| Outline of Final Research Achievements |
A new joining process was proposed to manufacture shaft products efficiently. As the shaft having a serrated, grooved and stepped zones formed the disc with a hole, mechanical locks were created in the axial and rotational directions between two components. Experiments using a steel shaft and an aluminum disc offered the optimum design of the shaft and conditions for connecting the components stiffly in both directions. The prototype of the shaft was improved to shorten the joining length. The revised shaft showed higher disassembling force in the axial direction and higher torque in the rotational direction than the prototype in comparison under the same joining length.
