Patent ID: 8070375

Claim:
A universal shaft and coupling assembly for connection to a motor, comprising in an operative arrangement, an elongated shaft with a D-flat, said shaft enabled to receive different size couplings at the same or different axial locations along longitudinal points of said shaft, said couplings each comprising a unitary structure unit including a coupling device and a circular hub forming a hub-coupling unit, said hub-coupling unit being adapted to be installed or removed from operative contact with said shaft, said hub-coupling unit having on an outer terminal portion a component of an adjustable locking structure comprising locking tapered circular apertures which are enabled to be mated and lock with tapered pins in a universal mounting clamp, said mounting clamp enabled to be in locking contact with said D-flat of said shaft and said hub-coupling unit, a terminal portion of the hub-coupling unit nearest the D-flat are positioned said circular locking apertures which are circular positioned around a circular hub, said mounting clamp enabled to prevent both hub-coupling rotation and axial movement of said hub-coupling unit, said shaft having rounded configuration throughout its longitudinal portion except for said D-flat on its outer terminal section.
