Magnetic repulsion coupling for transmission of a rotational movement from a driving member to a driven member

摘要

Coupling for transmission of a rotational movement from a driving member (10;110;210) to a driven member (20;120;220), comprising permanent magnets (13;23) which are respectively integral with the driving member (10;110;210) and the driven member (20;120;220), said permanent magnets (13;23) having a matching polarity (N-N;S-S) and lying in respective radial planes parallel to the axis of rotation and situated opposite each other so that each pair of facing magnets produces a corresponding magnetic repulsion force.
