Method and apparatus for effecting interference fit of two parts by accelerating one of the parts

摘要

Method and apparatus for effecting an interference fit of a first part and a second part, wherein a thrust force is applied to the second part in a direction toward the first part to thereby accelerate the second part for applying a kinetic energy to the second part to cause abutting contact of the second part with the first part for achieving the interference fit of the first and second parts, and wherein the initiation of acceleration of the second part by the thrust force is inhibited until the thrust force has been increased to a predetermined threshold, and is permitted when the thrust force has been increased to the predetermined threshold.
