Abstract

Ce système de lames hélicoïdales sur tuyau tubulaire (10) pourvu d'un coupleur (16). Il comporte un manchon (60 ou 70) prenant à l'intérieur ou à l'extérieur d'une extrémité (36) d'un arbre (12) de façon à y former une épaisseur de paroi renforcée (W3). Ce manchon est reçu dans un collier (52) solidaire d'une extrémité (40) d'un autre arbre (14). Les deux arbres peuvent être réunis par un unique boulon (50) passé au travers du manchon (60 ou 70), de l'extrémité (36) de l'arbre (12) et du collier (52) de façon à transmettre un couple important sans qu'il y ait besoin d'un boulonnage complexe.
