Advice
2.4 Intended use
You may only assemble, operate and maintain the coupling if you
• have carefully read through the operating/assembly instructions and understood them
• are technically qualified and specifically trained (e. g. safety, environment, logistics)
• 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 state of the art at the time of printing of these operating/assembly instructions.
2.5 Coupling selection
!
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.
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 subjected 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 subjected 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.
2.6 Reference to EC Machinery Directive 2006/42/EC
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.

Storage, transport and packaging
3.1 Storage
The coupling hubs are supplied in preserved condition and can be stored in a dry and roofed place for 6 - 9 months.
The features of the coupling spiders (elastomers) remain unchanged for up to 5 years with favourable storage
conditions.
!
The storage rooms must not include any ozone-generating devices like e. g. fluorescent
light sources, mercury-vapour lamps or electrical high-voltage appliances.
Humid storage rooms are not suitable.
Make sure that condensation is not generated. The best relative air humidity is less than
65 %.
3.2 Transport and packaging
!
In order to avoid any injuries and any kind of damage always make use of proper transport
and lifting equipment.
The couplings are packed differently each depending on size, number and kind of transport. Unless otherwise
contractually agreed, packaging will follow the in-house packaging specifications of KTR.
4
Assembly
The coupling is generally supplied in individual parts. Before assembly the coupling has to be inspected for completeness.

4.2 Advice for finish bore
STOP
The maximum permissible bore diameters D (see 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 resp. axial runout (see illustration 4).
• Make absolutely sure to observe the figures for ØD.
• Carefully align the hubs when the finish bores are drilled.
• Provide for a setscrew according to DIN EN ISO 4029 with
a cup point or an end plate to fasten the hubs axially.
Illustration 5: Concentricity and axial runout
!
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.
KTR supplies unbored or pilot bored coupling components and spare parts only upon explicit request of the customer. These parts are additionally marked with the symbol .
Reference to unbored resp. pilot bored coupling components with explosion protection marking:
Basically the company KTR Systems GmbH supplies couplings resp. coupling hubs with explosion
protection marking as an unbored or pilot bored type only on explicit request of the customer. The
prerequisite is a declaration of exemption submitted by the customer assuming any responsibility
and liability for respective remachining performed on the product of KTR Systems GmbH.

4.3 Assembly of the coupling (general)


We recommend to inspect bores, shaft, keyway and feather key for dimensional accuracy
before assembly.

When disassembling the ROTEX® SH SPLIT EN-GJL hubs, small casting particles may come
loose from the cracked surface, but the function is not affected.
The cracked surfaces of the ROTEX® SH SPLIT hub halves must be inspected for cleanliness
before assembly.
If necessary, clean the cracked surfaces of the EN-GJL hubs with a wire bush to ensure an
optimal fit.
Please pay attention to the ignition risk in potentially explosive atmospheres!
!
With the assembly make sure that the distance dimension E (see table 1, 3 and 5) is observed to allow for axial clearance of the spider when in operation.
Disregarding this advice may cause damage to the coupling.
If used in potentially explosive atmospheres the setscrews to fasten the hubs as well as all
screw connections must be secured against working loose additionally, e. g. conglutinating
with Loctite (average strength).
4.4 Assembly of the hubs (axial 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.
• Mount the SPLIT hubs on the shaft of
driving and driven side (see illustration
6).
• The internal sides of the hubs must be
flush with the front sides of the shafts.
Illustration 6: Assembly of hubs
• Insert the spider in the cam section of the hubs on
the driving or driven side (see illustration 7).

4.4 Assembly of the hubs (axial assembly)
• Shift the power packs in axial direction until the distance dimension E is achieved (see illustration 8).
• If the power packs are already firmly assembled,
shifting the hubs axially on the shafts allows for setting the distance dimension E.
• Tighten the cap screws of the SPLIT hubs reciprocally by means of a suitable torque key to the tightening torques TA mentioned in table 1, 3 or 5.
• Fasten the SPLIT hubs by tightening the setscrews
DIN EN ISO 4029 with a cup point (tightening torque
see table 7).
Illustration 8: Assembly of coupling
• Centre the spider between the SPLIT hubs and check the dimensions E and S (see illustration 8 and chapter
1).

4.7 Displacements - alignment of the couplings
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 and avoid hazards with the use in potentially explosive atmospheres, the shaft ends must 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.
If used in potentially explosive atmospheres for explosion group IIC, only half of the displacement figures (see tables 8 and 9) is permissible.
!
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 simultaneously, the permissible displacement figures may only be used
proportionally (see illustration 14).
• Inspect with a dial gauge, ruler or feeler whether the permissible displacement figures of tables 8 and 9 can be
observed.

Start-up
Before start-up of the coupling, inspect the tightening of the setscrews in the hubs, the alignment and the distance
dimension E and adjust, if necessary, and also inspect all screw connections for the tightening torques specified.
If used in potentially explosive atmospheres the setscrews to fasten the hubs as well as all
screw connections must be secured against working loose additionally, e. g. conglutinating
with Loctite (average strength).
Finally the coupling protection against accidental contact must be fitted. It is required in accordance with
DIN EN ISO 12100 (Safety of Machinery) and directives 2014/34/EU and SI 2016 No. 1107 and must protect
against
• access with a little finger
• falling down of solid foreign objects.
The coupling protection is not part of KTR's scope of delivery and is the customer's responsibility. It must have
sufficient distance to the rotating components to avoid contact safely. Depending on the outside diameter DH of
the coupling, we recommend the following minimum distance:
ØDH to 50 mm = 6 mm, ØDH 50 mm to 120 mm = 10 mm, ØDH from 120 mm = 15 mm.
Please check if a proper enclosure (ignition protection, coupling protection, contact protection) has been mounted
and the operation of the coupling is not affected by the enclosure. The same applies for test runs and rotational
direction inspections.
The cover may provide for openings intended for necessary heat dissipation. These openings have to comply with
DIN EN ISO 13857.

Start-up
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.
If the couplings are used in locations subject to dust explosion and in mining the user must
make sure that there is no accumulation of dust in a dangerous volume between the cover
and the coupling. The coupling must not operate in an accumulation of dust.
For covers with unlocked openings on the top face no light metals must be used if the couplings are used as equipment of equipment group ll (if possible, from stainless steel).
If the couplings are used in mining (equipment group l M2), the cover must not be made of
light metal. In addition, it must be resistant to higher mechanical loads than with use as
equipment of equipment group ll.
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.
Coating of coupling:
If coated (priming, paintings, etc.) couplings are used in potentially explosive atmospheres,
the requirements on conductibility and coating thickness must be considered. With paintings up to 200 µm electrostatic load does not have to be expected. If thicker paintings resp.
coatings up to a layer thickness of a maximum of 2.0 mm are applied, the couplings are not
permissible for gases and vapours of category IIC in potentially explosive areas, but only for
gases and vapours of category IIA and IIB.
This also applies for multiple coatings exceeding an overall thickness of 200 µm. Make sure
with painting or coating that the coupling components are conductively connected with the
device/devices to be connected so that the equipotential bonding is not impeded by the
paint or coat applied. Basically painting of the spider is not admitted to ensure an equipotential bonding.
In addition, make sure that the marking of the coupling remains legible.

Breakdowns, causes and elimination
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.
The coupling can become a source of ignition with improper use.
Directive 2014/34/EU and UK directive SI 2016 No. 1107 require special care by the manufacturer and the user.
General failures with improper use:
• Important data for the coupling selection are not forwarded.
• The calculation of the shaft-hub-connection is 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 are 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.

Disposal
In respect of environmental protection we would ask you to dispose of the packaging resp. products on termination of their service life in accordance with the legal regulations resp. standards that apply.
• Metal
Any metal components have to be cleaned and disposed of by scrap metal.
• Nylon materials
Nylon materials have to be collected and disposed of by a waste disposal company.
8
Maintenance and service
ROTEX® 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, inspect the
alignment of the coupling and re-align the coupling, if necessary.
• The coupling components have to be inspected for damages.
• The screw connections have to be inspected visually.
With the use in potentially explosive atmospheres observe chapter 10.2 "Inspection intervals for couplings in potentially explosive atmospheres".
9
Spares inventory, customer service addresses
We recommend to store major spare parts on site to ensure the readiness for use of the machine in case if a
coupling fails.
Contact addresses of the KTR partners for spare parts and orders can be obtained from the KTR homepage at
www.ktr.com.

observed.
An inspection of the torsional backlash and a visual inspection of the flexible spider must
be performed after 3,000 operating hours for the first time, at the latest after 6 months after start-up of the coupling.
If you note insignificant or no wear on the spider upon this initial inspection, further inspections can each be performed after 6,000 operating hours or at the latest after 18
months, provided that the operating parameters remain the same.
If you note significant wear during the initial inspection so that it would be recommendable to replace the spider, please find out the cause according to the table „Breakdowns“, if possible.
The maintenance intervals must be adjusted to the modified operating parameters without fail.
An inspection of the torsional backlash and a visual inspection of the flexible spider must
be performed after 2,000 operating hours for the first time, at the latest after 3 months after start-up of the coupling.
If you note insignificant or no wear on the spider upon this initial inspection, further inspections can each be performed after 4,000 operating hours or at the latest after 12
months, provided that the operating parameters remain the same.
If you note significant wear during the initial inspection so that it would be recommendable to replace the spider, please find out the cause according to the table „Breakdowns“, if possible.
The maintenance intervals must be adjusted to the modified operating parameters without fail.
Clamping hubs (SPLIT hubs) without feather keyways may be used in category 3 only and
are marked with category 3 accordingly.

10.3 Standard values of wear
In case of backlash > X mm, the flexible spider must be replaced.
Monitoring of the general condition of the coupling can be done both at standstill and during operation. If the
coupling is tested during operation, the operator must ensure an appropriate and proven test procedure (e. g.
stroboscopic lamp, high-speed camera, etc.) which is definitely comparable to testing at standstill. If any distinctive features occur, an inspection must be made with the machine stopped.
Reaching the limits for replacing depends on the operating conditions and the existing operating parameters.
In order to ensure a long service life of the coupling and avoid hazards with the use in potentially explosive atmospheres, the shaft ends must 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.
