Title (EN) INTEGRATED TWO-LEVEL BEARING
(FR) ROULEMENT À DEUX NIVEAUX INTÉGRÉ
Abstract:
(EN) A bearing arrangement includes a bearing outer element that defines a first plurality of races opening radially inwardly, a bearing inner element that defines a second plurality of races opening radially outwardly, and a bearing middle element defining a third plurality of races at its radially outer surface thereof and a fourth plurality of races at its radially inner surface thereof. Rolling elements are receivable in the races. The bearing middle element includes an axial protrusion at least at one end thereof that can be received in a housing with respect to which the bearing outer and inner elements are rotatable.
(FR) Un agencement de roulement comprend un élément externe de roulement qui définit une première pluralité de chemins s'ouvrant radialement vers l'intérieur, un élément interne de roulement qui définit une seconde pluralité de chemins s'ouvrant radialement vers l'extérieur, et un élément intermédiaire de roulement définissant une troisième pluralité de chemins au niveau de la surface radialement externe de celui-ci et une quatrième pluralité de chemins au niveau de la surface radialement interne de celui-ci. Des éléments roulants peuvent être reçus dans les chemins. L'élément intermédiaire de roulement présente une saillie axiale au moins au niveau d'une extrémité de celui-ci qui peut être reçue dans un logement par rapport auquel les éléments externe et interne de roulement peuvent tourner.
