Breakdowns
Causes
Elimination
Different operating noise
and/or vibrations occuring
Misalignment
1) Set the unit out of operation
2) Eliminate the reason for the misalignment (e. g. loose
foundation bolts, breaking of the engine mount, heat
expansion of unit components, modification of the
installation dimension E of the coupling)
3) Inspection of wear
Wear of elastomers
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
elastomer rings/pins
3) Inspect coupling components and replace coupling hubs
that are damaged
4) Generally assemble new elastomer rings with new pins
5) Assemble coupling components
6) Inspect alignment, adjust if necessary
Screws for axial fastening of
hubs working loose
1) Set the unit out of operation
2) Inspect alignment of coupling
3) Tighten the screws to fasten the hubs and secure against
working loose
4) Inspection of wear
Fracture of hub
Fracture of hub due to high
impact energy/overload
1) Set the unit out of operation
2) Replace complete coupling
3) Find out the reason for overload
4) Inspect alignment
Operating error of the unit
1) Set the unit out of operation
2) Replace complete coupling
3) Inspect alignment
4) Instruct and train the service staff
Early wear of elastomers
e. g. contact with aggressive
liquids/oils, ozone influence,
too high/low ambient
temperatures etc. causing a
physical modification of the
elastomer rings
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
elastomer rings/pins
3) Inspect coupling components and replace coupling hubs
that are damaged
4) Generally assemble new elastomer rings with new pins
5) Assemble coupling components
6) Inspect alignment, adjust if necessary
7) Make sure that further physical modifications of the pins are
excluded
ambient/contact
temperatures which are too
high for the elastomer ring,
max. permissible -
30 °C/+80 °C
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
elastomer rings/pins
3) Inspect coupling components and replace coupling hubs
that are damaged
4) Generally assemble new elastomer rings with new pins
5) Assemble coupling components
6) Inspect alignment, adjust if necessary
7) Inspect and adjust ambient/contact temperature
Early wear of pins
(hardening/embrittlement of
the pin elastomer)
Vibrations of drive
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
elastomer rings/pins
3) Find out the reason for vibrations
4) Inspect coupling components and replace coupling hubs
that are damaged
5) Generally assemble new elastomer rings with new pins
6) Assemble coupling components
7) Inspect alignment, adjust if necessary
!
If you operate with worn elastomer rings proper operation is not ensured.
