Abstract

L'invention concerne un démultiplicateur à plusieurs étages dans lequel un premier étage de démultiplication est réalisé sous forme d'engrenage planétaire (8) comprenant une première roue planétaire (22) pouvant être entraînée, ainsi que plusieurs premiers satellites (20) qui sont logés rotatifs dans un premier porte-satellites logé rotatif (10) et qui s'engrènent simultanément dans la première roue planétaire (22) et dans une première couronne (16) également logée rotative. Un deuxième étage de démultiplication comprend au moins deux pignons (4, 6) qui s'engrènent tous deux à des emplacements différents sur la circonférence d'une grande roue (2), le premier pignon (4) étant solidaire en rotation avec le premier porte-satellites (10) et le deuxième pignon (6) étant en relation d'entraînement avec la première couronne (16) par le biais d'un étage d'engrenage (12, 14) inversant le sens de rotation. L'invention est caractérisée en ce qu'on a au moins un autre démultiplicateur similaire, les deux démultiplicateurs présentant une grande roue commune (2).
