Flexible mechanical coupling RATO R/R+

for shipsfor shafts

Complementary to the all-round couplings RATO S and RATO S+ the highly flexible couplings RATO R and RATO R+ 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 practicable the couplings RATO R and RATO R+ are an additional alternative. With the introduction of the ACOTEC range, smaller sizes with higher power density provide good price/ performance ratio.. Benefits Various torsional rigidities and element designs ensure excellent coordination of the torsional vibration and therefore availability of the drive system With low rotating masses, it is optimised for the trend towards high-performance and high-speed engines Maximum flexibility in providing a solution considering that it can be easily integrated in different systems Soft circular diaphragms provide effective protection for the shaft bearing with axial vibration decoupling Excellent noise damping characteristics by avoiding direct metallic contact Technical Data Torque Range TKN [kNm] 12.5 kNm - 530 kNm Speed range [1/min] 710 RPM - 2750 RPM (Area of) Applications Flexibly mounted engines, rigidly mounted engines
