US Classification:

266239, 266235, 285 40

Abstract:

A molten metal pump shaft coupling system for use in the coupling or connection of elongated shafts to other components and equipment, and for the disconnection thereof. A coupling with internal discontinuous threads may be coupled with an externally threaded shaft, with either continuous or discontinuous threads. Aspects of the invention include multiple external threads which may be pitched to accomplish a quicker and more efficient disconnect system. Furthermore, a shaft removal system is provided which provides two points of contact to assist in rotating a broken shaft end out of a coupling.
