Screw the setting nut onto the hub or clamping ring hub and hand-tighten it.
Hand-tighten the cap screw in the setting nut. Afterwards turn back the cap screw by half a rotation.
Mount the clamping ring onto the clamping ring hub. [Applies with hub design 6.1 only]
With the assembly please make sure that the
balancing bores of the clamping ring
(component 2.9) point towards the disk
spring(s).
Illustration 19: Notches of setting nut
Screw in the setting nut by means of a hook spanner (see
illustration 17 and table 8) until it cannot be turned any
more. Afterwards turn back the setting nut by one notch
(see illustration 19).
The torque pre-set corresponds to the minimum release
torque (see illustration 20) now.
Set the torque required as described in chapter 5.1.
The disk springs are operated in the negative
sector of the characteristic curve. Tightening
the setting nut causes a reduced release
torque. The release torque is increased by
untightening the setting nut.
Illustration 20: Spring characteristic
Remove the cap screw from the setting nut and paint with
Loctite (average strength). Afterwards screw in the cap
screw and tighten at the tightening torque T
A
specified in
table 7.
Unscrew the clamping screw of the clamping ring.
[Applies with hub design 6.1 only]
Disassemble the coupling from the auxiliary shaft.
!
Please bear in mind that setting the torque beyond the torque range (see chapter 1) may
result in misoperation and damage of the coupling.
In order to ensure an optimum torque setting, SYNTEX
®
-NC should be inspected after initial
disengagement processes and reset, if necessary.
If SYNTEX
®
-NC was pre-set only or set to the requested torque as per these
operating/assembly instructions, the torque should be considered as a reference value only.
For accurate torque setting we would recommend to inspect the torque by means of a
suitable measuring system and reset, if necessary.
We basically recommend to perform torque setting on KTR's test benches in order to
ensure the optimum accuracy of torque setting.
All screw connections must be secured against working loose additionally, e. g.
conglutinating with Loctite (average strength).
