Vulkan RATO DS

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. RATO DS

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 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

Torque range

from 6.3 kNm up to 160.0 kNm

Applications

Rigidly mounted engines
