Abstract

Turbine possédant une aube mobile de sorte que même si la longueur est raccourcie ou même si de telles aubes sont utilisées pour une turbine à faible vitesse de rotation, les aubes peuvent être jointes de manière serrée, sans espace entre elles, si bien qu'il est possible d'obtenir un fort effet d'atténuation des vibrations. Ladite aube mobile de turbine est caractérisée en ce qu'un élément de jonction placé face à des aubes adjacentes possède une face périphérique circonférentielle en forme de pente inclinée dans le sens axial par rapport au sens circonférentiel de la turbine, en ce qu'au moins une pente faisant face aux aubes adjacentes est dotée d'une rainure qui s'étend dans le sens d'inclinaison, et en ce qu'une broche de jonction auxiliaire est introduite dans la rainure tandis qu'un couple de torsion est appliqué sur la partie de l'aube mobile encastrée dans un disque, de manière à restreindre ainsi le retour de torsion de ladite partie d'aube mobile.
