Description

Complementary to the "all-round" RATO-S coupling the highly flexible RATO-R coupling has been specially designed for use in installations requiring a high level of torsional flexibility and misalignment capacity. Inherent features of the design include the high dynamic load capacity and good rotational dynamic properties due to the low rotating inertias. The area of application is primarily in high-speed main/PTO systems driven by a Diesel engine or electric motor. In the low to middle torque range where the handling and installation of a complete element is practibable the RATO-R coupling is an additional alternative. A good tuning of the systems´s torsional vibration characteristics is possible due to the variety of torsional stiffnesses and element configurations available. The radial, axial and angular flexibility of the RATO-R coupling, with the shortest possible installation length, enables good compensation of shaft misalignments due to the flexible mounting of the prime mover, foundation movements etc. to be achieved. The use of relatively soft annular membranes permits, in the event of an axial vibration excitation, an efficient isolation of the system-effectively protecting shaft bearings. By avoiding noise paths, direct metal to metal contact, the RATO-R has excellent noise-attenuation properties.
