10. Operational disturbances

The possible operational disturbances are listed in the following table. In order to remedy them,

first bring the unit to a standstill

and then follow the further instructions in the column “Rem-

edy”. This table only provides a starting point for the search for the cause. All neighbouring com-
ponents should also be subjected to an examination.

Disturbances

Causes

Remedy

Changes in

sounds or

vibrations

Alignment error

1)  Eliminate the cause of the alignment error
2)  Carry out wear inspection
3)  Re-align the coupling

Lack of lubricant

1)  Carry out wear inspection
2)  Replace lubricant
3)  Check seals and replace if necessary

Excessive gearing

wear

Vibrations in the

drivetrain

1)  Disassemble coupling
2)  Replace damaged parts
3)  Find and eliminate cause for the vibrations
4)  Align coupling

Misalignment is

outside the

permissible range

1)  Disassemble coupling and examine
2)  Replace worn parts
3)  Check alignment and correct if necessary

Lack of lubricant

4)  Carry out wear inspection
5)  Replace lubricant
6)  Check seals and replace if necessary

Lubricant leaking

O-rings

worn

1)  Carry out wear inspection
2)  Clean coupling
3)  Replace O-rings
4)  Fill with lubricant

O-ring porous

due to false

storage or

damaged during

assembly

1)  Carry out wear inspection
2)  Clean coupling
3)  Optimise storage and eliminate the reason for

assembly errors

4) Replace O-rings
5) Fill with lubricant

O-rings damaged

due to contact

with aggressive

media, ozone or

hot surfaces

1)  Carry out wear inspection
2)  Clean coupling
3)  Eliminate negative influences
4)  Replace O-rings
5)  Fill with lubricant

Gearing or cou-

pling half breaks

Break due to

overload

1)  Disassemble coupling
2)  Replace damaged parts
3)  Eliminate cause for the overload
4)  Align coupling

The coupling se-

lected was too

weak

1)  Disassemble coupling
2)  Check the design of the coupling
3)  Install, align and lubricate larger coupling
