1 Safety Instructions
This installation and operation manual is an essential component of the coupling
delivery. Always keep this manual in a readily accessible place near the coupling.
Take care that all persons being charged with the installation, operation, maintenance and
repair of the coupling have read and understood this manual and that all instructions con-
tained therein are carefully observed in order to:
-avoid danger to life and limb of the user or third persons,
-ensure the operational safety of the coupling,
-preclude operation failures and environmental damages due to wrong handling and
misuse.
The relevant instructions and regulations regarding safety at work and environmental protec-
tion have to be observed while transporting, mounting and dismounting the coupling.
The coupling shall be operated, mounted, maintained and repaired by authorized, trained and
instructed personnel only.
In the interest of further development, we reserve the right to carry out modifications serving

2 Technical Description
The RINGFEDER® TNS SX coupling is a torsionally flexible, puncture proof claw coupling
which is particularly suited for use with hydrodynamic high-speed couplings.
It compensates for angular, radial and axial shaft misalignments within defined limits. The
coupling transmits torque through elastic buffers loaded in shear. These buffers come in
Perbunan (Pb), Pb82 as a standard, or polyurethane (Vk), and are connected to each other
to form an elastic buffer ring.
This buffer ring dampens shocks and torsional vibrations and is resistant to oil.
Buffer rings made of Perbunan are electrically conductive.
The coupling is suitable for use in every direction of rotation and installation position.
2.1 Intended Application
•The coupling must only be operated in normal industrial atmospheres. Since aggressive
media may attack the coupling components, screws and elastic buffer rings, they repre-
sent a risk for the operational safety of the coupling. Consult RINGFEDER POWER
TRANSMISSION in such cases.
•In order to ensure trouble-free and reliable operation, the coupling has to be sized
according to the design specifications, e.g. according to DIN 740, part 2, (or acc. to
Paper & Tech Paper “Elastomer Jaw Couplings“), with a service factor appropriate for
the service conditions.
•Except for the production of a finish bore with keyway, no further modifications are
allowed to be carried out on the coupling!
•The coupling shall only be used and operated within the frame of the conditions as
defined in the performance or delivery contract.
•Any change in the operation conditions or service parameters requires the verification of
the coupling design.

3 Coupling Marking
3.1 Marking of Buffer Rings
The buffer rings are marked on the face of one buffer element as follows:
- Coupling size and material abbreviation (Vk for Polyurethane or Pb for Perbunan)
- Year of construction
-Pb72 = buffer ring of Perbunan, 72 Shore(A) / black
-Pb82 = buffer ring of Perbunan, 82 Shore(A) / black
-VkB = buffer ring of Polyurethane, 83 Shore(A) / blue
-VkR = buffer ring of Polyurethane, 93 Shore(A) / red
-Vk60D = buffer ring of Polyurethane, 60 Shore(D) white/beige
4 Storage
On receipt of the goods, immediately check that all parts are on hand and are as ordered.
Eventual shipping damages and/or missing parts have to be reported in writing.
The coupling parts can be stored in the delivered state in a dry place under roof at normal
ambient temperatures for a time period of 6 months. Storage for a longer period requires the
application of a long-term preservation. (Please consult RINGFEDER POWER
TRANSMISSION in this respect.) The buffer rings must not be exposed to ozonic media,
direct sun light or intensive light sources with UV light. The air humidity should not exceed
65 %. If the parts are properly stored, the quality characteristics of the elastic buffer rings
remains almost unchanged for up to three years.

The torques TKnom and TKmax. are valid for:
-Ambient temperatures of –30°C up to +30°C for Polyurethane (Vk),
-Ambient temperatures of -30°C up to + 60°C for Perbunan (Pb)
-Operation within the range of the specified alignment values.
For determining the size of the coupling according to DIN 740, part 2, (or to Paper &
Tech Paper “Elastomer Jaw Couplings“) various factors have to be taken into account:
-the temperature factor Sυin case of higher temperatures,
-the start-up factor Sz depending on the frequency of starts,
-the shock factor SA, SLdepending on the service conditions.
For circumferential speeds above 22 m/s, referred to the nominal size of the coupling, we
recommend balancing the steel parts of the coupling.

7 Installation
7.1 To be observed prior to installation
• Danger of injuries!
• Disconnect the drive before carrying out any work on the coupling!
• Secure the drive against unintentional re-start and rotation!
• Incorrectly tightened bolts can cause serious personal injuries and
property damages!
• Assemble the coupling outside of the danger zone. Take care that
suitable transportation means are at disposal and that the transpor-
tation ways are free of obstacles. Do not use tools containing iron
when mounting the parts in explosive areas.
• In compliance with accident prevention regulations, you are
obliged to protect all freely rotating parts by means of permanently
installed guards/ covers against unintentional contact and falling
down objects.
• To avoid sparks, the covers for couplings used should be made of
stainless steel!
• As a minimum, the covers have to fulfil the requirements of protec-
tion type IP2X.
•
The covers have to be designed to prevent dust from depositing on
the coupling.
• The cover must not contact the coupling or impair the proper
function of the coupling.
•Make sure that the speeds, torques and ambient temperatures as stated in chapter 6
‘Technical Data’ are not exceeded.
•The maximum permissible bore diameters must not be exceeded.
•Check whether the shaft-hub connections safely transmit the occurring operating torques.
•The standard tolerance of RINGFEDER® TNS for finish bores is fit H7.
•Standard keyways comply with DIN 6885, sheet 1.
•Check the dimensions and tolerances of shafts, hub bores, keys and keyways.
•Set screws as required.

7.2 Finish bores
The following procedure has to be observed to produce a finish bore in a coupling hub:
• Clean and remove all preservatives from the coupling hub.
• Mount the coupling hub between the surfaces marked with
and carefully align the
coupling hub according to the claw pattern.
• The values for ød1max listed in table 1 are valid for keyed connections according to DIN
6885/1 and must not be exceeded.
• Select the bore fit so that an interference fit such as H7/m6 results when mating it with the
shaft tolerance.
• Axially lock the hub, for example by means of a setscrew on the back of the hub above
the keyway
Consult RINGFEDER POWER TRANSMISSION in case of other shaft-hub connections.
• The stated maximum bore diameters are valid for keyed connec-
tions according to DIN 6885/1 and must not be exceeded.
• If these values are exceeded, the coupling can break.
• Flying off coupling fragments are a danger to life!

7.3 Coupling installation
• Remove the elastic buffer ring (Fig.
3, pos. 1).
• Prior to installation, carefully clean
the bore of the coupling hub and the
shaft end. The surfaces must be
clean, dry and free of grease.
• For larger couplings use suitable
mounting tools and hoisting devices
such as cranes or pulley blocks.
• Mount the coupling hub in the
proper position on the shaft end
(Fig. 3, pos. 2).
Note:
To facilitate mounting, the hub can be uniformly heated to 80°C to 120°C.
Warning!
Always wear heat-resistant gloves to protect yourself against
injuries due to hot coupling components!
• Mount the hub in such a manner that
the shaft end is flush with the inner
bore opening (Fig. 4).
Observe deviant agreements, which
may exist!
• When tightening setscrews, secure
them with an adhesive, such as e.g.
Loctite 222, to prevent the screws
from working loose and dropping out.
• Mount the aluminium coupling flange
to the flange connection. When join-
ing the parts, take care that they do
not get canted at the centering seat.
(Fig. 3, pos. 2).
RINGFEDER® TNS SX
BAWS 010-GBR-1

Fig. 5
ATTENTION!
The contact surfaces of the coupling hub and flange connection must be clean, dry
and free of grease. Balanced parts are match marked to each other.
Let the hot hub cool down to ambient temperature, before inserting the buffer ring.
• To facilitate mounting, the buffer ring
can be coated with a lubricant (for
ex. talcum for Perbunan Pb, or
commercial roller bearing grease for
polyurethane Vk).
• Install the buffer ring on one of the
coupling halves.
• Push together the shaft end with the
mounted coupling half and the cou-
pling flange (Fig. 5).
• Align the coupling in accordance
with the instructions given in chapter
8 ‘Coupling Alignment’.
8 Coupling Alignment
Danger of Injuries!
Disconnect the drive before carrying out any work on the
coupling.
Secure the drive against unintentional re-start and rotation!
Note:
Accurate alignment of the coupling prolongs the lifetime of the
elastic buffer ring.
It is of utmost importance to observe the recommended alignment
values. Exceeding the permissible misalignment values results in
coupling damages and failures!
When aligning the cold equipment take into account the expected thermal growth of the
components, so that the permissible misalignment values for the coupling are not
exceeded in operation.
Be aware that the coupling under misalignment imposes restoring forces on the adjacent
shafts and bearings. Take into account that the larger the misalignment, the greater the
restoring forces will be.
The maximum permissible misalignments stated in tables 2 to 4 are guiding values. We
recommend utilizing these values up to 50 % only when aligning the coupling, so as to
have sufficient reserves for thermal growth, foundation settlings etc. during service.
In special applications with high demands on quiet running characteristics or higher
RINGFEDER® TNS SX
BAWS 010-GBR-1

- 12 -
speeds, alignment accuracies of ≤0,1mmmay be necessary for the three alignment
levels.
If the coupling is mounted in a closed housing/ guard, so that alignment at a later point of
time will no longer be possible, make sure that the geometry and the fitting accuracy of
the contact surfaces ensure true alignment of the shafts within the specified tolerances
during service.
8.1 Angular Misalignment
• Measure one complete revolution
(360°) on the face of the outer di-
ameter. Determine the largest devia-
tion Kw1 and the smallest deviation
Kw2 (Fig. 6). Calculate the angular
misalignment:
∆Kw = Kw1 – Kw2.
• When aligning, observe the max.
permissible angular misalignment
∆Kwmax acc. to table 2.
• The values are applicable for a
reference speed of 1500 rpm.

Calculate the radial misalignment:
∆Kr = 0,5 x (Kr1 – Kr2). Observe the
preceding sign of the measured val-
ues.
• When aligning, observe 50 % of the
maximum permissible radial mis-
alignment ∆Kr max acc. to table 3.

9 Operation
When operating the coupling, its specific technical data have to be carefully observed (see
chapter 6 ‘Technical Data’). These values must never be exceeded without the prior written
approval by RINGFEDER POWER TRANSMISSION.
In order to ensure trouble-free and reliable performance of the coupling, the coupling has to
be designed according to the selection specifications, e.g. according to DIN 740, part 2, (or
acc. to Paper & Tech Paper “Elastomer Jaw Couplings“), with a service factor appropriate
to the service conditions. Any change in the service conditions or service parameters
always necessitates the verification of the coupling design.
Danger of injuries!
Disconnect the drive before carrying out any work on the coupling!
Secure the drive against unintentional re-start and rotation!
Improperly tightened screws may cause parts to fly off what leads
to most serious personal injuries and property damages!
Before putting the coupling into operation, check the align
ment and
all screwed connections for correct tightening torque and firm fit!
Before starting up the equipment, install all protective guards in
order to avoid unintentional contact with freely moving or rotating
parts.
To avoid sparks, the covers for couplings used should be made of
stainless steel!
The covers have to comply with protection type IP2X as a mini-
mum.
The cover shall be designed to prevent dust from depositing on
the coupling parts.
The cover must not touch the coupling and impair the proper
operation of the coupling.
For equipment group I in mining applications, pay careful attention
to the particular hazards that exist when using aluminium parts!
While operating the coupling, pay attention to:
Changes in operation noises
Occurring vibrations
Attention!
• Disconnect the drive immediately, if any irregularities are observed while operating
the coupling!
• Identify the cause for the problem using table 5 “Operation Faults and Possible Causes“
and correct the fault.
The listed problems are some examples to assist you in troubleshooting.
• All the machinery components and operation modes have to be considered for the
determination and correction of faults!

10 Maintenance
The flexible coupling RINGFEDER® TNS SX only requires little maintenance during
operation. The elastic buffer ring is subject to wear. The time at which the wear limit of the
elastic buffer ring is reached depends on the service parameters and application conditions.
On the occasion of routine inspections or maintenance of the equipment, check:
• alignment of coupling,
• state of the elastomer, and
• remove dust deposits from coupling parts and buffer ring.
10.1 Wear Inspection on the Buffer Ring
Danger of injuries!
Disconnect the drive before carrying out any work on the
coupling!
Secure the drive against unintentional re-start and rotation!
Perform a visual inspection and a wear inspection of the buffer ring after
2000 hours, or after 3 months at latest, after the first start-up of the equip-
ment. If only minor wear or no wear is observed, further inspections of the
plant can be carried out at regular intervals of 4000 hours, however, at least
once a year, if the operating modes and conditions of the plant remain
unchanged. However, should you observe excessive wear on the occasion
of this first inspection already, check whether the cause for the problem is
listed in table 5 “Operation faults and possible causes”. In such a case, the
inspection intervals must be adapted to the prevailing service conditions.
On the occasion of routine inspections or maintenance work on the drive equipment, or after
3 years at latest:
• Replace the elastic buffer ring.
• If the wear limit has been reached or exceeded, replace the buffer ring immediately,
irrespective of the inspection intervals of the equipment.
• Check the alignment of the coupling.
• Remove dust deposits from the coupling components and buffer ring.

• Replace the elastic buffer ring as
soon as the coupling has a distinct
torsional backlash, or if the wear
limit acc. to table 6 has been
reached.
• To check the wear of the elastomer,
the plant has to be shut down and
must be unloaded. Turn the cou-
pling halves in such a manner that
the claws rest without clearance at
the buffer of the elastic ring.
• Measure the claw distance ‘V’ in
circumferential direction across the
buffers to which the claws rest on
both sides (see fig. 9). The adjacent
buffers do not contact the claws.
• Repeat this measurement on the
adjacent buffers after having turned the couplings halves against each other in opposed
direction.
• If dimension ‘V’ attains or exceeds the value ‘Vmin’ listed in table 6 for the individual
coupling sizes, the elastic buffer ring has to be replaced immediately.
Table 6 Distance dimension Vmin for wear measurement while the equipment is at
standstill:

10.3 Replacement of buffer ring
Danger of injuries!
Disconnect the drive before carrying out any work on the
coupling!
Secure the drive against unintentional re-start and rotation!
• Push back one of the coupling
halves (Fig. 10).
• Remove the buffer ring (part 020).
• To facilitate mounting, the new
buffer ring can be coated with a
lubricant before installing it (e.g.
talcum for Perbunan Pb, or com-
mercial roller bearing grease for
Polyurethane Vk).
• Mount a new buffer ring of correct
material and size .
• Push the coupling halves together
again.
• Align the coupling according to the
instructions given in chapter 8 ‘Cou-
pling Alignment’.
Warning!
Before putting the equipment into service, all safety guards
must be installed to prevent unintentional contact with
freely rotating parts.
To avoid sparks, the covers for couplings used should be
made of stainless steel.
The covers have to fulfil the requirements of protection type
IP2X as a minimum.
The covers have to be designed to prevent dust from
depositing on the coupling parts.
The cover must not touch the coupling and impair the
proper operation of the coupling.
We do not assume any responsibility or warranty for any damages resulting from the use of
accessories or spare parts, which have not been originally manufactured by RINGFEDER
POWER TRANSMISSION.
11 Disposal
Disposal of the parts must be arranged in accordance with the regulations and laws of
the country where the equipment is installed.
