Abstract
A flexible coupling for drivingly connecting two rotatable shafts or the like, and for use in applications where torque is transmitted only in one direction of rotation or where the torque transmitted in one direction of rotation is significantly greater than the torque transmitted in the other direction of rotation, includes a flex member consisting of four elongated flex elements fixedly joined together in a unitary rectangular arrangement. The two elements positioned on opposite sides of the rectangular arrangement are of substantially rectangular cross-sectional shape along a major portion of element length, and the elements of one such pair are thicker than the elements of the other pair. The flex member is connected between the two rotatable shafts in a manner which causes the thicker elements to be in compression and the thinner elements to be in tension during torque transmission in the favored direction. The difference in element thickness provides a more stable flex member structure, reducing unwanted spurious deflections and thereby improving the capacity for useful deflections associated with driving and driven member misalignments. The coupling may include only a single flex member or may have a number of such members connected in series to increase its misalignment capabilities.
