Abstract

Metodo per la tempra induttiva di superfici (7, 8) di scorrimento e raggi di raccordo su alberi a gomito (4), sui quali i perni di manovella (5, 6) per l'alloggiamento delle bielle sono disposti in diretta successione con differente posizione angolare su piani perpendicolari rispetto all'asse di rotazione, in cui gli induttori (1) adiacenti fra di loro sono accostati dallo stesso lato ai perni di manovella (5, 6). I due induttori (1) sono distanti fra di loro nella zona fra i due perni di manovella (5, 6) disposti in diretta successione.
