The invention relates to a system for providing a mechanical and electrical connection between the ends of two essentially-coaxial shafts (1 and 2), whereby each shaft end comprises a groove (11, 12) close to an axial end extension (17 and 8; 18 and 9). Moreover, the aforementioned ends are connected inside a sleeve (10) comprising: a first annular shoulder (13) having a shape that is complementary to that of the groove of the first shaft, such that there is no clearance therebetween; a second annular shoulder (14) having a shape that is complementary to that of the groove (12) of the second shaft, but with a clearance therebetween; and a cavity (16) which is intended to receive the shaft ends, said cavity having an axial height which is greater than the sum of the axial heights of the axial end extensions (17 and 8; 18 and 9). The invention is characterised in that the axial end extensions (17 and 8; 18 and 9) of the two shafts are in permanent mechanical and electrical contact via an elastic conducting means (7).
Système de liaison mécanique et électrique entre les extrémités de deux arbres (1 et 2) sensiblement coaxiaux, dans lequel chaque extrémité d~arbre comprend un gorge (11, 12) à proximité d~un prolongement axial d~extrémité (17 et 8 ; 18 et 9) ; lesdites extrémités sont réunies à l~intérieur d~un manchon (10) muni : d~un premier épaulement annulaire (13), dont la forme est complémentaire et sans jeu de cell de la gorge du premier arbre ; d~un deuxième épaulement annulaire (14), dont la forme est complémentaire mais avec jeu de celle de la gorge (12) du deuxième arbre ; d~une cavité (16) destinée à recevoir lesdites extrémités d~arbre, dont la hauteur axiale est supérieure à la somme des hauteurs axiales des prolongements axiaux d~extrémités (17 et 8 ; 18 et 9) ; et en ce que les prolongements axiaux d~extrémité (17 et 8 ; 18 et 9) des deux arbres restent en contact mécanique et électrique permanent grâce à un moyen élastique conducteur (7).
