Hardening of bearing surfaces of different size crankshaft - comprises two inductor sets, each inductor is adapted for a specific crankshaft having associated transformers, connecting lead, cooling and quenching pipes, etc.

摘要

The bearing surfaces of crankshafts of different sizes are successively hardened by an arrangement of at least two inductor sets, each of inductors adapted to a specific crankshaft type, with associated transformers, electrical connecting leads, cooling and quenching piping and lifting and lowering mechanism. The sets can be moved from a parking position to an operative position, where they can be automatically coupled to the power supply. ADVANTAGE - Acceleration of change-over times.
