Title: Surface hardening treatment of cam shaft
Inventor: SHIBATA KIMIHIRO
IPC: B23K26/352
Filed: 1986-11-26
Abstract: PURPOSE:To permit quick hardening treatment of a cam face with a simplified device for the hardening treatment of the cam face by projecting a laser beam which is parallel with the axial direction of a cam shaft and broader than the cam face to the cam face which is chamfered at both ends. CONSTITUTION:Both ends of the cam 2 are chamfered to form chamfered parts 8. The chamfering angle theta is set within about 30-60 deg. and the width (d) in the axial direction within about 1mm. A laser absorbent is preliminarily coated over the entire surface of the chamfered cam face 3. The cam shaft 1 is then rotated around the axial center and the laser beam B1 outputted from a laser oscillator 9 is reflected by mirrors 10, 11 to form a band-shaped laser beam B2 which is projected to the cam face 3. The projection width l of the beam B2 is adjusted to the size slightly larger than the overall width D of the cam 2. The cam face 2 is successively remelted by the rotation of the cam shaft 1 by which the cam face is hardened. The overall width of the cam face 3 is thereby hardened to nearly the uniform depth without having troubles such as erosion and shoulder shear droop at both ends of the cam 2.
