| description | La présente invention concerne une boîte de transmission de puissance comportant un roulement (10) à billes à contact oblique comportant une première rangée (11) de billes munie d'une pluralité de billes (13), une seconde rangée (12) de billes munie d'une autre pluralité de billes (14), au moins une bague intérieure (15, 15', 15") et au moins une bague extérieure (16).Selon l'invention, dans un mode de fonctionnement dégradé dudit roulement (10), la première rangée (11) de billes est configurée pour transmettre d'une part au moins un premier effort axial (F1) orienté selon un premier axe (AX1) et d'autre part au moins un second effort axial (F2) orienté selon un second axe (AX2) opposé au premier axe (AX1), la seconde rangée (12) de billes transmettant aucun effort axial.
A gearbox including an angular contact ball bearing comprising a first row of balls provided with a plurality of balls, a second row of balls provided with another plurality of balls, at least one inner ring and at least one outer ring. According to the invention, in a degraded operating mode of the bearing, the first row of balls is configured to transmit at least one first axial force oriented along a first axis and at least one second axial force oriented along a second axis opposite the first axis, the second row of balls transmitting no axial force. |
