SHAFT JOINT Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: coupling link is positioned in the space between the mutually facing coaxial shafts 1 and 2 to be joined. The coupling link is made up as two cylindric bars 3 and 4. The shaped ends of bars 3 and 4 are defined by arcs of circumferences of different radii. The centers of the circumference arcs of each bar is shifted one with respect to the other in the direction of the shaft rotation axis. Shaped ends of rods 3 and 4 as well as grooves of shafts 1 and 2 are defined by the circumference arcs in the plane perpendicular to the plane of the sketch, The diameter of the circumferences exceeds the bar length. The bars 3 and 4 are interconnected through rod 5 made up as a permanent magnet introduced into through opening of rod 3 and dummy opening of rod 4 made of a non-magnetic material. The axis of magnetic bar 5 is not in coincident with the centers of the circumference arcs of the shaped ends of bars 3 and 4. EFFECT: enhanced reliability. 2 dwg
