Abstract

Dispositif de maintien et d'étanchéité d'aubes de turbine. Une plaque annulaire porte d'un même côté vers son bord extérieur des tétons et vers son bord intérieur des crochets. Le disque de rotor porte sur son bord inférieur une dentelure, le sommet des dents étant conformé pour coopérer avec la surfacè interne des crochets. Les aubes portent sur leur rebord des logements. Deux aubes voisines forment un logement dans lequel vient se placer les tétons lorsque les crochets coopèrent avec les dents. Les tétons sont portés par des languettes découpées radialement dans la plaque annulaire. Application au maintien des aubes de turbine.
