Breakdowns
Causes
Elimination
Breaking of cams
Wear of spider, torque
transmission due to metal contact
1) Set the unit out of operation
2) Replace complete coupling
3) Inspect alignment
Breaking of the cams due to high
impact energy/overload
1) Set the unit out of operation
2) Replace complete coupling
3) Inspect alignment
4) Find out the reason for overload
Operating parameters do not
meet with the performance of the
coupling
1) Set the unit out of operation
2) Review the operating parameters and select a bigger
coupling (consider mounting space)
3) Assemble new coupling size
4) Inspect alignment
Operating error of the unit
1) Set the unit out of operation
2) Replace complete coupling
3) Inspect alignment
4) Instruct and train the service staff
Early wear of spider
Misalignment
1) Set the unit out of operation
2) Eliminate the reason for the misalignment (e. g. loose
foundation bolts, breaking of the engine mount, heat
expansion of unit components, modification of the
installation dimension E of the coupling)
3) For inspection of wear see item inspection
e. g. contact with aggressive
liquids/oils, ozone influence, too
high/low ambient temperatures
etc. causing physical modification
of the spider
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
spider
3) Inspect coupling components and replace coupling
components that have been damaged
4) Insert spider, assemble coupling components
5) Inspect alignment, adjust if necessary
6) Make sure that further physical modifications of the spider
are excluded
Ambient/contact temperatures
which are too high for the spider,
max. permissible
e. g. with T-PUR
®
T4 = - 50 °C/
+ 120 °C
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
spider
3) Inspect coupling components and replace coupling
components that have been damaged
4) Insert spider, assemble coupling components
5) Inspect alignment, adjust if necessary
6) Inspect and adjust ambient/contact temperature (possibly
corrective by using other spider materials)
Early wear of spider
(liquefaction of material
inside the spider cam)
Vibrations of drive
1) Set the unit out of operation
2) Disassemble the coupling and remove remainders of the
spider
3) Inspect coupling components and replace coupling
components that have been damaged
4) Insert spider, assemble coupling components
5) Inspect alignment, adjust if necessary
6) Find out the reason for the vibrations (possibly corrective
by spider with lower or higher Shore hardness)
In respect of environmental protection we would ask you to dispose of the packaging or products on termination of
their service life in accordance with the legal regulations and standards that apply, respectively.
Metal
Any metal components have to be cleaned and disposed of by scrap metal.
Nylon materials
Nylon materials have to be collected and disposed of by a waste disposal company.
