Abstract: A coupling arrangement for coupling a traction sheave on a motor shaft includes a taper lock bushing and a traction sheave having a tapered bore adapted to receive the taper lock bushing. The taper lock bushing is sized to slidingly engage with the motor shaft and to fit into the tapered bore of the traction sheave. The taper lock bushing is fastened onto the traction sheave via threaded fasteners to result in a compression fit between the taper lock bushing and the motor shaft.

Abstract: There is disclosed a coupling arrangement for coupling a motor to a hoist machine. The coupling arrangement comprises a first drum flange comprising an outer body having a first end and a second end, and an inner wall surface defining a cavity of substantially circular cross section. The cavity has a given diameter along a first length of the body, and of reducing diameter along a second length of the body. The flange is adapted to receive at the 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 has a central cavity for receiving the shaft of the motor and capable of securing onto the shaft.

Abstract: A coupling arrangement for coupling a motor to a hoist machine comprises a first drum flange having an inner surface and an outer surface opposite the inner surface for coupling to a hoist machine to reduce vibrations. The drum flange has a central cavity for receiving a motor shaft. A second flange member has a bushing sized to the motor shaft, the second flange member having an inner surface and an outer surface opposite the inner surface for coupling to the motor. A coupling plate is positioned between the first and second flange members, wherein each of the first and second flange members has pins protruding from the respective inner surfaces and wherein the coupling plate has hole portions radially positioned and in alignment with the respective pins to receive the pins for securing thereto. The first flange member further includes hole portions, each for accommodating a connecting rod to securely fasten at the outer surface to a hoist machine.

Abstract: A bracket assembly and method for coupling a motor to a hoist machine comprising an adapter plate for coupling to a motor face and sized to cover the face of the motor and accommodate an existing motor register on the hoist machine, a drum flange member coupled to the hoist machine to reduce vibrations, the drum flange member having a central cavity for receiving the motor shaft, a second flange member having a bushing sized to the motor shaft, and a coupling plate positioned between the first and second flange members, the coupling plate made of a resilient material such as a plastic. Each of the first and second flange members and coupling plates have hole portions radially positioned and in alignment with one another, the drum flange having holes formed therein for accommodating a connecting rod such as a bolt to securely fasten the drum flange to the drum brake of the hoist machine.
