3 Function and application
The KSK connecting shaft synchronises the rotary motion of two parallel electric
toothed belt axes.
It is intended for transmission of rotary motion without additional external loads
in horizontal mounting position of the connecting shaft between axes EGC-...-TB
or ELGA-TB.

4 Transport and storage
Store the connecting shaft preferably at room temperature without external mech-
anical loads. Temperature stresses and extreme climatic conditions will damage
the couplings in particular.
5 Requirements for product use
NOTICE!
• Make sure that the items in this chapter are observed at all times.
This ensures that the product operates correctly and safely.
– Take into consideration the legal regulations applicable for the location as
well as:
– Instructions and standards
– Regulations of testing organisations and insurers,
– National specifications.
– Compare the limit values specified in these operating instructions with your
actual application (e.g. installation tolerances, forces, torques, temperatures,
masses, velocities).
Operation of the product in compliance with the relevant safety regulations
depends on adherence to the load limits.
– Remove transport packaging, such as films, caps and cardboard.
The material used in the packaging has been specifically chosen for its recyc-
lability (exception: oiled paper = residual waste).
– Use the product in its original status, without any unauthorised modifica-
tions.
– Take into consideration the ambient conditions at the location of use.
Corrosive environments (e.g. ozone) will reduce the service life of the
product.
– Take the tolerance of the tightening torques into account. Unless otherwise
specified, the tolerance is ±20%.
6 Installation
NOTICE!
Damaged shafts may lead to failure of axis synchronisation.
• Check whether the connecting shaft has transport or bearing damage, in par-
ticular kinks, dents or bends. A KSK with such damage is not suitable for fur-
ther use.
NOTICE!
Damaged metal bellows of the couplings may lead to failure of axis synchron
isation.
• Check whether the metal bellows of the coupling show kinks, dents or out-of-
roundness. A coupling with such damage is not suitable for further use.
Fig. 3
• Make sure that the maximum permissible static slide misalignment Δw of the
axes is
è 12.2 Max. permissible static slide misalignment at permissible drive
torquemaintained over the entire travel distance. The diagram is already
reduced by the dynamic component of the misalignment caused by the shaft
torsion.
The slide offset Δw is made up of the offset of:
– different slide feeds Δk
– due to mounting tolerances.
Fig. 4
• To determine the offset Δk, measure the travel distances 1 k1 and 2k2 of
the slides on both axes with the same number of revolutions of the drive
shafts (preferably over the entire stroke range).
The offset Δk results from the distance difference.

• Make sure that the permissible radial misalignment ΔKr is not exceeded.
The maximum permissible radial Δmisalignment Kr, which can still be com-
pensated by the bellows couplings, increases as the misalignment of the two
axes is reduced.
The interdependence of the two quantities:
è 12.1 Max. permissible radial misalignment for angular misalignment.
Fig. 6
• Compare the outer diameter of the coupling with the available installation
space. Depending on the size-length combination, the couplings may project
beyond the contour of the toothed belt axis.
• Observe the mounting instructions and the support distances in the operating
instructions for the axis.
for EGC
Fig. 7
NOTICE!
The asymmetrical product geometry of the EGC can lead to mounting errors.
• Note the different distances (LH and LV) between the guide centre and the
front and rear cover surfaces. Connection is possible at all four hollow shaft
ends.
EGC...TBKF...Z with shortened hollow shafts
Fig. 8
NOTICE!
Please note that the drive shaft may only be mounted on the front side of type
EGC-...-TB-KF-...-Z.
• Note that the nominal length L can be read from the KSK type code (e.g.
KSK-40-1000 èL = 1000 mm).
Place the toothed belt axes at the specified distance L from each other.

L ≙ clearance between the drive covers
Attach an X-axis to the basic assembly. Please observe the information in the
user manual of the axis.
Fig. 10
• Now attach the second X-axis. The axis must be aligned both in height and in
parallelism of the slide surfaces to each other.
First slightly tighten the retaining screws.
• Move the X-axis slides to the same end position.
• Attach the Y axis to the X axis slides.
• Move the Y axis back and forth over the entire traverse path of the X axes. The
second X-axis will then align itself definitively.
• Fasten the second X-axis while observing the alignment and the permissible
offsets Δk and ΔW è 12 Characteristic curves.
Check that the axes move smoothly again.
• Tighten the retaining screws.
6.1 Installation Processing
Fig. 11
• Remove the shaft cover on the desired connection side (e.g. with a screw-
driver).
• Push the included drive shaft into the hollow shaft of the EGC/ELGA until it
stops.
Fig. 12
• Tighten drive shaft with ring spanner 1, hold in position and tighten screw
with Allen key 2. Observe the tightening torque.
