Malfunctions / Breakdowns Type 494._ _ 4.2 / Size 5
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 "Z")
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
Unbalance
1)
Set the system out of operation
2)
Check the balance condition of the system components and
correct if necessary
3)
Check the coupling parts for wear
4)
Check the alignment and correct if necessary
Loose connection screws
1)
Set the system out of operation
2)
Check the coupling alignment
3)
Tighten the 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
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 /
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 clutch 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
