Soundown Component
RD Flexible Shaft Couplings
Flexible couplings between propeller shaft and gearbox that compensate for soft-mounted engine motion and eliminate gear whine.
Description
RD Flexible Shaft Couplings provide a flexible connection between propeller shaft and gearbox, compensating for the motion of soft-mounted engines and reducing gear whine. With no metal-to-metal contact between gear and shaft, they help keep drive line noise out of the hull.
Key features
- Spool machined to mate with the gear flange, plus aluminum element and shaft hub
- Pre-compressed rubber blocks make the coupling flexible radially
- Stiffer isolation rings at the center give the axial stiffness to transmit propeller thrust
- Version without thrust elements for remote thrust bearings, water jets or Z drives
- Twin and Single versions
Applications
- Vessels with aft cabins, V drives, or aft salon bulkheads close to the engine room
