Malfunctions / Breakdowns Type 484._ _5._
Malfunction
Possible Causes
Solutions
Changes in running noise
and / or vibration
occurrence
Type 484.
Incorrect alignment
1)
Set the system out of operation
2)
Find / resolve the cause of incorrect alignment
(e.g. loose foundation screw, broken motor attachment,
warmth expansion of system components, changes in
coupling installation dimension "E")
3)
Check the coupling for wear
Worn elastomeric element, short-term
torque transmission via metal contact
1)
Set the system out of operation
2)
Dismantle the coupling and remove the remainders of the
elastomeric element
3)
Check the coupling parts and replace if damaged
4)
Insert new elastomeric element, mount the coupling parts
5)
Check the alignment and correct if necessary
Tensioning and clamping screws or locking
set screw for axial hub securement are
loose
1)
Set the system out of operation
2)
Check the coupling alignment
3)
Tighten the tensioning and clamping screws for axial hub
securement as well as connection screws to the required
torque or tighten the locking set screw and secure it
against self-loosening using sealing lacquer
4)
Check the coupling for wear
Loose connection screws
Cam breakage
Type 484.
Worn elastomeric element, torque
transmission via metal contact
1)
Set the system out of operation
2)
Replace the entire coupling
3)
Check the alignment
Cam breakage due to high impact energy /
overloading
1)
Set the system out of operation
2)
Replace the entire coupling
3)
Check the alignment
4)
Find the cause of overload
Operating parameters are not appropriate
for the coupling performance
1)
Set the system out of operation
2)
Check the operating parameters and select a suitable
coupling (observe installation space)
3)
Install a new coupling
4)
Check the alignment
Operating errors on the system unit by
exceeding coupling characteristic data
1)
Set the system out of operation
2)
Check the coupling dimensioning
3)
Replace the entire coupling
4)
Check the alignment
5)
Train and advise operating personnel
