Hints and Instructions Regarding the Use in
Hazardous Areas
5.7 Breakdowns, Causes and Elimination
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
e. g. contact with
aggressive liquids/
oils, ozone-
influence, too
high/low ambient
temperatures etc.
effecting a physical
change of the spider
danger of ignition due
to sparking in case of
metallic contact of the
cams
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
6) make sure that further physical changes
of the spider are excluded
premature wear of
spider
ambient/contact
temperatures which
are too high for the
spider, max.
permissible
e. g. T4 =
- 30 °C/+ 90 °C
danger of ignition due
to sparking in case of
metallic contact of the
cams
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
6) check and regulate ambient/contact
temperature (eventually even
elimination by using other spider
materials)
premature wear of
spider (liquefaction
of material inside
the spider cam)
drive vibrations
danger of ignition due
to sparking in case of
metallic contact of the
cams
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
6) find out the reason for the vibrations
(eventually elimination by spider with
lower or higher shore hardness)
If you operate with a worn spider (see item 5.2) and the subsequent contact of metal parts a due
operation meeting the explosion protection requirements and acc. to Standard 94/9/EC is not
ensured.
