Abstract

On réalise les pignons (9, 10, 11) de la roue libre par une opération d'emboutissage-découpage d'une plaque de métal, on soude les pignons 9-1, 10, 11) l'un à l'autre, on usine les parties concaves (9-1-, 11-1-) des deux emboutis et on taille les chants des orifices (13) des pignons soudés.
