coupling other than intended. In addition to
the specifications given in these operating and assembly instructions please 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 not considered.
Coupling components with damage occurred during transport are assembled.
If the heated hubs are assembled, the permissible temperature is exceeded.
The clearance 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.
No original
KTR
components (purchased parts) are used.
Maintenance intervals are not observed.
Breakdowns
Causes
Elimination
Different operating noise
and/or vibrations
occurring
Screws working loose
1) Set the unit out of operation
2) Inspect tightening torque of screws.
3) Inspect torque setting.
4) If you cannot find out the cause of the failure, return
the coupling to KTR for inspection.
