Start­up and operation
Bolt­tightening torques for the coupling and tightening torques for the foundation
bolts of the coupled machine must be checked before start­up. Enclosures (coupling
protection, contact guard) must be fitted!
Overload conditions during start­up cannot be excluded. If the coupling breaks
through overload, metal parts may fly off and cause personal injury and/or material
damage.
For the oil quantity, refer to the dimensioned drawing.
The coupling must run with little noise and without vibration. Irregular behaviour must be treated as a fault
requiring immediate remedy. In case of fault the drive must be stopped at once. The necessary measures
for repair must be taken in accordance with the safety regulations applying.

Faults, causes and remedy

5.1

Possible cause of the fault:

Change of alignment:
­ Rectify cause of alignment change (e.g. loose foundation bolts).
­ Align the coupling.
­ Check the axial fastening and, if necessary, adjust.
Insufficient lubricant:
­ Check lubricant supply.
5.2

Incorrect use

Failure to observe these instructions may result in breakage of the coupling.
Danger from flying fragments!
5.2.1

Frequent faults when selecting the coupling and/or coupling size

•
Important information for describing the drive and the environment are not communicated.
•
System torque too high.
•
System speed too high.
•
Application factor not correctly selected.
•
Chemically aggressive environment not taken into consideration.
•
The ambient temperature is not permissible.
•
Finished bore with inadmissible diameter and/or inadmissible assigned fits.
•
Machining of parallel keyways of which the width across corners is greater than the width across
corners of the parallel keyways to DIN 6885/1 with a maximum permissible bore.
•
The transmission capacity of the shaft­hub connection is not appropriate to the operating conditions.
•
Maximum load conditions are not being taken into consideration.
•
Dynamic load conditions are not being taken into consideration.
