Caliper disk brake for steel mill cranes

Abstract

A caliper disk brake includes a brake disk having at least one set of brake pads disposed on opposite sides thereof and connected to a pair of caliper arms. The caliper arm are interconnected with a magnetic actuator consisting of an armature slidingly received by a magnet body. A spring interposed between the armature and magnet body actuates the brake, while an electromagnetic coil releases it. A sealed cavity is provided between the armature and magnet body with a metered and valved vent in communication with the cavity to allow for controlled brake application and instantaneous release. A wear adjustment bolt received a trunion connected to one of the caliper arms and has an end thereof received within a bore of the magnet body maintaining the spring. Coaxially aligned with the wear adjustment bolt a torque adjustment bolt which secures a second trunion receiving the other caliper arm. The torque adjustment bolt communicates with the spring and, in combination with adjustment washers, allows for the presetting of a characteristic brake torque and a visual indication thereof. The magnetic actuator of the caliper disk brake assembly is mounted by bolts received within bushings which may consist of either a steel sleeve received within an elastomeric sleeve, or a steel sleeve received within a bronze sleeve.
