Hints and Instructions Regarding the Use in
Hazardous Areas
5.7 Breakdowns, Causes and Elimination
breakdowns causes
danger hints for
hazardous areas
elimination
change of the
running noises
and/or occurring
vibrations
loose screws for
axial securement of
hubs
danger of ignition due
to sparking
1) put the unit out of operation
2) check alignment of coupling
3) tighten the screws to secure the hubs
and secure against self-loosening
4) check coupling parts and exchange
damaged coupling parts
5) checking of wear see under point
Control
break of the
eleastomer
elements due to
high shock
energy/overload,
cams of coupling
slip
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) disassemble the coupling and remove
rests of the elastomer elements
3) check coupling parts and exchange
damaged coupling parts
4) insert elastomer elements, assemble
coupling parts
5) find out the reason of overload
operating
parameters do not
correspond to the
performance of the
coupling/
cams of coupling
slip
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) check the operating parameters and
select a larger coupling (consider
installation space)
3) assemble new coupling size
4) check alignment
shearing of
elastomer elements
mistake in service
of the unit/
cams of coupling
slip
danger of ignition due
to hot surfaces
1) put the unit out of operation
2) disassemble the coupling and remove
rests of the elastomer elements
3) check coupling parts and exchange
damaged coupling parts
4) insert elastomer elements, assemble
coupling parts
5) instruct and train the service staff
premature wear of
elastomer elements
misalignment
1) put the unit out of operation
2) eliminate the reason for the
misalignment (e. g. loose foundation
bolts, break of the engine fixing, heat
expansion of unit components, change
of the assembly dimension E of the
coupling)
3) check coupling parts and exchange
damaged coupling parts
4) checking of wear see under point
