Abstract

L'invention concerne le génie mécanique et peut s'utiliser en génie mécanique, dans la fabrication de machines-outils et dans d'autres industries lorsqu'il est nécessaire d'accélérer la rotation de l'arbre de support en fonction de la charge. L'invention permet d'effectuer des changements sans provoquer d'à-coups des mouvements de transmission, sans sortir les arbres de l'engrenage ni sans faire peser d'autres parties d'entraînement sur les arbres entraîné et d'entraînement. Selon l'invention, l'engrenage comprend des arbres de sortie et d'entrée avec des roues solaires, des routes dentées centrales, des roues planétaires et un porte-satellites. Un porte-satellites de premier étage est réalisé avec la roue centrale de deuxième niveau, un porte-satellites de deuxième étage est réalisé avec la roue centrale de premier niveau, et les roues planétaires de premier étage et/ou les roues planétaires de deuxième étage sont réalisés avec une couronne double.
