ATTENTION!
Let the hot hubs cool down to ambient temperature, before inserting the buffer ring.
•
To facilitate mounting, the buffer ring
can be coated with a lubricant (for
ex. talcum for Perbunan Pb, or com-
mercial roller bearing grease for
polyurethane Vk).
•
Install the buffer ring on one of the
coupling halves.
•
Push the shaft ends with the
mounted coupling halves together.
(Fig. 5).
•
Align the coupling in accordance
with the instructions given in chapter
8 ‘Coupling Alignment’.
8 Coupling
Alignment
§
Danger of Injuries!
§
Disconnect the drive before carrying out any work on the
coupling.
§
Secure the drive against unintentional re-start and rotation!
§
Note:
§
Accurate alignment of the coupling prolongs the lifetime of the
elastic buffer ring.
§
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
exceeded 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 maximum permissible misalignments stated in tables 2 to 4 are guiding values. We
recommend utilizing these values up to 50 % only when aligning the coupling, so as to
have sufficient reserves for thermal growth, foundation settlings etc. during service.
In special applications with high demands on quiet running characteristics or higher
speeds, alignment accuracies of
≤
0,1 mm may be necessary for the three alignment
levels.
§
If the coupling is mounted in a closed housing/ guard, so that alignment at a later point of
time will no longer be possible, make sure that the geometry and the fitting accuracy of
the contact surfaces ensure true alignment of the shafts within the specified tolerances
during service.
