Abstract
CE MECANISME A BILLES DE PORTEE, POUVANT ETRE MUNI D'UN DISPOSITIF DE RECYCLAGE DES BILLES, COMPREND UNE VIS, OU ELEMENTS INTERIEUR DE PORTEE, COMPORTANT TROIS GORGES HELICOIDALES 1, 2, 3 ET UN ECROU OU ELEMENT EXTERIEUR DE PORTEE A TROIS GORGES HELICOIDALES COOPERANT AVEC CELLES DE LA VIS, DES BILLES ETANT INSEREES ENTRE LES GORGES ASSOCIEES DE CES DEUX ELEMENTS. LES DIAMETRES DE GORGES ET DE BILLES ADOPTES SONT EGAUX AU DIAMETRE NORMALEMENT DETERMINE POUR LE PAS D'UNE GORGE UNIQUE CORRESPONDANT A L'ECARTEMENT DE DEUX GORGES VOISINES DE LA SERIE. CET AGENCEMENT PERMET LA DIMINUTION DE DIMENSION DE GORGE ET EVITE AINSI L'AFFAIBLISSEMENT EXCESSIF DE LA VIS, PARTICULIEREMENT LORSQUE CELLE-CI EST DE FAIBLE DIAMETRE.
