Abstract
Serration joining, a joining method of a serrated rotor shaft and a holed disk, is developed to manufacture efficiently automobiles axle parts with high torsional strength. The rotor shaft, which is serrated by cold extrusion before hardening by heat treatment, is pushed into the hole of the soft disk at room temperature. This serrated shaft plastically indented the disk and consequently the shaft and the disk are joined. The teeth formed on the disk are strengthened by work-hardening and the torsional yielding strength of the joint is 1.5 times as high as that of a mechanical assembly.
