Abstract
Une cage (5) est intercalée entre la vis et l’écrou pour contenir les billes (3) dans des alvéoles (6) séparés. La cage (5) est retenue axialement par des butées pour rester toujours entre la vis et l’écrou, ainsi que les billes (3). Aucune recirculation des billes (3) n’est nécessaire. La cage (5) oblige les billes (3) à suivre les mouvements de rotation de la pièce tournante. Figure pour l’abrégé : Figure 2.A cage (5) is inserted between the screw and the nut to contain the balls (3) in separate cells (6). The cage (5) is retained axially by stops to always remain between the screw and the nut, as well as the balls (3). No recirculation of the balls (3) is necessary. The cage (5) forces the balls (3) to follow the rotational movements of the rotating part. Figure for abstract: Figure 2.
