Abstract

A shaft structure comprising a shaft and a hollow spherical shell having diametrically aligned holes which are of a diameter smaller than the outer diameter of the shaft. The shell is secured to the shaft at the aligned holes by radially deforming the shaft. The method for manufacturing the shaft structure includes steps of forming the shell from a tubular blank by swaging the blank so that the opposite ends of the blank bite into the shaft to secure it firmly to the shaft.
