17.1 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 tor-
sional vibration calculations.
In case of two bearing type generator installations a flexible coupling between the engine and the generator
is required.
