Vulkan Rato S Coupling

Torque range
from 12,5 kNm - 800,0 kNm

Applications
Flexibly mounted engines, rigidly mounted engines

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 behaviour of the drive system. The essential parts of the coupling are: the torsional flexible element, the membrane package to absorb the axial displacements and the connecting parts to the drive and driven machinery.
