Operating instructions 10/2017
9.3.1
Possible faults when selecting the coupling and/or coupling size
•
Important information for describing the drive and the environment are not communicated.
•
System power too high.
•
System speed too high or too low.
•
Starting frequency too high.
•
The ventilation of the coupling is inadequate.
•
Chemically aggressive environment not taken into consideration.
•
The ambient temperature is not permissible. (See also section 5.)
•
Machining of a finished bore with incorrect diameter and/or incorrect fit assignment (see section 6 and
orderreleated title page).
•
The transmission capacity of the shafthub connection is not appropriate to the operating conditions.
9.3.2
Possible faults when installing the coupling
•
Components with transport or other damage are being fitted.
•
When fitting coupling parts in a heated condition, already fitted NEUPEX flexible elements (12) are
being excessively heated.
•
The shaft diameter is beyond the specified tolerance range.
•
Coupling sides are being interchanged, i.e. their assignment to the specified drive direction is incorrect.
•
Specified axial fixtures are not fitted.
•
Specified tightening torques are not being adhered to.
•
Alignment / shaftmisalignment values do not match the operating instructions.
•
An incorrect operating fluid and/or an incorrect quantity of operating fluid is being put in.
•
The coupled machines are not correctly fastened to the foundation, and as a result shifting of the
machines e.g. through loosening of the foundationscrew connection is causing excessive
displacement of the coupling parts.
•
NEUPEX flexible elements (12) are being omitted or incorrectly positioned.
•
The coupling protection does not comply with the guidelines to be applied. It considerably restricts
ventilation of the coupling.
•
Operating conditions are being changed without authorisation.
•
Components are being fitted to the coupling which transmit excessive axial forces or bending moments
to the coupling.
•
Addon parts such as belt drives or brake disks are not designed in compliance with the
Directive 2014/34/EU and are an explosion hazard.
