摘要： A hollow shaft material is provided with, on an outer peripheral surface side thereof, for example, a movable induction heating coil wrapped therearound. While a high-frequency current with a predetermined frequency is caused to flow through the induction heating coil, the induction heating coil is axially moved to perform induction hardening of the hollow shaft material from the outer peripheral surface side. At this moment, the frequency of the high-frequency current caused to flow through the induction heating coil is set relatively low as to the small-diameter portions, which have a relatively small thickness, and the frequency of the high-frequency current caused to flow through the induction heating coil is set relatively high as to the large-diameter portion, which has a relatively small thickness.

摘要： An integral hollow type power transmission shaft is proposed which is superior in the balance between the static strength and the fatigue strength. The integral hollow type shaft is induction-hardened from the outer periphery to form a hardened layer, leaving an unhardened layer at spline portions, so that at the spline portions, the hardness on the inner surface will be lower than at other portions. This increases the toughness and compressive residual stress of the shaft at the spline portions, which tend to be starting points of fatigue cracks, thus improving the balance between the static strength and the fatigue strength.

摘要： An object of the present invention is to provide a technique for improving a strength, especially a fatigue strength of a power transmission shaft provided with a serrated portion for torque transmission such as a spline shaft. A power transmission shaft is serration-fitted to an inner joint member of respective constant velocity joints. A drive shaft is provided with a serrated portion as well as a smooth portion having a cylindrical outer circumferential surface. A cut-up portion is formed at the end portion of the serrated portion. When applying an induction hardening to the smooth portion and the serrated portion, a hardening ratio of the smooth portion is set at a different value from that of the serrated portion, and such that a fatigue strength of the smooth portion becomes equal to or greater than that of the serrated portion.
