【Abstract】 Laser hardening is one new technique for surface hardening of spur gears.The three key techniques for laser surface hardening of gear have been proposed in this paper.With using these techniques,a uniform hardened case along the flank of gear can be obtained easily.The test results show that the deformation of laser-hardened gear is too small to influence the grade of gear.更多还原
