Abstract

PURPOSE: To heat the entire rugged surface uniformly and perform uniform hardening by forming a high frequency heating coil into the shape that a part thereof corresponding to a projecting part copies the projecting part axially and the other part copies the same circumferentially.
CONSTITUTION: Partial shapes of a high frequency heating coil 1 corresponding to the projecting part 2a of a shaft 2 having rugged parts are formed into the shape wherein one part has the shape copying the projecting part aixially like a copying part 1a and the other copies the same circumferentially like a copying part 1b. High frequency electricity of a relatively low frequency (≤20kHz) is conducted to this coil 1, whereby the shaft is heated. By this method, the part where offsetting of magnetic fluxes is produced and the part where it is not are produced, and the heating of the projecting part is accomplished in the same manner as for the other parts, whereby the entire part is uniformly heated.
