Abstract

L'INVENTION CONCERNE UNE POULIE DENTEE A UTILISER AVEC UNE COURROIE DENTEE ET FLEXIBLE. SELON L'INVENTION, LES DENTS 21 DE LA POULIE SE COMPOSENT DE BOUTS CONNECTES PAR DES CAVITES 22, CHAQUE BOUT AYANT UN CONTOUR EN SECTION TRANSVERSALE LONGITUDINALE PARTIELLEMENT COMPOSE DE DEUX ARCS DE CERCLE 25, QUI ONT DES CENTRES DE COURBURE 26, 27 DECALES L'UN DE L'AUTRE, LE CENTRE DE COURBURE DE CHAQUE ARC ETANT PLACE DU MEME COTE DE L'AXE 28 QUE SON ARC RESPECTIF, LA PARTIE LA PLUS EXTERNE DU BOUT DE LA DENT JOIGNANT LES DEUX ARCS FORMANT UN SEGMENT DE LIGNE 31, DONT LA LONGUEUR EST COMPRISE ENTRE 5 ET 100 DE LA LARGEUR DE LA DENT DE LA COURROIE AVEC LAQUELLE LA POULIE DEVRA ETRE UTILISEE. L'INVENTION S'APPLIQUE NOTAMMENT AUX SYSTEMES D'ENTRAINEMENT POSITIF.THE INVENTION RELATES TO A TOOTHED PULLEY FOR USE WITH A TOOTHED AND FLEXIBLE BELT. ACCORDING TO THE INVENTION, THE TEETH 21 OF THE PULLEY CONSIST OF ENDS CONNECTED BY CAVITIES 22, EACH END HAVING A CONTOUR IN LONGITUDINAL CROSS-SECTION PARTLY CONSISTS OF TWO CIRCLE ARCS 25, WHICH HAVE CENTERS OF CURVATURE 26, 27 DECALS L 'ONE OF THE OTHER, THE CENTER OF CURVATURE OF EACH ARC BEING PLACED ON THE SAME SIDE OF AXIS 28 AS ITS RESPECTIVE ARC, THE OUTSIDE PART OF THE END OF THE TEETH JOINING THE TWO ARCS FORMING A SEGMENT OF LINE 31, THE LENGTH OF WHICH IS BETWEEN 5 AND 100 OF THE TOOTH WIDTH OF THE BELT WITH WHICH THE PULLEY SHOULD BE USED. THE INVENTION APPLIES IN PARTICULAR TO POSITIVE DRIVE SYSTEMS.
