ARCUSAFLEX-VSK - Highly-flexible U-joint couplings - Reich Coupling Systems

Drive shafts are 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 drive shafts exhibit some torsional flexibility, the mass of the prime mover and driven machine may induce a resonant system.

If the prime mover is an internal combustion engine, a highly flexible ARCUSAFLEX-VSK U-joint coupling (short form: AC-VSK) is required to protect the drive train from dynamic overload. Highly flexible AC-VSK U-joint 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 U-joint coupling is mounted on the engine flywheel, ahead of the drive train with drive shaft. The AC-VSK U-joint coupling has an axial and radial integral bearing to accommodate the weight of the drive shaft and its reaction forces.
