Investigation on Induction Hardening Treatment of Cylindrical Drive Gear Shaft

摘要

The feasibility of applying induction hardening treatment in the production of cylindrical drive gear shaft, which is made of medium carbon low alloy steel and used in heavy duty tandem bridge, is investigated. The approaches, inductor structure, parameters, deformation pattern and torsion strength of the induction hardening treated cylindrical drive gear shaft are analyzed and compared with the carburized parts. The results show that induction hardening can be applied in the strengthening of the cylindrical drive gear shaft and the torsion strength of the parts is higher than those using carburizing treatment, and satisfy loading design specifications. The deformation after quenching is within the required tolerance of the assembly.
