Flexible mechanical coupling RATO DS/DS+

for shipsfor shafts

The highly flexible RATO DS and RATO DS+ couplings has been specially designed for use in installations requiring a high level of torsional flexibility and medium level of misalignment capacity. Supplementing the all-round couplings RATO S and RATO S+. The RATO DS / RATO DS+ couplings has been developed to offer an application-orientated coupling design. Specially for rigidly mounted ship´s main propulsion. The available stiffnesses enable a good tuning of the system with respect to both the transient and steady-state torsional vibration response. In the tradition of VULKAN Couplings, a backlash-free torque transmission is achieved. Benefits High-performance elastomer of the ACOTEC sizes allows the use of a smaller size and thus offers a commercial benefit. It is possible to provide a safety device against racing to protect the drive system Maximum flexibility for the solution and a range of special design The element design delivers torque transmission without any play. Optimal heat dissipation ensures functionality and availability of the drive system even under the harshest conditions The compact dimensions of the coupling ensure considerable weight reduction and therefore greater efficiency in the drive as well as lower project costs Technical Data Torque Range TKN [kNm] 6.3 kNm - 160 kNm Speed range [1/min] 1040 RPM - 2100 RPM (Area of) Applications Rigidly mounted engines
