Axially spaced perpendicularly disposed rigidly slidable radial dual torque pin universal rotary shaft coupling

摘要

Large parallel and angular misalignment capabilities between coupled rotary shafts are provided in a torsionally rigid coupling by slidable and rotatable medial mounting of each of two radial, axially spaced, perpendicularly disposed torque pins through axially spaced radially perpendicular apertures through an axial connector and slidably trapping each end of each radial torque pin in an arcuate path between two apposed arms of one of two radially opposed forks projecting inwardly about either end of the axial connector from one of two yoked hubs. The perpendicular relation of the torque pins and slidable and rotatable medial mounting through the axial connector with ends trapped in opposed arcuate paths between radially opposed forks of each yoked hub allows displacement of the torque pins, with respect to the axial connector or the yoked hubs, about three mutually perpendicular axes thereby accommodating parallel and angular misalignment between coupled rotary shafts.
