INERTIALES PRESSVERBINDUNGSVERFAHREN

摘要

In an inertia-press-fit method in which a kinetic energy is applied to at least one of two members in a direction which causes the two members to approach each other, and the two members are press-fitted with each other, an end surface 80 of the first member 10 and a bottom surface 82 of the second member 12 are caused, for stabilizing a relative position of the two members at a time when the press-fitting ends, to butt each other to define the relative position of the two members 10, 12 at the time when the press-fitting ends and, immediately after the butting, at least one of the two members 10, 12 is caused to plastically deform and thereby absorb a remaining kinetic energy of the one of the two members. Thus, the relative position of the two members 10, 12 when the press-fitting ends is stabilized. In the case where respective plastic-deformation capabilities of the two members 10, 12 are great, a maximal value occurs to a graph whose axis of abscissa represents kinetic energy and whose axis of ordinate represents amount of deviation of relative position of the two members. If the respective plastic-deformation capabilities of the two members 10, 12 are so chosen as to decrease the maximal value, then the amount of deviation of the relative position is decreased even though the accuracy of control of the applied amount of kinetic energy may be low.
