Title
(EN) COMPACT AND HIGH PROPULSION EFFICIENCY TRANSMISSION FOR BOATS AND BOAT EQUIPPED WITH SUCH A TRANSMISSION
(FR) TRANSMISSION COMPACTE ET À GRANDE EFFICACITÉ DE PROPULSION POUR BATEAUX, ET BATEAU ÉQUIPÉ D'UNE TELLE TRANSMISSION
Abstract
(EN)
Transmission (10) for boats of the type comprising a shaft (12) substantially arranged half inside and half outside the hull (13) and having a non-zero projection angle (21), the outer end of said shaft (12) being provided with a propulsion propeller (15); a coupling (17) between the inner end of said shaft (12) and the inverter (25) of the boat being provided; said coupling (17) comprising: a sleeve (34) flanged to said inverter (25) and internally equipped with a straight teeth toothing; - a second sleeve (30) externally provided with a spherical external toothing (31) and fitted on said shaft (12) at said inner end; wherein said spherical toothing (31) of said second sleeve (30) is meshed with the straight teeth toothing of said sleeve (34) flanged to said inverter (25) so as to allow the transmission of movement to said shaft (12) and to absorb alignment errors in the absence of Cardan or homokinetic joints between said shaft (12) and said inverter (25).
(FR)
Cette transmission (10) pour bateaux est du type comprenant un arbre (12) agencé sensiblement pour moitié à l'intérieur et pour moitié à l'extérieur de la coque (13) et possédant un angle de projection non nul, l'extrémité extérieure dudit arbre (12) étant équipée d'une hélice de propulsion (15) ; un accouplement (17) étant agencé entre l'extrémité intérieure dudit arbre (12) et l'inverseur (25) du bateau ; cet accouplement (17) comprenant : un manchon (34) fixé par brides sur ledit inverseur (25) et pourvu intérieurement d'une denture à dents droites ; un deuxième manchon (30) pourvu extérieurement d'une denture extérieure sphérique (31) et monté sur ledit arbre (12) au niveau de ladite extrémité intérieure ; ladite denture sphérique (31) dudit deuxième manchon (30) étant en prise avec la denture à dents droites dudit manchon (34) fixé par brides sur ledit inverseur (25) de manière à permettre la transmission du mouvement audit arbre (12) et à absorber des erreurs d'alignement en l'absence de joints à la Cardan ou homocinétiques entre ledit arbre (12) et ledit inverseur (25).
