Table 5
Operating faults and their possible causes:
Trouble
Cause
Risk Warning
Correction
Irregular
running
noises/
vibrations
Alignment fault Considerable
increase in
coupling tempera-
ture. Premature
wear of elastic
buffers. Increased
reaction forces act
on connected
machines.
-
Disconnect drive
-
Remove cause for alignment fault
-
Re-align coupling
-
Inspect elastomer for wear
Elastomer
worn out
Coupling claws
strike against
each other. Spark
formation, claw
fracture, in-
creased reaction
forces.
-
Disconnect drive
-
Check coupling components for
damages and replace parts, if nec-
essary
-
Replace elastomer
Unbalance
Considerable
increase in
coupling tempera-
ture. Premature
wear of elastic
buffers. Increased
reaction forces act
on connected
machines
-
Disconnect drive
-
Verify balance state of plant compo-
nents and correct it, if necessary
-
Inspect elastomer for wear
Loose
screw
connec-
tions
Flying off parts
can cause serious
injuries and
considerable
damages.
-
Disconnect drive
-
Check coupling parts for damages,
replace parts, if necessary
-
Verify alignment of coupling
-
Tighten screws to the specified
tightening torque and secure them
against working loose, if necessary,
-
Inspect elastomer for wear
Premature
wear of
elastomer
Alignment fault Considerable
increase in
coupling tempera-
ture. Increased
reaction forces act
on connected
machines.
-
Disconnect drive
-
Remove cause for alignment fault
-
Re-align coupling
-
Inspect elastomer for wear
