Malfunctions / Breakdowns Type 494._ _ _._ (continued)
Result of
Malfunction
Possible Causes
Solutions
Premature wear
on the elastomeric
element
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
installation dimension “E”)
3)
Check the clutch for wear
4)
Insert a new elastomeric element
e.g. contact with
aggressive liquids / oils, ozone
influences, excessively high ambient
temperature etc., which lead to
physical changes in the elastomeric
element
1)
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
6)
Make sure that further physical changes to the elastomeric
element can be ruled out
The ambient or contact temperatures
permitted for the elastomeric element
are exceeded
1)
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
6)
Check the ambient or contact temperature and regulate them
(if necessary, use other elastomeric element materials)
Premature wear
on the elastomeric
element (material
liquidation inside the
elastomeric element
toothing)
Drive vibrations
1)
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.
6)
Find the cause of vibration (if necessary, use an elastomeric
element with a lower or higher shore hardness)
