Presentation focuses on recent inventions and innovations (last 4-6 years) in induction hardening of gears and gear-like components, including but not limited to:
– “Know-how” in controlling distortion of induction hardened gears.
– Simultaneous dual-frequency induction hardening.
– Advanced induction hardening process recipes when hardening small and medium size gears.
– Novel inductor designs to minimize a distortion when induction hardening of hypoid and spiral bevel gears.
– IFP technology for induction gear hardening.
– Induction tempering and stress relieving of gear -like components with improved temperature uniformity.
Presentation also provides a review of basic principles and applications devoted to induction hardening small,medium and large size gears using tooth-by-tooth techniques and encircling method.
