ABSTRACT:
A flexible coupling for torque transmission having a plurality of helical beams extending between the coupling ends, the helical beams having beam cross-sectional dimensions selected to provide equal stresses in operation at the inner and outer diameters of the beams, irrespective of direction of rotation and being of a ratio of depth to thickness to provide for substantially simultaneous failure in the buckling and elastic modes when rotated in a direction opposite the direction of beam spiral, whereby the load capacity of the coupling is independent of the direction of coupling rotation.
