Abstract

CET ENGRENAGE EST DU TYPE COMPRENANT UN PIGNON MENANT ET UN PIGNON MENE POURVUS CHACUN D'UNE DENTURE A DENTS SEMBLABLES REGULIEREMENT ESPACEES. IL EST CARACTERISE EN CE QUE LESDITES DENTS SONT SYMETRIQUES, EN CE QUE LE PAS DU PIGNON MENANT EST COMPRIS ENTRE UNE ET DEUX FOIS LE PAS DU PIGNON MENE, ET EN CE QUE L'ARC D'ENGAGEMENT DES DENTS DU PIGNON MENANT DANS LA DENTURE DU PIGNON MENE COMPORTE UN SEGMENT D'ARC PARCOURU LIBREMENT SANS ENTRAINER LE PIGNON MENE ET UN SEGMENT D'ARC D'ENTRAINEMENT LE LONG DUQUEL LA DENT ENGAGEE FAIT AVANCER LE PIGNON MENE D'UN PAS DE SA DENTURE, LES FORMES DES DENTS ETANT TELLES QUE POUR AU MOINS UNE POSITION DU PIGNON MENANT DEUX DE SES DENTS, EMPECHENT LE PIGNON MENE DE SE DEPLACER DANS UN SENS OU DANS L'AUTRE SOUS L'EFFET D'UN COUPLE PERTURBATEUR. L'INVENTION TROUVE UNE APPLICATION AVANTAGEUSE POUR L'ENTRAINEMENT D'UN ROUAGE A PARTIR D'UN MOTEUR PAS A PAS DANS UN MECANISME DE PRECISION.
