General Technical Description
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.
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.
