Trouble
Cause
Risk Warning
Correction
Contact with
aggressive
products
Material properties
of elastic buffers
change. The torque
transmission
capability is
adversely affected.
-
Disconnect drive
-
Check coupling parts for damages
and replace parts, if necessary
-
Replace elastomer
-
Verify alignment of coupling
-
Prevent contact with aggressive
products
Torsional
vibra
tions in the
drive line
Considerable
increase in cou-
pling temperature.
Premature wear of
elastic buffers.
Increased reaction
forces act on
connected ma-
chines.
-
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
Wear limit
of elas-
tomer
exceeded
===>
contact of
claws
Coupling is
destroyed. Con-
nected machines
can be affected,
too.
-
Disconnect drive
-
Replace coupling
-
Inspect the elastomer for wear at
shorter intervals
Claw
breakage
Overload
due to too
high torque
Coupling is
destroyed. Con-
nected machines
can be affected,
too.
-
Disconnect drive
-
Verify coupling design in coopera-
tion with
RINGFEDER POWER
TRANSMISSION
-
Replace coupling
-
Install larger coupling, if necessary
