Abstract
Le dispositif comporte au moins deux variateurs de vitesse en parallèle ayant chacun un rotor 12 d'entrée de couple et deux rotors 10, Il de sortie de couple, lesquels sont reliés par des jeux de galets plats 14, 13 en roulement de frottement sur leurs surfaces toroïdales 10a, 11a et 12a, 12b; l'inclinaison des structures 15, 16 de paliers des galets modifie le rapport de transmission de l'entree à la sortie. Le disque 12 a une denture extérieure 30 constituant l'élément de sortie. Les disques 10 et 11 sont calés sur l'arbre creux 18 constituant l'élément d'entrée du couple exercé par la denture 34 depuis la roue 35 liée aux tocs 38 qui sont entraînés par un moteur. Le dispositif est commande hydrauliquement. Ce dispositif est notamment destiné à entraîner un appareil auxiliaire d'aéronef en vitesse constante à partir du moteur principal.
