Material proper-
ties of elastic
buffers change.
The torque
transmission
capability is
adversely af-
fected.
-
Disconnect drive
-
Replace elastomer
-
Re-align coupling
-
Adjust ambient temperature
Contact

aggressive
products
Material proper-

fected.
-
Disconnect drive
-
Check coupling parts for damages
and replace parts, if necessary
-
Replace elastomer
-
Verify alignment of coupling
-
Prevent contact with aggressive
products
Torsional
vibrations
in the drive
line
Considerable
increase in
coupling tempera-
ture. Premature
wear of elastic
buffers. Increased
reaction forces act
on connected
machines.
-
Disconnect drive
-
Analyse and eliminate cause for
torsional vibrations
-
Check coupling parts for damages
and replace parts, if necessary
-
Replace elastomer and consult
RINGFEDER POWER
TRANSMISSION concerning even-
tual use of another Shore-hardness
-
Verify coupling alignment
Claw break-
age
Wear limit
of elas-
tomer
exceeded
===>
contact of
claws
Coupling is
destroyed.
Connected
machines can be
affected, too.
-
Disconnect drive
-
Replace coupling
-
Inspect the elastomer for wear at
shorter intervals
Overload
due to too
high torque
Coupling is
destroyed.
Connected
machines can be
affected, too.
-
Disconnect drive
-
Verify coupling design in coopera-
tion with RINGFEDER POWER
TRANSMISSION
-
Replace coupling
-
Install larger coupling, if necessary
