Abstract
A threaded bush assembly for receiving and coupling a shaft to a rotatable hub includes a tubular sleeve member which is located within the rotatable hub and a tubular bush member adapted to be received in either end of the sleeve member. The bush member has a central bore in which the shaft is received and is axially moveable relative to the sleeve member by means of screw threaded members. The inner circumferential surface of the sleeve member and the outer circumferential surface of the bush member each have a helical thread formed thereon. The cross-section of both threads is defined by a pair of mutually opposed tapered surfaces. The two threads are screw threadedly engageable with one another, yet define a gap therebetween which enables relative axial movement of the two threads with respect to one another such that upon axial movement of the bush member relative to the sleeve member, one tapered surface of one thread wedges against the facing tapered surface of the other thread.
