Abstract

L'invenzione riguarda un dispositivo per il riscaldamento elettroinduttivo e la successiva tempra ai fini dell'indurimento delle superfici di supporti di manovella che si toccano immediatamente uno con l'altro di un albero a manovelle mediante due induttori disposti in posizione diametralmente opposta uno all'altro sul pezzo in lavorazione, dei quali di volta in volta uno è associato ad uno dei due supporti di manovella e la cui larghezza è minore della larghezza della gola relativa ad un supporto di manovella.Caratterizzante dell'invenzione è il fatto che la superficie di azione di forma arcuata (19) degli induttori (12) è più larga del dorso del supporto di. manovella (11c) e presenta al massimo la stessa lunghezza (1) dell'arco di sovrapposizione (20) dei supporti di manovella (11a, 11b).The invention relates to a device for electro-inductive heating and subsequent hardening for the purpose of hardening the surfaces of crank supports which immediately touch each other on a crankshaft by means of two inductors arranged in a diametrically opposite position one to the other. another on the workpiece, of which one from time to time one is associated with one of the two crank supports and whose width is less than the width of the groove relative to a crank support. Characterizing of the invention is the fact that the surface of arc-shaped action (19) of the inductors (12) is wider than the back of the support of. crank (11c) and has at most the same length (1) as the overlapping arc (20) of the crank supports (11a, 11b).
