Abstract

PROCEDE DE FABRICATION D'UN ECROU COMPORTANT UN ANNEAU D'ETANCHEITE. LE PROCEDE PERMET D'ELIMINER L'OPERATION COUTEUSE D'USINAGE D'UNE CONTRE-DEPOUILLE DANS LE CONTRE-ALESAGE DE L'EBAUCHE D'ECROU POUR OBTENIR UN MOYEN DE MAINTIEN EN PLACE DE L'ANNEAU D'ETANCHEITE. CELA EST OBTENU EN LAISSANT UNE QUANTITE PREDETERMINEE DE MATERIAU EN EXCES EN SAILLIE AUTOUR DE LA PERIPHERIE DU CONTRE-ALESAGE LORSQUE CELUI-CI EST INITIALEMENT FORME A FROID. LORSQUE LA SURFACE D'APPUI EST ENSUITE APLATIE AU COURS D'UNE AUTRE ETAPE DE FORMAGE A FROID, LE MATERIAU EN EXCES EST ENTRAINE RADIALEMENT VERS L'INTERIEUR, CE QUI REDUIT LEGEREMENT LE DIAMETRE DU CONTRE-ALESAGE A LA SURFACE D'APPUI DE L'ECROU. L'ELIMINATION DE L'OPERATION DE CONTRE-DEPOUILLE SE TRADUIT EGALEMENT PAR UN ECROU QUI PEUT SUPPORTER UN COUPLE ET DES CHARGES PLUS ELEVES. APPLICATION A LA FABRICATION DES ECROUS ETANCHES.
