Brake
Maintenance
Without any malfunctions occurring, the running operation does not require
any maintenance except for a visual inspection of the brake disc lining, visual
inspection of the pressure plates, and verifying the size of the air gap. See
Figure 11-1. The air gap increases as the lining on the rotor wears. When the
maximum air gap is reached, an adjustment of the air gap is required for the
safe operation of the brake. The functional capability and safety function of the
brake will be compromised as additional wear occurs and must be replaced.
Inspections must be veried in accordance with the following schedule.
Inspection intervals:
Holding brake: At least every six months
Use shorter intervals in case of frequent emergency stops
1. Remove cover.
2. Slide the rubber seal to the side to expose the stationary disc and brass shim.
3. Visually inspect the brake disc for damage.
4. Visually inspect the pressure plates for discoloration.
5. Measure the air gap with a feeler gauge at
three dierent positions around
the brake
between the stationary disc and the coil. [See the next page for
the appropriate measurement or conrm current information with SEW
Eurodrive by calling 1-888-SEW-3876 and reference your serial number.]
