Procedure for aligning the coupling:
Remove the protective cover
Check alignment of the coupling halves with one another
and compare with the maximum permissible values. Refer
to Table 8-1 and Table 8-2
Do not exceed the maximum permissible values for axial
offset (
Ka), radial offset (
Kr) and angular offset (
Kw)
Specifications for the respective coupling can be obtained
from the following sources:
- On the fan data sheet
- In the spare parts list
Loosen the fastening screws for motor and bearing
Perform fine adjustment and align the coupling
Where necessary, insert thin shims to compensate any
differences in height
Tighten the fastening screws with the tightening torque
prescribed in the instructions of the coupling
manufacturer; refer to the separate instructions for the
coupling
Mount the protective cover of the coupling
