Abstract
a. Dispositif propulseur pour bateau muni d'une hélice de surface entraînée par un moteur disposé dans le bateau et par l'intermédiaire d'une ligne d'arbre guidée à travers la plaque arrière du bateau. b. Dispositif caractérisé en ce que la ligne d'arbre est divisée, au moins dans la zone de la plaque arrière, la partie de la ligne d'arbre disposée à l'extérieur et portant l'hélice étant montée indépendamment pour tourner dans un bras porteur 2 fixé rigidement par une plaque de bridage 27 sur le bateau ou sur sa plaque arrière, un palier de butée d'hélice étant disposé dans la plaque de bridage de telle manière que la poussée de l'hélice soit transmise à la plaque de bridage et par suite au bateau uniquement par des eléments rigides. c. Dispositif applicable notamment aux bateaux de plaisance.at. Propulsion device for a boat provided with a surface propeller driven by a motor arranged in the boat and by means of a shaft line guided through the back plate of the boat. b. Device characterized in that the shaft line is divided, at least in the area of the rear plate, the part of the shaft line arranged outside and carrying the propeller being independently mounted to rotate in a supporting arm 2 fixed rigidly by a clamping plate 27 on the boat or on its back plate, a propeller thrust bearing being disposed in the clamping plate such that the thrust of the propeller is transmitted to the clamping plate and consequently to the boat only by rigid elements. vs. Device applicable in particular to pleasure boats.
