Abstract

L'invention concerne un engrenage centrifuge à entrée provenant de multiples dispositifs d'entraînement, comprenant une roue d'engrenage externe (1) pourvue d'une cavité latérale (11, 13), un rotor (2, 3) monté dans la cavité latérale (11, 13), et un bloc coulissant pouvant coulisser radialement (4) disposé sur le rotor (2, 3). Le rotor (2, 3) est entraîné en rotation par un dispositif d'entraînement, de sorte que le bloc coulissant (4) soit en contact avec la paroi interne de la cavité latérale (11, 13) lorsque la vitesse de rotation du rotor (2, 3) atteint un seuil, entraînant ainsi en rotation la roue d'engrenage externe (1). Inversement, le bloc coulissant (4) se retire lorsque la vitesse du rotor (2, 3) est inférieure au seuil, et la roue d'engrenage externe (1) perd de la puissance et arrête progressivement de tourner. L'invention permet de résoudre les problèmes d'un nombre limité de sources de puissance et d'une installation difficile provoqués par une grande taille radiale d'un dispositif à entrées parallèles de sources de puissance existant. L'engrenage centrifuge permet de mettre en œuvre une entrée synchrone de multiples dispositifs d'entraînement, de même que de réduire la taille radiale, et le rotor (2, 3) ainsi que la roue d'engrenage externe (1) sont en prise souple de façon à empêcher l'impact sur un dispositif de prise lors d'un démarrage brusque, de sorte que la transmission de puissance soit plus stable.
