Patent ID: 7097564

Claim:
A flexible coupling for flexibly joining two shafts, the flexible coupling comprising: a unitary solid cylindrical body having a first end, a second end, and therebetween having one or more longitudinally spaced circular disks spaced by asymmetric slot pairs; a radially offset beam, having a minimum beam thickness (T 1 ) and a longitudinal beam length (L 1 ), formed between a first slot and a second slot of each asymmetric slot pair, such that the radially offset beam is parallel to a diameter of the cylindrical body and is offset from the parallel diameter by a radial beam offset distance (R 1 ); each beam being rotationally offset from longitudinally adjacent beams; and means at the first end for coaxially connecting the first end to a first one of the two shafts, and means at the second end for coaxially connecting the second end to a second one of the two shafts.
