Malfunctions / Breakdowns Type 494._ _ 4._ / Size 4 (continued)
Malfunction
Possible Causes
Solutions
Premature wear on
the elastomeric
element
e.g. contact with aggressive fluids / oils,
ozone influence,
too high ambient temperatures, etc,
which cause 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 coupling parts and replace if damaged
4)
Insert elastomeric element, mount the clutch parts
5)
Check the alignment and correct if necessary
6)
Make sure that further physical changes in the elastomeric
element can be excluded
The ambient or contact temperatures
permitted for the elastomeric element
are exceeded, see Table 4
1)
Set the system out of operation
2)
Dismantle the clutch and remove the remainders of the
elastomeric element
3)
Check the coupling parts and replace if damaged
4)
Insert elastomeric element, mount the clutch parts
5)
Check the alignment and correct if necessary
6)
Check the ambient or contact temperature and regulate them
(possibly using other elastomeric element materials)
Premature wear on
the elastomeric
element (material
liquefaction in the
elastomeric element
tooth interior)
Drive vibrations
1)
Set the system out of operation
2)
Dismantle the clutch and remove the remainders of the
elastomeric element
3)
Check the coupling parts and replace if damaged
4)
Insert elastomeric element, mount the clutch parts
5)
Check the alignment and correct if necessary
6)
Determine the cause of vibration (maybe the problem can be
resolved by using an elastomeric element with lower or higher
shore hardness)
