DISTURBANCES
CAUSES
INDICATIONS OF
RISKS FOR HAZARDOUS
AREAS
CLEARANCE
Changes of
running noises
Vibrations
Wear of gear ring
Short-term torque transfer
by metal contact
Ignition risk by sparking
• Stop the unit
• Dismount the coupling
• Remove the gear ring
• Check the parts of the coupling and exchange damaged
parts
• Renew the gear ring
• Check and, if necessary, correct the alignment
• Tighten the fixing screws with tightening torque and protect
it from self-loosening with Loctite
Break of
claw
Blockage and overload
rupture of claws by
operating errors
Ignition risk by sparking
due to metal contact of
the claws
• Stop the unit
• Dismount the coupling
• Check the shafts and feather keys for damages
• Check the drive unit for damages
• Mount the complete coupling
• Check the alignment
• Tighten the fixing screws with tightening torque and
protect it from self-loosening by Loctite
The parameters for the
determination of the
coupling do not correspond
to the actual operation
conditions. Dimensions of
coupling too small.
• Stop the unit
• Dismount the coupling
• Check the shafts and feather keys for damages
• Check the operating parameter and choose a harder gear
ring or bigger coupling
• Check the mounting space when deciding for a bigger
coupling
• Mount the complete coupling
• Check and correct, if necessary, alignment and dimension
E of the coupling
• Tighten the fixing screws with tightening torque and
protect it from self-loosening with Loctite
Increased wear of gear ring
Claws smash during torque
transfer
Premature wear
of gear ring
Error of alignment
Dimension E
was not kept
Ignition risk by high
temperatures at the
gear ring
• Stop the unit
• Check the mounting and remove errors of alignment
• Check the parts of the coupling and exchange damaged
parts
• Exchange the gear ring
• Check and correct, if necessary, alignment and dimension
E of the coupling
• Tighten the fixing screws with tightening torque and
protect it from self-loosening with Loctite
Torsional vibrations
destroy the charged teeth
inside
Ignition risk by sparking
during metal contact of the
claws
• Stop the unit
• Check the parts of the coupling and exchange damaged
parts
• Find out and remove cause of vibration
• Exchange the gear ring (eventually choose smaller or
higher shore hardness, please pay attention to the size of
the coupling)
• Check and correct, if necessary, alignment and dimension
E of the coupling
• Tighten the fixing screws with tightening torque and
protect it from self-loosening with Loctite
