Abstract:
In combination a motor having a selectively rotatable axially extending motor shaft, a rotatable driven shaft and a coupling assembly for connecting said driven shaft in an axially aligned orientation to said motor shaft for rotation therewith,the coupling assembly including, a coupling jacket extending axially from a forward end proximate to said motor to a rearward end distal therefrom, the jacket defining an axially located central bore, a first end of the central bore extending into the forward end of the coupling jacket and being sized to at least partially receive therein an endmost portion of the motor shaft, the second other end of the central bore extending into the rearward end of the coupling jacket and being sized to at least partially receive therein an endmost portion of the driven shaft, an internally threaded bore being spaced radially outwardly from said axis and extending in the axial direction into the rearward end of the jacket, a lifting ring defining an open interior sized for circumferential placement about the driven shaft and being secured substantially against axially sliding movement relative thereto, the lifting ring including an aperture open in the axial direction, the aperture being located for positioning in substantial axial alignment with the internally threaded bore upon coupling of the lifting ring to the driven shaft, and a threaded connector having a threaded end with a complementary thread configuration to said internally threaded bore, said connector being insertable axially through said aperture with said threaded end in threaded engagement with said threaded bore, whereby the turning of the threaded connector moves the lifting ring and driven shaft in the axial direction relative to the coupling jacket and motor shaft.
