Abstract

Dans le système selon la présente invention, l'arbre (4) de la machine rotative comprend une surface cylindrique comportant sur toute sa circonférence des cannelures (17) à bords vifs, de très faible profondeur, ces cannelures étant réparties de façon uniforme et équidistante de manière à former un bout d'arbre cylindrique cannelé dont l'intérieur comprend un alésage tronconique (20) coopérant avec un élément d'expansion tronconique correspondant (22) solidaire d'une des extrémités d'une barre de traction (23) pour bloquer la surface d'accouplement cylindrique (7) de l'arbre contre la surface d'accouplement cylindrique (6) du corps du rotor par interaction radiale.
