General Technical Description
Drive shafts are used in adrive train when a large shaft displacement or an extended distance between thedrive and the driven components must be compensated. Depending on thearrangement of the drive train components, a non-uniform motion of the speedmay result, and since drive shafts exhibit some torsional flexibility, the massof the prime mover and driven machine may induce a resonant system.
If theprime mover is an internal combustion engine, a highly flexible ARCUSAFLEX-VSKU-joint coupling (short form: AC-VSK) is required to protect the drive trainfrom dynamic overload. Highly flexible AC-VSK U-joint couplings are capable ofshifting resonant ranges below the lowest operating speed and of reducingresonance-induced vibratory torques under reversed stresses to tolerablelevels.
Thehighly 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 anaxial and radial integral bearing to accommodate the weight of the drive shaftand its reaction forces.
TheAC-VSK coupling series is available in nine standard sizes covering a torquerange from 390 Nm to 20 000 Nm. REICH have an extensive range of couplings tocover nearly every drive configuration. Customized solutions can be developedand manufactured even in small batches or as prototypes. In additioncalculation programs are available for all necessary dimensioning.
Applicationof the highly flexible ARCUSAFLEX-VSK U-joint couplings
For usewith combustion engines in conjunction with drive shafts for splittergearboxes, torque converters, ship gearboxes, control gears and pump drives,for example in drives of construction equipment, excavators, cranes, marinepropulsion, locomotives, pump installations and dump trucks.
