Abstract

L'invention concerne l'atténuation des vibrations d'un système tournant. Selon l'invention, un élément d'absorption des vibrations 32 comprenant essentiellement un poids oscillant placé au sommet d'un ressort vertical, est accouplé rigidement au socle 20 d'un palier 16 sur lequel s'exerce une force résultant du déséquilibre d'une masse tournante. Application au rotor des soufflantes de centrale thermique.
