Heating up the coupling parts (to max. +150
°
C) may facilitate
pulling on the coupling parts. If temperatures 80
°
C,
the flexible coupling blocks must be removed from the coupling
parts before the heating process.
Protect against burns from contact with hot compo-
nents!
If the coupling blocks have been removed, they shall be re--in-
stalled after the coupling parts have been pulled on. Make sure
the heated coupling parts have cooled down to under 80
_
C be-
fore doing so. All coupling blocks used must be of identical size
and marking.
Push the machines to be coupled together.
Take appropriate precautions to prevent injury by
crushing.
Make sure to observe dimension S
1
. On types A and ADS, the
connection between parts 2 and 3 shall be re--established be-
fore aligning the coupling, and the tightening torque of the scre-
wed connection between parts 2 and 3 shall be checked (for
tightening torques and clearance S
1
please refer to point 6.6).
Aligning the coupling
(Also refer to section 5.3.2).
The couplings will only tolerate misalignment of the shaft ends
to be coupled to a certain extent.
When aligning the coupling, the radial and angular misalign-
ment of the shaft ends should therefore be minimized. With
identical operating conditions, the useful life of the flexible cou-
pling blocks will be increased as a result.
Coupling alignment shall be effected in two planes which are
normal to each other. Use a straight--edge (radial misalign-
ment) and feeler gauge (angular misalignment) as shown be-
low to verify.
Feeler gauge
Straight edge
Using a dial micrometer will make for increased measuring ac-
curacy.
To allow one shaft end to rotate freely, the driving section can
be separated on types A and ADS by loosening the screwed
connection between parts 2 and 3 and pulling part 3 out of the
recesses in part 1.
After
the
connection
has
been
re--established, check
the tightening
torque of the bolts.
