Description

Applications Rigidly mounted engines The highly flexible RATO DS coupling 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 RATO S. The RATO DS has been developed to offer an application - orientated coupling design. Specially for rigidly mounted ship´s main propulsion. The 3 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. When required a torque limiting device can be fitted. Benefits - The element design delivers toque 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
