Abstract

The laser hardening of gear is a new surface hardening technology. According to the characteristics of the broad-beam laser hardening, the techniques have been put forward to obtain the uniform hardened case alone the surface of gear. The question that temper of the first hardened flank has been improved evidently. The measurement results show that the deformation of laser-hardened gear is very small, which does not influence the grade of gear. The results of contact fatigue comparison tests show that the contact fatigue limit stress of laser hardened gear is a little less than that of carburized gear, with an amplitude lower than 9%. The spread of contact fatigue life of laser hardened gear is lower than that of carburized gear.
