During operation of the coupling, please pay attention to
different operating noise
vibrations occurring.
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
The below-mentioned failures can lead to a use of the
ROTEX
®
coupling other than intended. In addition to the
specifications given in these operating and assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
General failures with use other than intended:
Important data for the coupling selection were not forwarded.
The calculation of the shaft-hub-connection was disregarded.
Coupling components with damage occurred during transport are assembled.
If the heated coupling flanges are assembled, the permissible temperature is exceeded.
The fit of the components to be assembled is not coordinated with one another.
Tightening torques have been fallen below/exceeded.
Components are mixed up by mistake/assembled incorrectly.
A wrong or no spider is inserted in the coupling.
No original
KTR
components (purchased parts) are used.
Old/already worn out spiders or spiders stored for too long are used.
Maintenance intervals are not observed.
Breakdowns

Elimination
Different operating noise
and/or vibrations
occuring
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
Wear of spider, short-term torque
transmission due to metal contact
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
Screws for axial fastening of hubs
working loose
1) Set the unit out of operation
2) Inspect alignment of coupling
3) Tighten the screws to fasten the hubs and secure against
working loose
4) For inspection of wear see item inspection
