1) For operation above
80% of the declared maximum coupling speed it is recommended that the
coupling is dynamically balanced.
2) Installation should be initially aligned as accurately as
possible. In order to allow for deterioration in alignment over
time it is recommended that initial alignment should not exceed 25%
of the above noted data. The forces on the
driving and driven machinery should be calculated to ensure that these
do not exceed the manufacturers allowables.
3) Weights and inertias are calculated with mean bore for couplings
up to and including PM 600 and with maximum
bore for PM 900 and above.
4) Oversize shafts can be accommodated in large boss driving
flanges, manufactured to customer's requirements.
5) PM 0.4 - PM 3 driving flanges are available with solid bores
on request. |
