General failures with use other than intended:
•
Important data for the coupling selection are not forwarded.
•
The calculation of the shaft-hub-connection is 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.
•
Old/already worn out sleeves or sleeves stored for too long are used.
•
Maintenance intervals are not observed.
Breakdowns
Causes
Hazard notes for
potentially explosive
atmospheres
Elimination
Different operating
noise and/or
vibrations occuring
Micro friction by faulty
alignment on the
spline of the nylon
sleeve
Danger of ignition due to
hot surfaces
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 chapter 9.2
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 chapter 9.2
Breaking of the nylon
sleeve/spline
Breaking of the nylon
sleeve/spline due to
high shock
energy/overload
none
1) Set the unit out of operation
2) Disassemble the coupling and remove
remainders of the nylon sleeve
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert nylon sleeve, 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 nylon sleeve
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert nylon sleeve, assemble coupling
components
5) Instruct and train the service staff
Excessive wear on
the spline of sleeve
Vibrations of drive
Danger of ignition due to
hot surfaces
1) Set the unit out of operation
2) Disassemble the coupling and remove
remainders of the nylon sleeve
3) Inspect coupling components and replace
coupling components that have been
damaged
4) Insert nylon sleeve, assemble coupling
components
5) Inspect alignment, adjust if necessary
6) Find out the reason for vibrations
