Malfunctions / Breakdowns Type 494._ _ 4._ / Size 4
Malfunction
Possible Causes
Solutions
Changes in running
noise and / or
vibration occurrence
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 clutch 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 clutch and remove the remainders of the
elastomeric element
3)
Check the coupling parts and replace if damaged
4)
Insert elastomeric element, mount the clutch 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 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
Cam breakage
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 / overload / excessive shaft
misalignment
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
Clutch characteristic values are
exceeded due to incorrect operation
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
Premature wear on
the elastomeric
element
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 clutch installation
dimension "E")
3)
Check the coupling for wear
