Maintenance methods for electromagnetic brakes

In order to ensure the uninterrupted operation of the electromagnetic brake, it is necessary to regularly maintain and maintain it:

1. Frequently add lubricant to the movable part of the electromagnetic brake.

2. Regularly check the length of the armature stroke. Because during the operation of the brake, the travel length of the armature will increase due to wear on the moving surface. When the length of the armature stroke cannot reach the normal value, adjustments must be made to restore the minimum clearance between the braking surface and the rotary table. If the stroke length of the armature increases above the normal value, it may greatly reduce the suction force.

3. If a worn brake surface is replaced, the minimum clearance between the brake surface and the rotary table should be adjusted appropriately.

4. Regularly check the tightness of the bolts, especially tightening the bolts of the electromagnet, the bolts of the electromagnet and the shell, the bolts of the magnetic yoke, the bolts of the electromagnet coil, and the wiring bolts.

5. Regularly inspect the mechanical wear of movable components and remove dust, burrs, and dirt from the surface of electromagnetic components

The brake for cranes consists of brake pads, brake arms, brake wheels, and brake release devices. The brake wheel is often installed as a half body of the coupling on the rotating shaft of the mechanism. The symmetrically arranged brake arm is hinged with the fixed part of the frame, and the two brake pads with friction materials on the inner side are movable and hinged on the two brake arms. Under the action of the brake force on the brake release device, the paired brake pads compress the brake wheel radially and generate braking torque.
