Abstract
A torque transmission comprising input and output shaft adapters. Pins disposed on an outer surface of the input shaft adapter. Each pin provides a curved pin portion oriented generally perpendicular to the input shaft adapter's longitudinal axis. The output shaft adapter provides a recess with a plurality of receptacles (or 'notches') formed in the recess's periphery, wherein the recess is shaped and sized such that when the input shaft adapter is received inside the recess, each pin is received into a corresponding notch. The torque transmission further comprises torsional bearings interposed between the pins and the notches, each torsional bearing providing a curved laminate portion such that the curved laminate portions contact the curved pin portions when the pins are received into their corresponding notches. The torsional bearings may further provide flat laminate portions that contact the notch when the pins are received into the notches.
