Abstract

L'invention concerne les accouplements à roue libre. Accouplement à roue libre entre un arbre menant et un arbre mené comprenant des moyens d'empêchement qui empêchent automatiquement l'engrènement tant que la vitesse de rotation des arbres n'est pas synchronisée. Ces moyens d'empêchement comprennent un palier à billes dont le roulement roule dans les gorges circonférentielles de chemins de roulement intérieur et extérieur disposés respectivement sur une première et une deuxième partie de l'accouplement. Des encoches, formées dans l'un des chemins de roulement permettent un déplacement axial relatif des parties de l'accouplement par déplacement des billes dans les encoches. Application notamment aux systèmes de transmission pour rotors d'hélicoptères.
