Abstract

TRANSMISSION A ROUES DE FRICTION POUR TRANSMETTRE AVEC UN RAPPORT VARIABLE EN CONTINU UN MOUVEMENT DE ROTATION ENTRE UN ARBRE D'ENTREE 1 ET UN ARBRE DE SORTIE 12 COAXIAL, QUI COMPREND UNE ROUE DE FRICTION CONCENTRIQUE SOLIDAIRE DE L'ENVELOPPE OU DU BOITIERQUI PRESENTE DEUX COURONNES DE FRICTION 7, 8 AYANT CHACUNE UNE SURFACE DE TRANSMISSION. IL EST PREVU COMME ORGANE DE SORTIE UNE SECONDE ROUE DE FRICTION 9 MONTEE CONCENTRIQUEMENT SUR L'ARBRE DE SORTIE 12, QUI COMPREND DEUX COURONNES DE FRICTION 10, 11 DONT L'ESPACEMENT AXIAL MUTUEL EST VARIABLE ET QUI COMPORTENT CHACUNE UNE SURFACE DE TRANSMISSION 34 SUR LAQUELLE LA BAGUE DE FRICTION 4 ROULE LE LONG D'UNE SECONDE SURFACE DE TRANSMISSION CONIQUE 31, LES REGIONS DE TRANSMISSION ENTRE LA BAGUE DE FRICTION 4 ET LA PREMIERE ROUE DE FRICTION EXTERIEURE 6 AINSI QUE LA SECONDE ROUE DE FRICTION INTERIEURE 9 ETANT DECALEES ENTRE ELLES DE 180.
