COMBINO driving power pack Bevel gear with ROTEX® coupling
Several problems with rigid combinations have arisen inthe field. Rigid shaft connections cause stress and highdynamic reactions to adjacent components. On mostvehicles shock and vibration load is caused on the onehand by existing power packs and on the other hand bythe way of moving. Elasticity provides for more safety inthe power train.

Successful in railway technology and traffic engineering
With more than 30 years of experience in the field ofrailway drives and traffic engineering our intention ismore than only introducing KTR products: We areobliged to design new products with a further devel-opped technology for the future.This leaflet serves for providing you with new ideas how to adapt modified "simple" mechanics to high-tech-nology applications.Different outlines for railway traffic request for differentsolutions.When being designed, drive systems are adapted specifically to the power train and its components incooperation with the customer.
General description
Extraordinary requirements, e. g. higher performancewhile maintaining the expenses, are necessary toobserve in the global market in order to be competitive.Flexibility with high quality is required by all applicationsin traffic engineering.
Some examples of application: Redesigned KTR couplings are installed in the main drive (bogie) of:tramways, underground trains, trolley cars, mainlinelocomotives, operating locomotives, railway constructionvehicles as well as auxiliary drives for safety systems indoors and steps, current collectors, points setting devices, train tilting technology, etc.

Main drives:
torsion torsion
ROTEX® – torsionally flexible jaw couplings
Arguments in favour of using ROTEX® couplings in drive systems:
Quick axial plug-in assemblyReduction of maintenance costsFail-safeElasticity can be adaptedReduction of restoring forcesNoise reduction by structure-borne noiseseparationTorques up to a maximum of 35,000 Nm
The dynamic reactions between mechanical rigidcombinations are increasing. The drives of rail vehicles are becoming more compact, at the sametime having higher capacities. As a result the powertrain is subject to high loads and the shaft cou-plings damping vibrations between electric motorand gearbox are of special importance.
Here the plug-in ROTEX® coupling has proven itsworth. The damping in the main drive preventsearly wear on the driving components. The overalldriving comfort is increased.
The geometric shapes of a flexible coupling with the optimum involute nylon teeth and concave shape of the cams being loadedare extremely important for the success of such a product. Uniformcontacts of the elastomer parts – along with the resulting lowerloads – result in smooth running and a considerably longer servicelife of the drive system.

Main drives:RIGIFLEX®
Steel lamina couplings
Various sizes of RIGIFLEX®
couplings are used on the bogieof trains. The couplings are in-stalled between motor and gear-box as a hollow shaft combination.
RIGIFLEX®
Steel lamina couplings
RIGIFLEX® spec. is used betweenmotor and gearbox of tramways.Here the lamina set is particularlysuitable to compensate for highmisalignments.
The RADEX®-MK membrane coupling is used betweensingle bearing motors and gearboxes of train drives.The membranes from highly stiff spring steel compen-sate for axial and angular displacements. At the sametime the coupling serves as a bearing for the motorarmature.A redesigned slipping unit protects the drive, for exam-ple in case of short circuits of the motor, against ex-tremely high torque peaks. The slipping torque is setby the manufacturer. Special friction linings provide fora long service life and a high repeating accuracy evenwith frequent load peaks.

ROTEX® with RUFLEX® – torque limiter used on a diesel electriclocomotive between gearbox and electric motor.
A special high-quality frictionlining provides for dampingthe short circuit torques in the power train. The pre-setoverload unit allows more frequent slipping with higherreproducibility of the slippingtorque (no slip-stick effect).
