Then and now
The starting shot which launched the KTR Kupplungstechnik
(coupling technology) company was fired back in 1959 with
the introduction of our maintenance-free BoWex® curvedtooth gear coupling. This initial impulse was a key to forging the
company DNA and since then, we have repeatedly come up
with solutions in line with market requirements. The BoWex®
design, combining plastic and steel and resulting in low
wear, was followed by the first reasonably-priced torque
measuring shaft and the ROTEX® GS, the first backlash-free
branded coupling which became a DIN standard.

REVOLEX® KX-D –
on track in Frankfurt
Frankfurt Airport is in a euphoric mood - thanks to the
recent MiniMetro® connection between the impressive
architectural THE SQUAIRE and its associated multistorey car park. The single-carriage cars are cabledrawn over a distance of 300 metres on a raised track
18 metres above ground level. Up to 1,700 people an
hour can safely and comfortably travel in both directions. The MiniMetro® is fully automated, driverless
and operates 24 hours every day of the year. Such dependability is only possible when reliable components
are combined with a team that is capable of adapting
such constituent parts precisely to meet very specific
requirements. KTR has both of these components!
Engineered for the toughest requirements
In order to deliver a project as prestigious as the MiniMetro®
on schedule – without the delays associated with the notorious Berlin-Brandenburg airport – everyone involved has to
act in concert. This is exactly what 14 pairs of capable hands
belonging to our “Engineered Business“ competence team
orchestrated in the town of Rheine. This unique group are
specialists in customer-specific projects, an area in which
KTR has been successfully conducting business for decades
alongside classical batch production.
The Engineered Business team is an aggregation of all
KTR‘s strengths, enabling us to react more precisely to any
new customer demands. Experts from development, production and sales work hand-in-hand to create purposebuilt solutions which facilitate a unified orientation down the
entire line and makes sure that drive components do not
become part of a dead-end track. An 80-second ride in the
MiniMetro®, cruising at up to 50 km/h is evidence of just how
successfully our team works.
REVOLEX® KX-D for maximum torque
This supra-terrestrial movement is largely possible due to
four KTR high-performance REVOLEX® KX-D couplings employed in the drive. The REVOLEX® is proven quantity when
it comes to moving people or heavy loads under adverse
conditions. For years it has been helping transport winter
sports enthusiasts in cable cars and lifts to icy ski runs or
making sure that belt conveyors used in mining do not succumb to South America‘s scorching sun.

The high-performance coupling used for inclines was
precision-customised for horizontal use by the Engineered
Business team. Maximum demands on elasticity, stiffness,
ruggedness and service life had to be fulfilled. The torsionally flexible pin-and-bush REVOLEX® KX-D coupling is preferably employed in cases where high torques have to be
transmitted to large-diameter slow-rotating shafts. Thanks to
the use of high-tensile quenched and tempered steel as a
hub material, nominal torques of up to TKN 1.22 mil. Nm can
be achieved.
REVOLEX® KX-D with shiftable linkage
But torque is not everything. There is also rotational direction
to take into consideration as the cable car uses a reversing
drive and to guarantee a smooth reversal of rotation, the coupling has to function in a backlash-free manner. What‘s more,
there needs to be the option to readjust its zero backlash in
the course of time. As the drive works through two redundant
gears, the coupling design has to also be shiftable. But that‘s
not all! The coupling also has to function as an electrical insulator to prevent leakage currents from damaging the gear
wheels. This is really asking quite a lot of of a coupling but
the backlash-free REVOLEX® KX-D takes it all in stride!
In addition to its strong performance, the REVOLEX® KX-D
also scores well for its service-friendliness. Thanks to its
compact construction, its axial plug-in design and practical conical pins, the elastomer rings can easily be replaced
even when the coupling is assembled. As a result, neither the power packs of the driving or the driven side
need to be shifted if changing the pin connections after
years of operation. But that‘s still a long way off – the
MiniMetro® only recently began to roll.
According to schedule, the MiniMetro® will switch into
top gear at Easter 2013. We are convinced the
REVOLEX® KX-D will live up to its reputation and transport
millions of travellers to come.

tolerance for misalignment as well as maintenance-free operation. Meanwhile, the winch equipment benefits from the
REVOLEX® KX-D 105 failsafe pin-and-bush coupling.
Where ever strong forces come into play, safety has to
be in the foreground – and that is where KTR-STOP®
S-35-F A-30 emergency stop brakes, with up to 4,000 Nm
braking torque, guarantees a safe operation of the entire construction under the most adverse weather conditions.
Since the worldwide protests against the sinking
of the “Brent Spar“ oil platform in 1995, a race for
the most efficient disposal of “exhausted“ oil rigs
has begun. According to international-expert estimates, approximately 6,500 oil or gas platforms
worldwide will have served their time by 2025.
Disassembly and removal costs for the oil industry will run into billions. So as to physically and
financially shoulder this gigantic load, the Swiss
offshore service company Allseas is currently building the world‘s largest construction vessel – the
Pieter Schelte. The operating “muscles“ are flexed
via couplings, brakes and hydraulic components –
made by KTR.
We are happy to be lending a helping hand to Pieter
Schelte - the construction vessel will surely be a measure
of lifting and moving heavy loads on the high seas for
some time to come.
Technical data:
New horizons
The single-lift and pipe-laying vessel Pieter Schelte outclasses everything the world‘s oceans have ever seen.
This sea giant has been designed as a catamaran with
two 382 meter-long hulls joined in the middle so that the
vessel will have a record-breaking width of 117 m – more
than double that of any of today’s existing cargo ships. To
transport a platform, the Pieter Schelte will literally “embrace“ the rig with its eight lifting beams. This topsides
lift system is designed to hoist up to 48,000 tons at a
time – more than the weight of 80 fully-laden Super Airbus A380s. The largest compliant tower platforms weigh
anything up to 20,000 tons.
length: 382 m
width: 117 m

with brake disk
After lifting the topsides onto the vessel, the ship turns 180
degrees and then uses its jacket lift system to raise the
platform‘s support structure, weighing up to 25,000 tons.
The dismantled platform is then brought to a ship-breaking
yard where it can be disposed of in a risk-free, efficient and
environmentally friendly way. At present Pieter Schelte is in
dry dock at the Daewoo Shipbuilding and Marine Engineering
shipyard in South Korea. Completion is envisaged for the end
of 2013 and operational service is due to begin early 2014.

Fairs and Events
New products at the
Hanover Fair 2013
Just a few days to go. Between 8th and 12th April 2013
the Hanover Fair will open its doors and focus on
landmark innovations targeting productivity and efficiency. Situated at the heart of power transmission,
KTR products will be playing an important role. That
is why we are looking forward to introducing no less
than six innovations, offering greater safety, dynamics
and energy efficiency.
ROTEX® S-H with SPLIT-hubs
New: BoWex® HEW Compact – vigorous arguments for
variable-speed drives
In numerous industrial applications, such as industrial compressors, fixed-speed drives are being increasingly replaced
by the variable-speed variety. Although the latter types save
both energy and costs, they pose an enormous challenge to
coupling manufacturers. Accordingly, it has been necessary
for drives to be reconceived for a significantly broader load
case spectrum.
New: SYNTEX®-NC – more drive train safety
Overload systems are inconspicuous yet important drive-train
components. In the case of an overload, they isolate the input
from the output sides and, by doing so, prevent more extensive
damage. More and more, design engineers voice the wish for
compacter and lighter components. So instead of shrugging our
shoulders, our development engineers rolled up their sleeves
and came up with an answer – the new SYNTEX®-NC backlashfree overload coupling.
KTR has taken on this challenge with the BoWex® HEW
Compact. The new and highly flexible curved-tooth gear
coupling reliably absorbs vibrations occurring in drive trains.
As a non-failsafe coupling, it provides a greater degree of
safety. Should the system become blocked, the input and
output sections are separated and the torque transmission is
reliably disconnected. Thanks to this type of technology, the
risk of more extensive damage is minimised. The BoWex®
HEW Compact’s condensed construction and its axial plugin design also result in an easy assembly – perfect for electric motors, mobile hybrid drives as well as the retrofitting of
machines with variable speed drives.
SYNTEX®-NC
This innovative system stands out from the crowd thanks to
its power density, low mass moment of inertia and high reliability. The compact design of the backlash-free system delivers rapid-response characteristics. The hybrid construction,
which uses diverse and partly coated materials, ensures a
high degree of repeat accuracy and a long service life. Thanks
to its condensed shape and easy-to-assemble clamping
ring design, the new SYNTEX®-NC can be used in a broad
spectrum of compact drives. This makes it ideal for use in
machine tools, control and positioning technology, as well
as packing machines and special engineering applications.

New: ROTEX® S-H – fracture costs with SPLIT-hubs

zzPOLY-NORM® with T-PUR®
zzROTEX® T-PUR®
The new ROTEX® S-H breaks with the principles of
manufacturing conventional jaw couplings – quite literally! The hubs are made in a customary way, from grey
cast iron, but are mechanically separated through “cracking“ and then screwed to each other during assembly,
resulting in an extremely strong cohesion of the coupling
halves, providing with a simple yet perfect fit.
Come to see KTR live...
The flexible ROTEX S-H with SPLIT-hubs is exceptionally well suited for use in constricted installation spaces
and heavy drive trains since its hubs can be installed and
removed in a radial manner without the need to dismantle
the power packs.
