ABSTRACT:
An electromagnetic brake is disclosed which comprises a brake wheel, a friction surface touching the brake wheel during braking and attached to an anchor plate moved by brake springs and an electromagnet which disengages the friction surface from contact with the brake wheel when a current is supplied to the magnet. To compensate for the wear of the friction surface, the brake has at least one retainer mounted on a bolt or shaft lying parallel to the axial direction of the brake. The retainer moves with the anchor plate towards the brake wheel and is provided with a directional element which limits the motion of the anchor plate away from the brake wheel. The brake is also provided with a wedge ring rotated by a spring which serves to move the electromagnet towards the brake wheel.
