Abstract

Procédé caractérisé en ce que l'on réalise le pignon de diamètre intermédiaire (1) en formant un rebord circulaire (5) de chaque coté de son ouverture centrale, on forme, sur l'extrémité libre de la face extérieure de ces rebords, des épaulements (9,10) de diamètre inférieur au diamètre des rebords, on réalise séparément le petit et le grand pignon (2, 3) de la roue libre, ces pignons présentant une ouverture centrale (11, 12) dont le diamètre correspond à celui des épaulements du pignon intermédiaire (1) et on fixe par soudure les bords des ouvertures centrales du petit et du grand pignon sur les épaulements du pignon intermédiaire.Process characterized in that the pinion of intermediate diameter (1) is produced by forming a circular rim (5) on each side of its central opening, on the free end of the outer face of these rims, shoulders (9,10) of diameter smaller than the diameter of the flanges, the small and the large pinion (2, 3) of the freewheel are produced separately, these pinions having a central opening (11, 12) whose diameter corresponds to that of the shoulders of the intermediate pinion (1) and the edges of the central openings of the small and large pinion are fixed by welding to the shoulders of the intermediate pinion.
