Abstract

L'invention concerne un amortisseur à poulie pour amortir des mouvements d'oscillation d'un arbre d'entraînement. L'amortisseur à poulie présente une poulie pour l'entraînement d'un moyen de traction, notamment d'une courroie de traction, et un flasque d'entrée pouvant être relié de manière solidaire en rotation à l'arbre d'entraînement. Le flasque d'entrée présente au moins un moyen de fixation, notamment une ouverture pour relier le flasque d'entrée à l'arbre d'entraînement. En outre, un amortisseur d'oscillations, notamment réalisé de manière découplée pour les mouvements d'oscillation, est disposé de manière à effectuer le transfert à la poulie d'un couple introduit par le biais du flasque d'entrée. Entre la poulie et le flasque d'entrée est réalisé un palier pour supporter la poulie sur le flasque d'entrée. Selon l'invention, le palier est disposé dans la direction radiale entre le moyen de fixation et un axe de rotation du flasque d'entrée. De ce fait, il est possible de se passer d'un moyeu relié à l'arbre d'entraînement et de fabriquer l'amortisseur à poulie en conséquence, sous forme réduite et compacte. De ce fait, on obtient un amortisseur à poulie permettant une installation simplifiée et des coûts de fabrication réduits.
