Abstract

L'invention concerne un accouplement élastomère comprenant deux éléments d'accouplement, un procédé de fabrication d'une bague de pression destinée audit accouplement élastomère et un dispositif permettant de mettre en œuvre ledit procédé. On connaît déjà un accouplement élastomère dans lequel est serré au moins un corps élastomère, au moins un élément d'accouplement étant muni d'une bague de pression métallique pressée axialement contre une section de serrage du corps élastomère. Selon l'invention, la bague de pression est munie sur sa surface frontale orientée vers la section de serrage de profilés qui sont produits conjointement à la fabrication de la bague de pression lors d'un processus de coulée ou de forgeage en une étape. L'invention est également appliquée à la transmission de couple pour des mécanismes d'entraînement de bateaux.
