ABSTRACT:
In accordance with the teachings of the present invention, a flexible coupling assembly installed between a driving member and a driven machine or device. The flexible coupling assembly includes a one-way over-running clutch mechanism incorporated therein and transfers torque from the driving member to the driven device, while compensating for any angular and offset misalignment between two coupling members. The clutch mechanism provides driving torque in one rotational direction and over-running capability in the other, thereby accommodating large torque fluctuations from the driving member. This clutch mechanism is integrated within an intermediate housing assembly that is easily coupled between two jaw-type shaft couplings. Because the present invention eliminates the need for an intermediate shaft between the flexible coupling and a separate clutch mechanism, it further simplifies the installation of the assembly while reducing the overall space required.
