Breakdowns, Causes and Elimination
Continuation:
• The coupling used/the coupling protection used is not suitable for the operation in hazardous areas and does
not correspond to EC Standard 94/9/EC, respectively.
• Maintenance intervals are not observed.

anger hints for
hazardous areas
Elimination
change of the running
noises
and/or occurring
vibrations
misalignment
increased temperature the
the spider surface; danger
of ignition by hot surfaces
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) checking of wear see under point Control
wear of spider, short-
term torque
transmission due to
metal contact
danger of ignition due to
sparking
1) put the unit out of operation
2) disassemble the coupling and remove rests
of the spider
3) check coupling parts and exchange
damaged coupling parts
4) insert spider, assemble coupling parts
5) check alignment, correct if necessary
loose screws for axial
securement of hubs
danger of ignition due to
hot surfaces and 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) checking of wear see under point Control
break of cam
wear of spider, torque
transmission due to
metal contact
danger of ignition due to
sparking
1) put the unit out of operation
2) change complete coupling
3) check alignment
break of the cams due
to high shock
energy/overload
danger of ignition due to
sparking
1) put the unit out of operation
2) change complete coupling
3) check alignment
4) find out the reason of overload
operating parameters
do not correspond to
the performance of the
coupling
danger of ignition due to
sparking
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
mistake in service of
the unit
danger of ignition due to
sparking
1) put the unit out of operation
2) change complete coupling
3) check alignment
4) instruct and train the service staff
