COUPLING AND METHOD OF COUPLING ROTATING ELEMENTS USING MAGNETICALLY TRIGGERED CONSTRICTING SPIRAL COIL

摘要

Apparatus and methods of coupling rotating elements (2, 3) employ a magnetically triggered constricting spiral coil (34) that exerts only radial forces to transmit torque through unrestrained unattached universally movable spheres (30). Methods of making spiral coils (34) are included.
