Alignment - Siemens Flender FLUDEX 4600 Series Operating Instructions Manual

If necessary, heating the brake disk and the N­EUPEX coupling hubs (to maximum + 150 °C) will facilitate
fitting. With temperatures over + 80 °C the flexible elements (12) must be removed from the coupling part 1
before heating. Before fitting coupling part 2 the part 3 must be fitted on the shaft.
Take precautions to avoid burns from hot parts.
The N­EUPEX add­on coupling must be fitted using the entire length of the bore or until it comes into
contact with the shaft shoulder. Axial securing is effected by means of the set screw or end plate.
Tightening the set screws to the tightening torque specified in item 6.1.4.
Failure to observe these instructions may result in breakage of the coupling.
Danger from flying fragments.
The coupling then becomes an explosion hazard.
Remount the removed flexible elements. It must be ensured that the flexible elements are absolutely of
identical size and have identical markings. The coupling parts must be only at a maximum temperature
of + 80 °C.
Move together the machines to be coupled.
Danger of squeezing.
Dimension "S" must be adhered to. The tightening torques of the bolted connections of part 2/3, part 10,
and part 32 are to be checked (for tightening torques and distance dimension "S", see item 6.6 and
section 1).
If the FLUDEX coupling is screwed to components which conduct axial forces or
bending moments into the coupling, Flender must be consulted.

Alignment

FLUDEX couplings in combination with the flexible
N­EUPEX add­on
deviations of the shaft ends to be connected up to the
values shown in item 6.5.
When aligning, the radial and angular misalignment of
the shaft ends must be kept as small as possible,
because, other conditions being equal, this increases
the service life of the flexible elements.
The alignment must be checked once more with the
foundation bolts of the motor and gear unit/driven
machine tightened.
Any shaft misalignment through heating during
operation must be taken into account as far as
possible.
