APPARATUS FOR INDUCTIVE HARDENING CRANKSHAFTS WITH CRANK PINS HAVING A HOLLOW GROUND RADIUS

摘要

A method for the inductive hardening of working surfaces and transition radii on crankshafts in which, to receive connecting rods, crank pins are disposed directly one after another at different angular attitudes in planes at right-angles to the axis of rotation is disclosed. By the subject invention, adjacently disposed inductors are applied against the crank pins from the same side. Both inductors are disposed in the region between the two serially disposed crank pins and are spaced apart from each other.
