7.8) Propeller gearbox
Reduction ratio
Reduction ratio
crankshaft: propeller shaft
2.54:1
The propeller shaft is driven by the crankshaft by means of a
spur gear unit.
The power transmission from the crankshaft to the propeller
consists of:
• Overload clutch
• Damper clutch
• Torsion shaft
The damper clutch and torsion shaft absorbs vibrations and/or
shocks caused by engine running and/or the propeller. The
overload clutch protects the crankshaft in case of a propeller
strike.
Governor
Alternatively a hydraulic governor for constant speed propeller
can be used (only for configuration 3). The drive is via the pro-
peller reduction gear.
