hazardous areas
Elimination
Early wear of spider
or reverse backlash
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
Excessively high/low
ambient/contact
temperatures 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.
