Possible Causes
Solutions
Changes in
running noise
and / or
vibration
occurrence
Incorrect alignment
1)
Set the system out of operation
2)
Find / resolve the cause of incorrect alignment
(e. g. loose foundation screws, motor securement breakage, heat
expansion of system components, changes in the coupling
distance dimension “E”)
3)
Check the clutch for wear
Wear on the elastomeric element,
temporary torque transmission due to
metal contact

Set the system out of operation
2)
Dismantle the clutch and remove the remainders of the
elastomeric element
3)
Check the clutch parts and replace if damaged
4)
Insert a new elastomeric element, install clutch components
5)
Check the alignment and correct if necessary.
Tensioning and clamping screws or
locking set screw for axial hub
securement or
connection screws are loose
1)
Set the system out of operation
2)
