Title (EN) SUPPORT TOOL FOR DEEP ROLLING CRANKSHAFT FILLETS
(FR) OUTIL DE SUPPORT POUR FORMAGE DE CONGES DE VILEBREQUINS PAR ECRASEMENT PROFOND AU ROULEAU
Abstract:
(EN) Deep rolling equipment for cold working fillet radii of annular undercuts (F, F') on opposite sides of crankshaft journals has pairs of jaws (42, 43) movable between an open position for receiving the crankshaft journals and a closed position for rolling the fillets. The upper jaw (140) mounts fillet rolling tools (146, 146') for high load rolling engagement in the undercuts. The lower tool (141) has a pair of support rollers (170) with annular journal support portions (174, 177) and annular flanges (181, 183) outboard of the support portions with large diameters which engage in the undercuts and limit the lateral movement of the crankshaft with respect to the rolling and support tools.
(FR) Equipement d'écrasement profond pour formage à froid de l'arrondi des congés formant les dégagements de pied (F, F') annulaires sur les côtés opposés des tourillons de vilebrequins. Cet équipement comporte des paires de mâchoires (42, 43) pouvant être déplacées entre une position ouverte, pour recevoir les tourillons du vilebrequin, et une position fermée, pour former les congés. La mâchoire supérieure (140) supporte des outils de formage (146, 146') de congés qui entrent en contact avec les dégagements de pied pour produire un écrasement sous forte charge. L'outil inférieur (141) présente une paire de rouleaux de support (170) comportant des parties de support (174, 177) annulaires pour les congé, et des rebords (181, 183) annulaires de stabilisation à l'extérieur des parties de support. Ces rebords présentent des diamètres importants et viennent s'engager dans les dégagements de pied pour limiter le mouvement latéral du vilebrequin par rapport aux outils d'écrasement et de support.
