Abstract

See full text

A cone piece is tightened into a compatibly shaped hole in the end of a shaft. As the cone piece is tightened, it forces the shaft to expand outwards. As the shaft expands, it creates or increases pressure against a hub, wheel, crank or other mating piece that is positioned on the shaft, locking it into place.
