Title (EN) PROCESS AND DEVICE FOR MANUFACTURING HARDENED SURFACES BY SECOND FUSION OF A PART COMPRISING VARIABLE RADIUS OF CURVATURE,IN PARTICULAR OF CAMES OF A CAME SHAFT IN INTERNAL COMBUSTION MACHINES
(FR) PROCEDE ET DISPOSITIF DE FABRICATION DE SURFACES TREMPEES PAR DEUXIEME FUSION D"UNE PIECE COMPRENANT DES RAYONS DE COURBURE VARIABLES, EN PARTICULIER DE CAMES D"UN ARBRE A CAMES DE MACHINE A COMBUSTION INTERNE
Abstract: front page image
(EN)The surface to be hardened is passed before an energy source causing the second fusion while maintaining constant, at least approximately, the value of the conducted energy with respect to the volume of the part to be remelted. This can be obtained by controlling the output of the energy source according to the radius of curvature. In a device for the hardening by second melting of cames of came shaft (3) by means of an electric arc, the output power of a generator (21) is consequently controlled by means of a control circuit (20) or a switch.
(FR)Selon le procede, in fait passer la surface a tremper devant une source d"energie provoquant la deuxieme fusion en maintenant la valeur de l"energie amenee par rapport au volume de la piece a refondre. On peut obtenir ceci en commandant la puissance de la source d"energie en fonction du rayon de courbure. Dans un dispositif pour la trempe par deuxieme fusion de cames d"arbres a cames (3) au moyen d"un arc electrique, on commande en consequence la puissance de sortie d"une generatrice (21) au moyen d"un circuit de commande (20) ou d"un commutateur.
