Abstract

L'invention concerne une transmission (4) comportant un engrenage planétaire (13), un arbre d'entraînement (5) et un arbre de sortie (6), l'arbre de sortie (6) étant raccordé à un dispositif d'entraînement destiné à être entraîné. Selon l'invention, une transmission (4) est équipée d'un engrenage planétaire (13), en particulier pour une éolienne (1), ladite transmission présentant une structure compacte et un poids plus faible par rapport aux transmissions connues. Ceci est obtenu par le fait que l'engrenage planétaire (13) est un engrenage épicycloïdal, et par le fait qu'un premier et un deuxième arbre de l'engrenage épicycloïdal sont accouplés à l'arbre d'entraînement (5) et qu'un troisième arbre est accouplé à l'arbre de sortie (6).
