Coupling arrangement for coupling a motor to a hoist machine

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.
