Malfunctions / Breakdowns
Malfunction
Possible Causes
Danger Guidelines
for
Areas
Solutions
Premature wear
on the 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
Danger of ignition due to
formation of sparks on
metallic contact of the cams
1)
Set the system out of operation
2)
Dismantle the coupling and remove the
remainders of the elastomeric element
3)
Check the coupling parts and replace if damaged
4)
Insert a new elastomeric element, install coupling
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
see Table 9
Danger of ignition due to

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

3)
Check the coupling parts and replace if damaged
4)
Insert a new elastomeric element, install coupling
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)
