4.4.4 Adjusting the air gap
Fig. 10 Adjusting the air gap
1. Loosen the bolts (10).
2. Slightly turn the sleeve bolts (9) using an open end spanner.
- If the air gap is too large, screw into the stator (1.1).
- If the air gap is too small, screw them out of the stator (1.1).
- A 1/6 turn will change the air gap by approximately 0.15 mm.
3. Tighten the screws (10) (for torques, refer to table 16).
4. Check the air gap "s
L
" near the bolts (10) with a feeler gauge, ("s
LN
" 15).
5. Repeat the adjustment procedure if the deviation of "s
LN
" is too large.
WARNING
Danger: rotating parts!
Switch off the voltage. The drive system must be free of loads.
NOTICE
First correctly adjust the air gap with every 2nd bolt (10) / sleeve bolt (9)! The other three sleeve
bolts should be screwed into the stator so that they do not touch the flange or the bearing
shield. Then repeat the process with the other three bolts (10).
NOTICE
Only for brakes with manual release
❚ Also check dimension "s" and readjust, if necessary 30.
