Abstract

Dans les systèmes de propulsion marine semi-hors-bord antérieurs, la puissance est transmise par un aménagement d'embrayages, d'engrenages coniques et d'arbres d'hélice situé au-dessous de la surface de l'eau, ce qui limite le couple pouvant être transmis, notamment pour de grands bateaux commerciaux. La présente invention concerne un arbre extérieur conçu pour dépasser les limitations de puissance en chevaux et de couple imposées par l'état actuel de la technique. Pour atteindre ces objectifs, l'arbre extérieur a été conçu de manière à incorporer un mécanisme (40) de transmission par chaîne à rouleaux multibrins, qui remplace le dispositif d'engrenages coniques classique. Le recours à un mécanisme de transmission par chaîne dans cette application permet d'accroître la durabilité de l'arbre extérieur, et de maintenir en même temps un bon profil aérodynamique de l'enveloppe (43) extérieure.
