The GKN Stromag product range provides a wide range of cardan shaft intermediate couplings. The couplings are designed for use in piston machines for direct connection to a cardan shaft.
The a-side of the coupling can be bolted directly to an engine’s flywheel. The universal shaft is flange-mounted to the B-side of the coupling.
The GKN Stromag cardan shaft intermediate coupling is comprised of the combination of an element made from flexible rubber material with a bearing for the secure absorption of the reaction forces applied by a connected cardan shaft.
Three different series of the cardan shaft intermediate couplings have been developed in order to satisfy the differing requirements in relation to the system torque, torsion spring stiffness and reaction force.
The highly flexible GKN Stromag Periflexr cS series designs are preferred for standard applications.
The IGe series from the established highly flexible GKN Stromag Ge coupling product family is used for applications with high impact loads.
The GKN Stromag aG flange bearing (aFl) together with a disc coupling as a cardan shaft intermediate coupling is recommended for an angle of deflection greater than 5°.

The couplings can be used in a temperature range of between -50°c and +80°c. a specially developed synthetic rubber can be used for the aFl’s disc tire so that this can be used up to a temperature of 120°c.
The elastic elements may heat up as a result of their damping activities and reach higher temperatures than the ambient temperature. If the coupling is housed in a protective hood or cover, this must be taken into account, or adequate ventilation and heat discharge must be ensured.
The GKN Stromag cardan shaft intermediate couplings are available with eN 10204 approval in accordance with the classification society requirements.
The GKN Stromag cardan shaft intermediate couplings are available with an in-built fail-safe device. If there is a rupture in the flexible element, this forms a torsionally rigid connection subject to backlash between the drive and output sides due to intermeshing of the claws. emergency operation is possible for a limited period of time with restricted torque.
INSTrucTIoNS oN cHooSING THe couPlING SIze >
Static and dynamic characteristic values are available for the GKN Stromag cardan shaft intermediate couplings. These values can help in the choice of a coupling size which is suitable for the specific application. The key factors for this are the loads arising from the power transmitted and torsional vibrations. Stationary operating modes must be based on T
KN, T
KW and P
KV, while T
Kmax values are to be used for non-stationary operating modes.
GKN Stromag’s specialist departments can provide support with design, particularly in calculating the torsional vibrations. We therefore ask you to copy, complete and send us the questionnaire at the end of this catalog.
as a rule, flexible couplings represent the predetermined mechanical breaking point of a drive train. overloading a drive train therefore generally leads to failure of the flexible coupling element.
This characteristic is intentional and protects the entire system from unexpected damage. any consequential damage that could arise from the failure of the coupling must be taken into consideration in advance by the system designer and monitored or prevented through appropriate measures.

When stored appropriately, flexible rubber elements retain their properties over several years without any alterations.
It is essential that the stored parts are protected against oxygen, ozone, light, heat, moisture and solvents.
The storage temperature should no fall below +10°c and not exceed +25°c. all uV light sources are harmful and must be avoided. equipment that generates ozone, e.g. light sources and electric motors, must be kept away from the storage location.
The relative air humidity should not exceed 65%.
Solvents, fuels, lubricants, chemicals, acids, disinfectants may not be kept in the same storage area.
Further details can be found in the DIN 7716 sheet.

das periflex® cS concept The Periflex® cS couplings are highly flexible rubber couplings with a linear spring characteristic for connecting a cardan shaft directly to a diesel engine drive.
The ring element can be bolted directly to an engine’s flywheel. The universal shaft is flange-mounted to the B-side of the coupling. an deflection angle of the cardan shaft of up to 5° is generally permitted, larger angles are available on request.
The series covers the torque range from 560 to 14800 Nm. The connecting dimensions on the engine side primarily conform to Sae standard J620 or DIN 6281.
The cardan shaft side is available in a range of metric sizes, including for Spicer, mechanics or cross-toothed connections.
The Periflex® cS coupling is comprised of the combination of a ring element made from flexible rubber material with a bearing for the secure absorption of the reaction forces applied by a connected cardan shaft. The ring element is exclusively torsionally flexible. The bearing consists of an axial and radial friction bearing made from wear-free and maintenance-free composite material.
The metal parts of the GKN Periflex® cS coupling are made from high-quality cast as standard. The ring element is manufactured from natural rubber (Nr) in various rubber qualities and torsion spring stiffnesses. These allow precise adjustment to drives that are susceptible to torsional vibrations.

the GKN Stromag afl / pvN concept
The flange bearing is a bell that is mounted to the diesel engine. an axially mountable, plug-in, highly flexible GKN Stromag Periflexr disc tire arranged inside the bell transmits the torque from the flywheel to the cardan shaft.
The disc tire has a linear spring characteristic and ensures the balanced torsional vibration behavior of the system, while the integrated bearing transmits the cardan shaft’s reaction forces to the engine housing via the bell. This means that the crank shaft bearings are not exposed to the reaction forces. as a rule, the aFl can be use up to a deflection angle of 10°, larger deflection angles are possible on request, depending on the operating conditions.
The torque transferred by the series is determined by the GKN Stromag Periflexrdisc tire used. The torque range extends from 1,000 Nm to 20,000 Nm.
The bell’s connecting dimensions to the engine housing are based on Sae standard J617. The connecting dimensions to the flywheel on the engine side primarily conform to Sae standard J620 or DIN 6281.
The cardan shaft side is available in a range of metric sizes, including for Spicer, mechanics or cross-toothed connections on request.
The flange bearing’s bell and the connection ring are manufactured from high-quality cast aluminum, while the other metal parts are steel.
The GKN Stromag Periflex® disc tire is manufactured from natural rubber (Nr) or a synthetic rubber in various torsion spring stiffnesses. These allow an adjustment to drives that are susceptible to torsional vibrations.

the GKN Stromag iGe...fG concept The GKN Stromag IGe...FG is a highly flexible rubber coupling with a progressive characteristic (see figure). It is ideal for the transmission of high torques with its particularly compact design and light weight.
The coupling’s external part can be connected directly to a diesel engine’s flywheel or the like. The torque is transmitted to the hub and the cardan shaft via rubber elements arranged in a star pattern. The internal part of the coupling, consisting of the hub and support flange, is radially mounted in the external part of the coupling via the shaft and bushing and fastened in the axial direction using rings.
The radial and axial forces generated by the cardan shaft are absorbed by the coupling and conveyed to the main engine bearing.
The series extends across a nominal torque range from 4000 Nm to 25000 Nm.
The GKN Stromag IGe...FG is manufactured exclusively from metal or high-quality cast parts. They are manufactured from turned parts to ensure that they run smoothly and quietly.
The GKN Stromag IGe...FG coupling is ideal for absorbing large impact torques due to the use of extremely strong rubber elements. large alternating torques are also permitted, as the damping heat is easily discharged via the space between the individual elements.

TKmax1
The coupling’s maximum torque TKmax1
can be endured as a peak load and may not be exceeded by normal, non-stationary peak system torques T

The coupling’s maximum torque TKmax2
can be endured as a rarely occurring peak load and may not be exceeded by normal, non-stationary peak system torques T

CTdyn
The dynamic torsion spring stiffness indicates the ratio of torque amplitude to torsion angle amplitude during an oscillation.
The torque amplitude is superimposed on an initial load (coupling torque). For couplings with a linear characteristic (GKN Stromag Periflex® cS and aFl), the c
Tdyn value over the coupling torque is constant.
However, it changes depending on the amplitude, the frequency and the temperature of the flexible element.The c
Tdyn data relate to a coupling torque of 0.8 • T
KN, an alternating torque of 0.2 • T
KN and a frequency
of 10 Hz for a coupling at operating temperature with a surface temperature of about 50°c.The GKNm Stromag IGe coupling has a progressive characteristic. I.e. the c

The relative damping is a measure of the ability of the coupling to convert part of the vibration energy into heat.
The damping can be determined using the damping loop (hysteresis loop).
The aD surface is a measure of the damping activity WD during a vibration cycle.
The ael surface represents the flexible strain activity Wel during a load.The data relate to a coupling torque of 0.8 • T
