ABSTRACT:
A torque and air gap adjustment mechanism is provided for a spring engaged electromagnetic brake or clutch, and consists of a plurality of hubs threaded to one another and to the brake casing for axial movement with respect thereto and with respect to each other. A plurality of detents are disposed within the hub positioned in cylindrical holes with springs forcing them away from each other and out of the holes. These detents are retained in the holes at one end by a hub provided for the torque adjustment and at the other end by the brake plate. In both the hub and the brake plate there are indentations to retain the detents. These indentations have differing angles as do the engaging surfaces of the detents to permit torque adjustment independent of air gap adjustment upon rotation of the torque adjusting hub.
