Equipment for inductive hardening of directly adjacent bearing surfaces of a crankshaft

摘要

The appts. for electroinductive hardening of directly adjacent bearing surfaces (2a, 3a) of a crankshaft (1) has inductors (10, 11) with each initial inductor side branch (12, 14) for each directly adjacent bearing surfaces (2a, 3a) in a length (L') which at max. equals the shrouding arc (U) of the two surfaces (2a, 3a). In at least one of the inductors (10, 11) the second inductor branch (13, 15) has a greater length (L'') than the shrouding arc (U).
