An electromagnetic caliper type
brake belongs to the technical field of brakes and comprises a movable disc, a static disc, an
electromagnetic coil, a braking spring, a
brake caliper, a left friction plate, a right friction plate, a mounting seat and a guide rod. The
electromagnetic coil and the braking spring are respectively disposed in the static disc, the braking caliper is fixed with the static disc, the left friction plate is attached onto the inner side of the movable disc, the right friction plate is attached on the inner side of the
brake caliper, the mounting seat is used for being fixed with a traction
machine, and the guide rod is penetratingly arranged in a mounting hole of the brake caliper and fixed with the mounting seat. The electromagnetic caliper type brake is characterized in that a lining ring is disposed in the mounting hole of the braking caliper, a
steel ball retainer is sleeved on the guide rod, a
steel ball on the
steel ball retainer is respectively in rolling fit with an inner
peripheral surface of the lining ring and an outer
peripheral surface of the guide rod, so that the braking caliper can move in parallel relative to the guide rod, and the guide rod is provided with an anti-slipping mechanism which is used for preventing the steel ball
retainer from slipping off from the guide rod. The electromagnetic caliper type brake has the advantages that automatic adjustment and
equidistant division of clearances under optional states can be realized, safety of a
braking system is improved, and the electromagnetic caliper type brake is convenient in maintenance.
