ARPEX 8706 en
Operating instructions 10/2017
WARNING
Risk of serious injury through flying fragments
Risk of serious injury through flying fragments and/or risk of damage to the coupling.
– Locking nuts must only be used three times, to guarantee the locking properties.
– Adhere to specified tightening torques. Observe the instructions relating to cleaning and/or treatment
of the bolts with auxiliary materials.
6.9 Alignment
Observe the safety instructions in section 6.1, "General information on fitting"!
In general the machine parts to be joined together should always be optimally aligned. Since this is often
done with highprecision, optical equipment before the coupling components are assembled, in such
cases the alignment should be checked during or after assembly of the coupling only as an additional
safeguard. The fastening must be removed before aligning. The design of the fastening is shown on the
orderspecific drawing of the coupling.
6.9.1 Aligning with distance bush
Observe the safety instructions in section 6.1, "General information on fitting"!
Unscrew the cheesehead bolts from the fastening and remove the distance bushes (see figure 33).
Fig. 33: Removing the fastening in case of distance bush
When aligning the machine parts, in case of modules with distance bush measure with a sliding caliper
gauge the distance "S1" (see figure 34) between the coupling flanges.
Note
The permissible values of "S1" are given in the table "Fitting data" on the orderspecific drawing of the
coupling.
