Abstract
A molten metal rotor receives and retains an end of a molten metal rotor shaft. The rotor shaft has one or more projections at the end received in the rotor. The rotor has an inner cavity, a top surface with an opening leading to the inner cavity, and at least one abutment. The opening includes one or more portions for allowing each projection to pass through the opening and into the inner cavity. The rotor and/or shaft are then rotated so at least one of the outwardly-extending projections is under the top surface of the rotor and is against an abutment. A molten metal pump, rotary degasser scrap melter or other device used in molten metal may utilize a rotor/shaft combination as disclosed herein.
Claims21
A device comprising a rotor shaft, wherein the rotor shaft has a first end configured to be received in a coupling and a second end configured to be connected to a rotor, the second end having at least one outwardly-extending projection that is received and retained in a rotor cavity in order to connect the second end to the rotor;
- and wherein the rotor shaft has an outer surface and the at least one outwardly-extending projection extends outward at least ½″ from the outer surface.
