10. Disassembling the brake
Danger to life and limb!
When disassembling the brake, it is essential to ensure that the entire drive
train is secured against inadvertent activation. Rotating components can
cause severe injuries. Therefore, rotating components (e.g. brake discs) must
be secured against accidental contact.
Attention - SIZE 018 !!
Do not remove the cables between the brake and the electronics as long as the
brake is energized, this will destroy the magnet! (see figure 8.3).
Attention!
Take care, that the electric supply cable is currentless.
Secure the brake for disassembly.
Remove the screws used to hold the brake in place. The brake can now be removed from the
mounting surface.
11. Maintenance
11.1 General maintenance
Maintenance must be performed on the brake at intervals of 4 weeks up to once a year, depend-
ing upon the operating load.
Perform the following checks during every maintenance operation:
•
Check brake pads for wear.
•
Check the air gap between the brake pad and the brake disk.
•
Check the bolt connection between the brake pad and the machine component as well as the
bolt connections for the retaining plates for tightness.
•
Check the electric supply cables (sight check).
11.2 Brake pad adjustment, permissable brake pad wear and brake pad replacement
Danger to life and limb!
Brake pads may be replaced only when the equipment system and/or the work-
ing machine is at a complete standstill!
Attention!
Brake pads must not be worn to a residual thickness (mounting plate thickness
plus remaining pad material). Brake pads must always be replaced in pairs.
Only original RINGSPANN brake pads may be used
Brake pad wear adjustment:
To counter brake pad wear you can adjust the distance between brake pad and brake disc with
set screws Pos. 41 and Pos. 17 (see Fig. 8.1 or 8.2). The gap between brake disc and brake pad
on each side should be 0,3 mm. The maximum allowable distance between brake disk and brake
Note:
If the brake is closed, there should
always be an air gap at this point. If
the air gap is smaller than 2mm, the
wear must be adjusted.
