Shaft-disc assembly

摘要

A disc is centered and secured on a shaft by means of flexible webs which extend parallel to the shaft and lie against the inner surface of a central aperture in the disc, and by radially extending tongues fixed to the shaft and entering into corresponding radial slots in the disc. As the assembly rotates, the webs are urged outwards by centrifugal force, to apply a radial compression force to the material of the disc.
