Abstract

L'invention concerne une boîte de vitesses comprenant un engrenage planétaire (3) dont le planétaire interne (2) constitue l'entrée, et le porte-satellites (6) la sortie. Ce porte-satellites est relié à un pignon cylindrique (10) d'un réducteur à pignons cylindriques, ledit pignon cylindrique étant logé dans le logement (5) de la boîte de vitesses par l'intermédiaire d'un support (13). Ce support (13) est disposé dans la zone de denture (12) du pignon cylindrique (10), ce qui permet d'obtenir une boîte de vitesses présentant une longueur totale extrêmement réduite.
