Description
The
highly-flexible RATO-S coupling is a torsionally flexible rubber
coupling that compensates radial, axial and angular shaft
displacements of the connected machinery. The torque is
transmitted by elements loaded in shear. The different torsional
stiffnesses and damping factors available provide the possibility
to satisfactorily tune the torsional vibration behavior of the
drive system. The essential parts of the coupling are: the
torsionally flexible part, the membrane part and the connecting
parts. The torsionally flexible part consists of elements, which
can be arranged in one row or more rows respectively, dependent on
the coupling size and the stiffness level. The flexible elements
are divided into several segments. Due to the element segments and
in the case of multi-row couplings, a displaced arrangement of the
segments gives a good ventilation and cooling of the elements.
With certain sizes the segments have additional ventilation holes.
The segmental construction also assures easy handling at
installation.
