<p>A composite shaft comprising at least two axial segments of dissimilar materials, the segments being held together by a central tie-bar, wherein a segment of material least subject to radial expansion is provided with a coaxial male member extending axially from its end, and the cooperating segment subject to greater radial expansion is provided with a female skirt shrunk onto the male member in the assembly of the shaft and also being provided with an annular upstand, at or towards its peripheral edge and directed towards the cooperating segment, the upstand being held by the compressive force of the tie-bar always in full annular contact with its cooperating segment. The male member is of smallest practicable diameter and the upstand is of largest practicable diameter.</p> |
