A lightweight, flexible coupling is provided by the present invention for transmitting torque and accommodating axial and angular misalignment between drive and driven shafts. The coupling includes at least one reinforcing ring disposed between a pair of hubs or plates having projecting pins to which are secured elongated filaments that are coated or impregnated with a flexible matrix. The filaments are wrapped from the hub or plate on one side of the reinforcing rings(s), to and across the reinforcing rings(s) and then to the hub or plate on the opposite side of the reinforcing ring(s) following a geodesic path. Torque applied to the coupling is thus transmitted between the hubs or plates solely through the filaments.

Flexible coupling

A lightweight, flexible coupling is provided by the present invention for transmitting torque and accommodating axial and angular misalignment between drive and driven shafts. The coupling includes at least one reinforcing ring disposed between a pair of hubs or plates having anchoring means, wherein an elongated fiber strand coated or impregnated with a flexible matrix is wrapped from the hub or plate on one side of the reinforcing ring(s), to and across the reinforcing ring(s) and then to the hub or plate on the opposite side of the reinforcing ring(s) following a geodesic path. Torque applied to the coupling is thus transmitted between the hubs or plates solely through the fiber strands.
