Abstract

L’invention concerne un système de transmission de puissance (10) entre un organe d’entrée (20) mobile en rotation autour d’un premier axe (X) de référence, et un organe de sortie (30) mobile en rotation autour d’un deuxième axe (X’) de référence, les premier et deuxième axes (X, X’) étant non coplanaires, le système de transmission (10) comprenant un organe intermédiaire (40) entrainée par l’organe d’entrée (20) en translation par rapport à ce dit organe d’entrée (20) selon le premier axe (X) au moyen d’une première transmission (50) de type liaison hélicoïdale, et entraînant en rotation l’organe de sortie (30) au moyen d’une deuxième transmission (60) dentée, le système de transmission (10) étant caractérisé en ce qu’il comprend au moins un premier patin (71) muni de corps roulants (73) pour rouler sur une première piste (41) de l’organe intermédiaire (40) et configuré pour être disposé entre la première piste (41) de l’organe intermédiaire (40) et un premier chemin de roulement (81) fixe de sorte à assurer une reprise d’efforts. (Fig.1)The invention relates to a power transmission system (10) between an input member (20) movable in rotation about a first reference axis (X), and an output member (30) movable in rotation about it. 'a second reference axis (X'), the first and second axes (X, X ') being non-coplanar, the transmission system (10) comprising an intermediate member (40) driven by the input member (20 ) in translation with respect to said input member (20) along the first axis (X) by means of a first transmission (50) of the helical connection type, and driving the output member (30) in rotation to the means of a second toothed transmission (60), the transmission system (10) being characterized in that it comprises at least a first shoe (71) provided with rolling bodies (73) for rolling on a first track (41) of the intermediate member (40) and configured to be disposed between the first track (41) of the intermediate member (40) and a first raceway (81) fixed so as to ensure a recovery of efforts. (Fig. 1)
