Power Transmission

16.1 Flexible coupling
The power transmission of propulsion engines is accomplished through a flexible coupling or
a combined flexible coupling and clutch mounted on the flywheel. The crankshaft is equipped
with an additional shield bearing at the flywheel end. Therefore also a rather heavy coupling
can be mounted on the flywheel without intermediate bearings.
The type of flexible coupling to be used has to be decided separately in each case on the
basis of the torsional vibration calculations.
In case of two bearing type generator installations a flexible coupling between the engine and
the generator is required.
