KSK
5 Installation
Note
If the shafts are damaged, this may lead to failure of
the axis synchronization.
• Check whether the connecting shaft shows signs
of transport or storage damage, particularly with
regard to kinks, buckles or bends.
A KSK that exhibits such damage is not suitable
for further use.
Note
If the metal shock absorbers of the couplings are
damaged this may lead to failure of the axis syn­
chronization.
• Check whether the metal shock absorbers of the
coupling exhibit any kinks, buckles or runout.
A coupling that exhibits such damage is not suit­
able for further use.
• Make sure that the maximum permitted static slide offset Dw of
the axes is maintained over the complete positioning path
(è Fig. 23 to Fig. 26). The diagram is already reduced by the
dynamic share of the offset by the shaft torsion.
The slide offset w results from:
– the offset of different slide feedsk
– mounting tolerances.
Ascertaining the offset k:
• Measure the positioning paths k1 and k2 of the slides on both
axes at the same number of revolutions of the drive trunnion (if
possible over the complete stroke range).
The offset k results from the path difference.
