Abstract

L'INVENTION FOURNIT UN DISPOSITIF D'INSONORISATION POUR ABSORBER LES VIBRATIONS ACOUSTIQUES DANS UNE ROUE DENTEE. IL COMPREND UNE CAVITE ANNULAIRE 5 FORMEE DANS LE CORPS 2, 4 DE LA ROUE 1 ET DANS LAQUELLE SONT LOGES UN ANNEAU 7 D'ELASTOMERE ET UNE BAGUE DE RETENUE 6. L'ANNEAU EST COMPRIME ENTRE DES FACES CYLINDRIQUES TOURNEES L'UNE VERS L'AUTRE DE LA BAGUE 6 ET DU CORPS 2, 4. LA BAGUE PEUT ETRE IMMOBILISEE DANS LA CAVITE PAR DEFORMATION PLASTIQUE D'UN PROLONGEMENT ANNULAIRE 9 QU'ELLE PRESENTE DANS UNE DEPOUILLE D'UNE DES FACES QUI DELIMITENT LA CAVITE.THE INVENTION PROVIDES A SOUNDPROOFING DEVICE FOR ABSORBING ACOUSTIC VIBRATIONS IN A GEAR. IT INCLUDES AN ANNULAR CAVITY 5 SHAPED IN BODY 2, 4 OF WHEEL 1 AND IN WHICH ARE HOUSED AN ELASTOMER RING 7 AND A RETAINING RING 6. THE RING IS COMPRESSED BETWEEN CYLINDRICAL FACES TURNED TOWARDS THE ONE. 'OTHER FROM THE RING 6 AND THE BODY 2, 4. THE RING CAN BE IMMOBILIZED IN THE CAVITY BY PLASTIC DEFORMATION OF AN ANNULAR EXTENSION 9 THAT IT PRESENTS IN A STRIP OF ONE OF THE FACES THAT DELIMINE THE CAVITY.
