Demounting the shrink disk
•
Remove the protective cover.
•
Remove any rust deposits from the shaft and the interior of the hollow shaft.
WARNING
Serious injury
Risk of injury through flying fragments of the tensioning bolts.
Do not unscrew the tensioning bolts one after the other, in order to avoid them to break off due to overload
or due to uncontrolled loosening of the shrink disk.
•
Undo all the tensioning bolts one after the other by approx. 1/4 turn.
The stored energy of the outer ring is slowly loosened during disassembly via the bolts to be loosened. For
this to be carried out correctly, the procedure described here must be carefully adhered to.
•
All the tensioning bolts should now be further undone by loosening one after the other by approx. 1 turn.
The outer ring should now release of its own accord from the inner ring. If this is not the case, the outer ring
can be detensioned with the forcing threads.
To this purpose screw some of the adjacent fastening bolts into the forcing threads. The now releasing
outer ring is braced against the remaining bolts. This operation must be carried out until the outer ring
completely releases of its own accord.
•
The shrink disk is to be secured against axial shifting.
•
Draw the stub shaft out of the hollow shaft.
•
Pull the shrink disk off the hollow shaft.
WARNING
Serious injury
Risk of injury through falling shrink disk or single parts thereof.
Make absolutely sure that the shrink disk cannot slip off the hollow shaft.
For transporting and lifting the shrink disk it may be required to use a suitable lifting device.
