ARCUSAFLEX-VSK  - Reich Kupplungen

ARCUSAFLEX-VSK

The highly torsionally flexible ACRUSAFLEX-VSK coupling is used in a drive train when a large shaft displacement or an extended distance between the drive and the driven components must be compensated. Depending on the arrangement of the drive train components, a non-uniform motion of the speed may result, and since cardan shafts exhibit some torsion flexibility, the mass of the prime mover and driven machine may induce a resonant system.

Advantages of the highly tosrionally flexible ARCUSAFLEX-VSK couplings:

  • Linear torsional deflection characteristic
  • Elements available in different torsional stiffnesses
  • Enhanced damping capacity through frictional damping
  • Available in 9 sizes: from 390 Nm to 20.000 Nm
  • Maintenance-free coupling bearings
  • Radial bearing close to the cardan joint
  • •A variety of designs for different cardan shaft configurations
  • •Many types with SAE connection dimensions or as specified
  • •Compact construction, the highly flexible element being protected by the housing
  • •Fail-safe device visible from the outside for ease of inspection

Produktdetails

arcusaflex vsk einsatz 250General technical description
If the prime mover is an internal combustion engine, a highly flexible AC-VSK coupling is required to protect the drive train from dynamic overload. Highly flexible AC-VSK couplings are capable of shifting resonant ranges below the lowest operating speed and of reducing resonance-induced vibratory torques under reversed stresses to tolerable levels.

The highly flexible AC-VSK coupling is mounted on the engine flywheel, ahead of the drive train with drive shaft. The AC-VSK coupling contains its own axial and radial bearing to support the weight of the drive shaft and its reaction forces.

Sizes
 
The AC-VSK coupling series is available in nine standard sizes covering a torque range from 390 to 20 000 Nm. REICHKUPPLUNGEN has an extensive programme of couplings to cover nearly every drive confi guration. Customized solutions can be developed and manufactured even in small batches or as prototypes. Calculation programmes are available for coupling selection and sizing. - Please challenge us!

Application of the highly flexible ARCUSAFLEX-VSK couplings 
For use with combustion engines in conjunction with drive shafts for splitter gearboxes, torque converters, ship gearboxes, control gears and pump drives, for example in drives of construction equipment, excavators, cranes, marine propulsion, locomotives, pump installations and dump trucks.

Item Designation Material
1 Coupling flange Ytandard design spheroidal cast iron (GGG 40)
2 Drive shaft connection flange Steel (yield strength min. 360 MPa)
3 Radial bearing Metal or plastic (maintenance-free)

The highly flexible ARCUSAFLEX-VSK couplings of the type AC-VSK ... F2 are specially designed for fitting to flywheels of internal combustion engines. The coupling flanges (1) of the standard design therefore match engine flywheels with SAE connecting dimensions.
The highly flexible coupling element (5), is made of rubber bonded to steel discs and is mounted with an axial preload acting on the thrust bearing (4). The output flange (2), used to connect the cardan shaft is precisely located by means of the thrust bearing (4) and the radial bearing (3) ensuring excellent concentricity. The dynamic performance of the coupling is improved by the pre-loaded rubber element and stabilizing effect of the support bearings providing enhanced damping capacity due to additional frictional damping.
