Method and apparatus for the hardening of running faces and transition radii of crankshaft offset journals arranged directly one behind the other

摘要

Running faces (1, 2) and transition radii (16) on offset journals (3) of crankshafts (6), in which the offset journals (3) are arranged one behind the other without webs, are hardened according to the method rotationally and simultaneously. The hardening apparatus is designed so that, in correspondence with the number of offset journals (3) arranged directly one behind the other, the same number of inductors (4) are arranged opposite, offset (7) perpendicularly to the axis of rotation (5) of the crankshaft (6).
