The below-mentioned failures can result in a use of the
BoWex
®
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 hub is 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.
Old/already worn out flanges or flanges stored for too long are used.
Maintenance intervals are not observed.
Breakdowns
Causes
Elimination
Different operating noise
and/or vibrations occuring
Micro friction by faulty
alignment on the spline of the
flange
1) Set the unit out of operation
2) Eliminate the reason for the misalignment (e. g.
loose foundation bolts, breaking of the engine
mount, thermal expansion of unit components,
modification of the installation dimension l
3
and
l
7
of the coupling)
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
Fracture of flange/
spline
Fracture of flange/
spline caused by high
dynamic energy/overload
1) Set the unit out of operation
2) Disassemble the coupling and remove
remainders of the flange
3) Inspect coupling components and replace
coupling components that are damaged
4) Insert flange, assemble coupling components
5) 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) Disassemble the coupling and remove
remainders of the flange
3) Inspect coupling components and replace
coupling components that are damaged
4) Insert flange, assemble coupling components
5) Instruct and train the service staff
