ARCUSAFLEX-VSK General Technical Description ARCUSAFLEX-VSK Highly-flexible U-joint coupling Drive shafts are used in a drive train when a large shaft The AC-VSK coupling series is available in nine standard sizes displacement or an extended distance between the drive and covering a torque range from 390 Nm to 20 000 Nm. REICH the driven components must be compensated. Depending on have an extensive range of couplings to cover nearly every drive the arrangement of the drive train components, a non-uniform configuration. Customized solutions can be developed and motion of the speed may...

ARCUSAFLEX-VSK Nominal torques from 390 Nm to 20 000 Nm ARCUSAFLEX-VSK Advantages The most important attributes and advantages of the highly flexible ARCUSAFLEX-VSK coupling are: ➜ Linear torsional deflection characteristic ➜ Elements available in different torsional stiffnesses ➜ Enhanced damping capacity through frictional damping ➜ Maintenance-free coupling bearings ➜ Radial bearing close to the cardan joint ➜ A variety of designs for different drive shaft configurations ➜ Many types with SAE connection dimensions or as specified ➜ Compact construction, the highly flexible element being...

Coupling Information ARCUSAFLEX-VSK Technical Layout The highly flexible ARCUSAFLEX-VSK U-joint couplings of type bearing (4). The output side drive shaft flange (2), used to connect AC-VSK F2 are specially designed for fitting to flywheels of internal the drive shaft is precisely located by means of the radial bearing combustion engines. The coupling flanges (1) of the standard type (3) ensuring excellent concentricity. therefore match engine flywheels with SAE connecting dimensions. The pre-loaded rubber element improves the dynamic performance The highly flexible coupling element (5),...

Coupling Information ARCUSAFLEX-VSK General Technical Data Standard Type Coupling size Element version Nominal torque Maximum torque Continuous fatigue torque Permissible power loss Dynamic torsional stiffness Maximum speed 1) The relative damping relates only to the elastomer. The frictional damping of the bearings has to be considered separately, depending on the type of operation Shore hardness ShA, Resonance factor VR and relative damping Ψ Sh A measurable rubber hardness is subject to a variation that is defined as ± 5° Shore A according to DIN 53505. However, this variation is...

Coupling Information ARCUSAFLEX-VSK Selection of the Coupling Size The selected coupling for internal combustion engine drives should be verified by a torsional vibration analysis which we will provide on request. A preliminary selection of the coupling can, however, be made based on the continuous engine power being transmitted. In selecting the coupling size the following should be satisfied: The nominal torque of the coupling TKN must be taken into account at every temperature and operating load of the coupling, whilst observing the service factors S (e.g: temperature factor St) shall be...
