Title (EN) COOL FORMING OF SPLINED TRANSMISSION HUBS
(FR) FORMAGE A FROID DE MOYEUX DE TRANSMISSION CANNELES
Abstract: front page image
(EN)A method for cold forming splined transmission hubs is provided. A blank (10) with an inner surface and an outer surface is secured on a tool insert support member (100). The tool insert support member (100) has an internal spline tooth profile (110) machined into it. A forming roller (120) is inserted inside the blank and then moves radially under pressure until it contacts an inner surface of the blank. A set of teeth (111) are created on the outer surface of the blank (10) and the blank (10) is rotated relative to the forming roller (120) to form an oil reservoir on the inner surface of the blank.
(FR)La présente invention concerne un procédé de formage à froid de moyeux de transmission cannelés. Selon ce procédé, une ébauche (10) présentant une surface interne et une surface externe est fixée sur un élément de support d'insertion d'outil (100). Un profilé à dents cannelé interne (110) est usiné dans cet élément de support d'insertion d'outil (100). Un rouleau de formage (120) est inséré dans l'ébauche et se déplace radialement sous pression, jusqu'à entrer en contact avec la surface interne de l'ébauche. Un ensemble de dents (111) est pratiqué sur la surface externe de l'ébauche (10), puis l'ébauche (10) est mise en rotation par rapport aux rouleaux de formage (120), afin de produire une réserve d'huile à la surface interne de l'ébauche.
