Abstract

EMBRAYAGE ELECTROMAGNETIQUE A PATINAGE LIMITE. L'EMBRAYAGE COMPORTE UN ORGANE MENANT 12 PORTANT UNE BOBINE ELECTROMAGNETIQUE 32 ET UN ORGANE MENE 36 MONTE A ROTATION SUR L'ORGANE MENANT ET ENTOURANT LA BOBINE DE FACON A FORMER AVEC LES PIECES POLAIRES 46, 48 DE CETTE DERNIERE UN ENTREFER 50. UN COLLIER D'ACCOUPLEMENT 52 EST DISPOSE DANS L'ENTREFER ET COMPORTE UNE BANDE INTERIEURE 54 EN MATIERE MAGNETIQUE RACCORDEE A UNE BANDE EXTERIEURE ELASTIQUE 56 QUI PORTE UN REVETEMENT DE FRICTION 64 EN APPUI DE FRICTION CONTRE L'ORGANE MENE DE SORTE QUE, LORSQUE LA BOBINE EST EXCITEE, LA BANDE INTERIEURE S'APPLIQUE CONTRE L'ORGANE MENANT, ENTRAINANT L'ORGANE MENE PAR L'INTERMEDIAIRE DU REVETEMENT DE FRICTION QUI PERMET UN CERTAIN PATINAGE EN CAS DE SURCHARGE. APPLICATION A UN EMBRAYAGE DE VENTILATEUR DE MOTEUR A COMBUSTION INTERNE.
