral et une pluralité de secondes rainures (1042) s’étendant depuis lesdits logements jusqu’au second bord annulaire latéral, de sorte que les rainures sont aptes à faire circuler un fluide de lubrification dans le palier de roulement. Figure à publier avec l’abrégé : figure 1The invention proposes a rolling bearing (100) comprising: - an inner ring (12) and an outer ring coaxial along an axis of rotation (X) and between which are arranged rolling elements (16), - an annular cage ( 102) bearing centered around the axis of rotation and arranged between the inner ring and the outer ring, the annular cage having an outer annular face facing the outer ring and an inner annular face facing the inner ring, in wherein the annular cage comprises a plurality of housings (108) emerging at the level of the internal face and at the level of the external face and arranged between a first lateral annular edge (1061) of the annular cage and a second lateral annular edge (1062) , said housings housing the rolling elements, and in which at least one of the external face and the internal face comprises a plurality of first grooves (1041) extending from the said housings to the first annular lateral edge and a plurality of second grooves (1042) extending from said housings to the second lateral annular edge, such that the grooves are adapted to circulate a lubricating fluid in the rolling bearing.
