Hints and Instructions Regarding the Use in
Hazardous Areas
5.7 Breakdowns, Causes and Elimination
Continuation:
•
No original KTR parts (purchased parts) are used.
•
Old spiders/already worn out spiders or superposed spiders are used.
•
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.
breakdowns causes
danger hints for
hazardous areas
elimination
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
change of the
running noises
and/or occurring
vibrations
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
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
break of cam
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
