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. The AC-VSK coupling series is available in nine standard sizes covering a torque range from 390 Nm to 20 000 Nm. REICH have an extensive range of couplings to cover nearly every drive configuration. Customized solutions can be developed and manufactured even in small batches or as prototypes. In addition calculation programs are available for all necessary dimensioning. Application of the highly flexible ARCUSAFLEX-VSK U-joint 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.
