Abstract

L'INVENTION CONCERNE DES BUTEES ELASTIQUES OU SEMBLABLES, A SUPERPOSITION DE COUCHES ALTERNEES DE MATERIAU RIGIDE ET D'ELASTOMERE. ELLE CONSISTE A EVITER LA DISCONTINUITE DU CAOUTCHOUC SUR LES BORDS DES COUCHES, ET CELA EN NOYANT LE CAOUTCHOUC DANS UNE GAINE D'ELASTOMERE QUI ABSORBE AINSI LES CONTRAINTES MARGINALES. L'EPAISSEUR DE CETTE ENVELOPPE DOIT ETRE CHOISIE CONVENABLE POUR ASSURER L'EFFET CHERCHE. EVENTUELLEMENT ELLE PEUT ETRE EN CAOUTCHOUC DE MODULE DIFFERENT. APPLICATION A DES BUTEES DE PALES D'HELICOPTERES.
