ABSTRACT:- In general, mechanics put in work to assure reliability and the everlastingness of machines that they conceive. And yet, of defaults (distortion, cracks and irregularity of quenched depths) occur, soon of uncertain way, soon of repeated way. After have treated the superficial quench by induction of the simple geometry pieces (cylindrical) [1], we propose to treat the quenching contour of toothed pieces type gearings, toothed wheels, therefore…, more precisely the profile of teeth of a wheel. In this paper we will present an approach interesting based on the research of an optimal frequency of the generator. We make call to three varied techniques: Quenching of contour mono frequency, Quenching bi-frequency and Quenching bi-frequency bilies to choose the best description of the contour quenched.
Key Words: Inductive heating, Quenching of contour, optimal frequency, gearing
