ABSTRACT:
The shaft coupling has two elastic threaded cylindrical parts on both sides. The threaded cylindrical parts have tapered screws on their outer surface. Tightening nuts are fitted to the tapered screws. Inserting shafts into the threaded cylindrical parts, an operator rotates the nuts to tighten the shafts. The threaded cylindrical parts are elastically bent inward and pressed on the shafts by rotationally-symmetric forces. The tapered screws with wide screw edge angle or with saw-shaped section are preferable to heighten the transmission performance of torques.
