Abstract

L'invention concerne un joint en élastomère pour arbres en rotation relative. Ce joint 1 comporte, sur la partie tronconique de sa lèvre d'étanchéité adjacente à l'arête de contact 6, deux séries de nervures 7, 9 en forme d'arcs, les deux séries étant décalées l'une par rapport à l'autre et de concavités inversées. Application : joints pour tous arbres, notamment pour les moteurs de véhicules ou autres.The invention relates to an elastomeric seal for shafts in relative rotation. This seal 1 comprises, on the frustoconical part of its sealing lip adjacent to the contact edge 6, two series of ribs 7, 9 in the form of arcs, the two series being offset one with respect to the other and inverted concavities. Application: seals for all shafts, in particular for vehicle engines or others.
