10.2 Wear Inspection - Equipment at standstill
•
Replace the elastic buffer ring as soon
as the coupling has a distinct torsional
backlash, or if the wear limit acc. to ta-
ble 7 has been reached.
•
To inspect the wear of the elastomer,
the plant has to be shut down and must
be unloaded. Turn the coupling halves
in such a manner that the claws rest
without clearance at the buffers of the
elastic ring.
•
Measure the claw distance ‘V’ in
circumferential direction across the buff-
ers to which the claws rest on both
sides. The adjacent buffers do not contact
the claws.
•
Repeat this measurement on the adjacent buffers after having turned the couplings
halves against each other in opposed direction.
•
If the dimension ‘V’ attains or exceeds the value „V
min
“ listed in table 7 for the individual
coupling sizes, the elastic buffer ring has to be replaced immediately.

Upon completion of the wear measurement, re-install all the protective devices and covers.
