Abstract

See full text

Systems and methods are presented for automated induction hardening of crankshaft bearings while controlling the crankshaft TIR, in which one or more first bearings are hardened by induction heating and quenching, followed by measurement of the crankshaft TIR. The measured TIR is then evaluated and one or more second bearings are hardened using a second induction heating power profile and a second quench flow profile, at least one of which is selectively adjusted according to the measured crankshaft TIR. In this manner, the hardening of the second bearing(s) can counteract any bending or warpage caused by the first hardening process to control the resulting final TIR of the crankshaft.
