Abstract

L'invention concerne les dispositifs d'amortissement des vibrations. Elle se rapporte à un dispositif qui comprend deux amortisseurs 1, 1' destinés à supprimer les vibrations d'une lame 24 de scie. Ces amortisseurs comprennent, du côté de la lame de scie, une surface poreuse qui forme un palier pneumatique et amortit les vibrations. Les deux amortisseurs 1, 1' sont articulés sur des axes 7, 7' et s'écartent de la lame de scie lorsque de l'air sous pression n'est pas disponible. Application à la réduction du bruit des machines d'usinage.
