Abstract
Il s'agit d'une poulie comportant en regard l'un de l'autre un flasque fixe 12 et un flasque mobile 20, le flasque mobile 20 étant soumis à un diaphragme 21 qui, prenant appui sur une pièce d'appui 25, le sollicite en direction du flasque fixe 12. Suivant l'invention, le diaphragme 21 est centré sur la pièce d'appui 25 à la faveur des ergots 30 que présente celle-ci pour son entraînement en rotation, et le flasque mobile 20 est centré sur le diaphragme 21, à la faveur de blocs d'engagement 33 que présente ce dernier pour son entraînement en rotation, en sorte que le flasque mobile 20 est suspendu par sa périphérie au diaphragme 21. Application aux poulies pour variateurs de vitesse.
