7 Coupling
Alignment
§
Danger of injuries!
§
Disconnect the drive before carrying out any work on the
coupling.
§
Secure the drive against unintentional re-start and rotating!
§
Note:
§
Accurate alignment of the coupling prolongs the lifetime of the disk
packs and reduces the risks when operating the coupling.
§
It is of utmost importance to observe the recommended alignment
values. Exceeding the permissible misalignment values results in
coupling damages and failures!
- When aligning the cold equipment take into account the expected thermal growth of the
components, so that the permissible misalignment values for the coupling are not ex-
ceeded in operation.
- Be aware that the coupling under misalignment imposes restoring forces on the adjacent
shafts and bearings. Take into account that the larger the misalignment, the greater the
restoring forces will be.
-
The total angular misalignment, combined of radial and angular displacement, for
each disk pack must never exceed the following values during operation:
