Abstract: 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.

Abstract: An outer shaft is spline-fitted to an inner shaft and, after thus assembling the shafts, an adjustment screw is moved inwards in the radial direction while being fastened. An interval in the radial direction between a screw member and a receiving member of a diameter-expanding member is thereby expanded, thereby thrusting the inner shaft outward in the radial direction against the outer shaft. A thrusting force acting in the radial direction on the inner shaft against the outer shaft can be adjusted by controlling a fastening force of the adjustment screw. It is therefore possible to easily adjust a slide resistance between the two shafts and surely prevent a “backlash” between the two shafts.

Abstract: A method of fabricating a driveline assembly including the steps of inserting a first member within a second member, heating the first member to a temperature greater than that of the second member and inserting both members into a die. The inner surface of the die includes an interlocking torque transferring profile. Fluid pressure is applied to the inner diameter of the inner member to expand both members into the profile on the inner surface of the die. The inner and outer members are then removed from the die and cooled such that both members are at a common temperature. Because the inner member was at an elevated temperature, and thereby expanded a greater amount than the outer member, cooling of the members results in a clearance between the members that provides for relative axial movement between the inner and outer members.
