Abstract

L'invention se rapporte aux groupes turbine-générateur du type bulbe. Dans cette unité de montage, le stator 3 du générateur présente une surface d'alésage intérieure servant de surface de glissement pour les segments de centrage 5 fixés au dôme amont 2 du groupe. Ces surfaces de glissement sont destinées à permettre les translations axiales produites sous l'effet des dilatations thermiques. La fente entre le stator 3 et le dôme 2, qui est nécessaire pour le montage et pour l'absorption des dilations thermiques, est fermée à l'extérieur par une garniture d'étanchéité 9, présentant des languettes semi-circulaires qui s'encastrent dans des rainures correspondantes des éléments 2 et 3. Cette garniture est comprimée sur les éléments 2 et 3 par un bandage de serrage extérieur 10 et elle est soutenue dans la fente par des supports fixés à l'élément 2, à l'élément 3 ou aux segments 5. L'invention s'applique notamment aux groupes bulbes de plusieurs mètres de diamètre.
