Abstract

PURPOSE: To make free the selection of the material for the joint parts, and to make possible the metallic shaft and disk parts to be mutually strongly jointed, by inserting the third joint parts into the gap at the jointed portion of two joint parts, and by pressing this third joint parts so as to cause the plastic flow.
CONSTITUTION: The grooves 112, 122, are formed in the surface of the jointed portion between the first joint parts 110 of disk, etc., provided with a central hole and the second parts 120 of disk, shaft, etc., whose outer diameter is a little smaller than the diameter of above hole. The depth of above grooves 112, 122, is desirable to be about 0.2W0.6mm. Next, the third joint parts 130, which has a deformation resistance smaller than that of the material of the first and the second joint parts 110, 120, and has a specified mechanical strength, is inserted into the gap 140 between the joint parts 110, 120. After that, whole assembly is placed on the dies 40, and the third joint parts 130 is pressed by the pressing convex portion 32 of the dies 30, provided with the tip face 31 narrower than the breadth of the gap 140; hereby, the joint parts 130 is flown into the grooves 112, 122, due to the plastic deformation, and both of joint parts 110, 120, are jointed by the shearing force and the tightening force of the joint parts 130.
