New Flexible Driveshaft Couplings from Centa

Designed by Centa Transmissions for installation between the engine reduction gear and propeller shaft, both types have a flexible element which eliminates shaft-transmitted vibration and noise. They incorporate insulated, self-adjusting, hull-mounted, double-acting bearings which transfer propeller thrust directly to the vessel instead of through the reduction gearbox/engine mounts.

The coupling are able to operate in-line or to accommodate angular misalignment and movement up to 6º for the AGM and 3º for the ADM, making the need for accurate, maintained engine alignment unnecessary and, in the absence of propeller thrust, allowing the use of highly flexible engine mounts and long propeller shafts.

Additionally, a torsional deflection of up to 16º is permissible and consequently torsional stress and shock loads from disturbed water or collision with underwater debris are minimised. The couplings are failsafe and resistant to diesel/lube oil/ seawater bilge mixture. Flange adapters are available for most gearboxes in recent and current production and the couplings will handle torque capacities up to 15,000Nm.
