With assembly, operation and maintenance of the coupling it has to be made sure that the
entire drive train is secured against accidental switch-on. You may be seriously hurt by
rotating parts. Please make absolutely sure to read through and observe the following
safety indications.
All operations on and with the coupling have to be performed taking into account "safety first".
Please make sure to switch off the power pack before you perform your work on the coupling.
Secure the power pack against accidental switch-on, e. g. by providing warning signs at the place of switch-on
or removing the fuse for current supply.
Do not reach into the operating area of the coupling as long as it is in operation.
Please secure the coupling against accidental contact. Please provide for the necessary protection devices
and covers.
You may only assemble, operate and maintain the coupling if you
have carefully read through the operating/assembly instructions and understood them
had technical training
are authorized by your company
The coupling may only be used in accordance with the technical data (see chapter 1). Unauthorized modifications
on the coupling design are not admissible. We will not assume liability for any damage that may arise. In the
interest of further development we reserve the right for technical modifications.
The ROTEX®
described in here corresponds to the technical status at the time of printing of these
operating/assembly instructions.
!
For a permanent and failure-free operation of the coupling it must be selected according to
the selection instructions (according to DIN 740 part 2) for the particular application (see
catalogue drive technology "ROTEX®
").
If the operating conditions (performance, speed, modifications on engine and machine)
change, the coupling selection must be reviewed.
Please make sure that the technical data regarding torque refer to the spider only. The
transmittable torque of the shaft-hub-connection must be reviewed by the customer and is
subject to his responsibility.
For drives subject to torsional vibrations (drives with cyclic stress due to torsional vibrations) it is necessary to
perform a torsional vibration calculation to ensure a reliable selection. Typical drives subject to torsional vibrations
are e. g. drives with diesel engines, piston pumps, piston compressors etc. If requested, KTR will perform the
coupling selection and the torsional vibration calculation.
The couplings supplied by KTR should be considered as components, not machines or partly completed
machines according to EC Machinery Directive 2006/42/EC. Consequently KTR does not have to issue a
declaration of incorporation. For details about safe assembly, start-up and safe operation refer to the present
operating/assembly instructions considering the warnings.

The maximum permissible bore diameters d (see table 1
to 5 in chapter 1 - technical data) must not be exceeded. If
these figures are disregarded, the coupling may tear.
Rotating particles may cause danger to life.
Hub bores machined by the customer have to observe
concentricity or axial runout, respectively (see illustration
7).
Please make absolutely sure to observe the figures for
Ø dmax.
Carefully align the hubs when the finish bores are drilled.
Please provide for a setscrew according to
DIN EN ISO 4029 with a cup point or an end plate to fasten
the hubs axially. Illustration 7: Concentricity and axial run-out
!
The customer bears the sole responsibility for all machining processes performed
subsequently on unbored or pilot bored as well as finish machined coupling components
and spare parts. KTR does not assume any warranty claims resulting from insufficient
remachining.

If a feather keyway is intended to be used in the hub, it should correspond to the tolerance ISO JS9 (KTR
standard) with standard operating conditions or ISO P9 with complicated operating conditions (frequently
alternating torsional direction, shock loads, etc.). The keyway should preferably be located between the cams.
With axial fastening by setscrews the tapping should be located on the keyway except for Al-D which should be
located opposite the keyway.
The transmittable torque of the shaft-hub-connection must be reviewed by the customer and is subject to his
responsibility.
We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.
Heating the hubs lightly (approx. 80 °C) allows for an easier mounting on the shaft.
STOP
Touching the heated hubs causes burns.
Please wear safety gloves.
!
With the assembly please make sure that the distance dimension E (see table 1 to 5) is
observed to allow for axial clearance of the spider when in operation.
Disregarding this advice may cause damage to the coupling.
Shift the brake drum/disk onto the FN hub (see
illustration 8). Hand-tighten the components first.
Tighten the cap screws by a suitable torque key to
the tightening torques TA specified in table 1.
Secure the screws against working loose by means
of an adhesive (e. g. Loctite 243).
Mount the hub and FN hub with the brake drum/disk
onto the shaft of the driving and driven side. The FN
hub has to be installed on the shaft end on which
the bigger mass moment of inertia becomes
operative (see illustration 9).
Illustration 8: Assembly of brake drum/disk onto the FN hub
Illustration 9: Assembly of hub and FN hub with brake drum/disk
The maximum braking torque must
not exceed the maximum torque
(TKmax) of the coupling.

Insert the spider into the cam section of the hub (see
illustration 10).
Shift the power packs in axial direction until the distance
dimension E is achieved (see illustration 1 to 3).
If the power packs have already been firmly assembled,
shifting the hubs axially on the shafts allows for adjusting
dimension E (see illustration 1 to 3).
Fasten the hubs by tightening the setscrews
DIN EN ISO 4029 with a cup point (tightening torque see
table 6). Illustration 10: Assembly of spider
!
Having started up the coupling, the tightening torque of the screws and the wear of spider
have to be inspected at regular maintenance intervals and the spider has to be replaced, if
necessary.
The displacement figures specified in tables 8 and 9 provide for sufficient safety to compensate for external
influences like, for example, thermal expansion or foundation settling.
!
In order to ensure a long service life of the coupling, the shaft ends have to be accurately
aligned. Please absolutely observe the displacement figures specified (see tables 8 and 9).
If the figures are exceeded, the coupling will be damaged.
The more accurate the alignment of the coupling, the longer is its service life.
Please note:
The displacement figures specified in tables 8 and 9 are maximum figures which must not arise in parallel.
If radial and angular displacements arise at the same time, the permissible displacement values may only be
used proportionally (see illustration 12).
Please inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of tables 8 and 9
can be observed.

Before start-up of the coupling, inspect tightening of the setscrews in the flange hubs, the alignment and the
distance dimension E and adjust, if necessary, and also inspect all screw connections for the tightening torques
specified, dependent on the type of coupling.
Finally the coupling protection against accidental contact must be fitted. It is required in accordance with
DIN EN ISO 12100 (Safety of Machinery) and directive 2014/14/EU and must protect against
access with the little finger
falling down of solid foreign objects.

The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with
DIN EN ISO 13857.
The cover must be electrically conductive and included in the equipotential bonding. Bellhousings (magnesium
share below 7.5 %) made of aluminium and damping rings (NBR) can be used as connecting element between
pump and electric motor. The cover may only be taken off with standstill of the unit.
During operation of the coupling, please pay attention to
different operating noise
vibrations occurring.
!
If you note any irregularities with the coupling during operation, the drive unit must be
switched off immediately. The cause of the breakdown must be specified by means of the
table „Breakdowns“ and, if possible, be eliminated according to the proposals. The potential
breakdowns specified can be hints only. To find out the cause all operating factors and
machine components must be considered.
The below-mentioned failures can lead to a use of the ROTEX®
coupling other than intended. In addition to the
specifications given in these operating/assembly instructions make sure to avoid such failures.
The errors listed can only be clues to search for the failures. When searching for the failure the adjacent
components must generally be considered.
General failures with use other than intended:
Important data for the coupling selection were not forwarded.
The calculation of the shaft-hub-connection was not considered.
Coupling components with damage occurred during transport are assembled.
If the heated hubs are assembled, the permissible temperature is exceeded.
The clearance of the components to be assembled is not coordinated with one another.
Tightening torques have been fallen below/exceeded.
Components are mixed up by mistake/assembled incorrectly.
A wrong or no spider is inserted in the coupling.
No original KTR components (purchased parts) are used.
Old/already worn out spiders or spiders stored for too long are used.
Maintenance intervals are not observed.

is a low-maintenance coupling. We recommend to perform a visual inspection on the coupling at least
once a year. Please pay special attention to the condition of the coupling spiders.
Since the flexible machine bearings of the driving and driven side settle during the course of load, please
inspect the alignment of the coupling and re-align the coupling, if necessary.
The coupling parts have to be inspected for damages.
The screw connections have to be inspected visually.
!
Having started up the coupling the tightening torques of the screws have to be inspected
during the usual inspection intervals.
A basic requirement to ensure the readiness for use of the coupling is a stock of the most important spare parts
on site.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
www.ktr.com.
KTR does not assume any liability or warranty for the use of spare parts and accessories
which are not provided by KTR and for the damages which may incur as a result.
