Patent ID: 7407040

Claim:
A coupling arrangement for coupling a motor to a hoist machine, the motor having a shaft extending in a direction normal to the motor face, the coupling arrangement comprising: a first drum flange comprising an outer body having a first end and a second end, an inner wall surface defining a cavity of substantially circular cross section, the cavity having a given diameter along a first length of the body, and of reducing diameter along a second length of the body, the flange adapted to receive at said first end a tapered bushing of increasing diameter and dimensioned such that, upon insertion of the bushing within the body a given length, the bushing frictionally engages with the inner wall surface of reducing diameter for retention therein; the bushing having a central cavity for receiving the shaft of the motor and means for securing onto the shaft; and wherein the first end of the drum mount flange is coupled directly to a portion of a brake drum within an interior portion of the hoist machine, wherein the motor face is coupled to an outer portion of the hoist machine, wherein the first end of said drum mount flange body includes through-holes alignable with corresponding holes in said brake drum, a pin having a corresponding pin bushing being positioned in each of said through-holes for connecting said drum mount flange to said hoist machine.
