5.3 Group 3 - Crankshaft, connecting rod and piston
5.3.1 Crankshaft
The crankshaft turns as it gets the power from the pistons. The crankshaft transmits the power to
the attached propeller shaft of the ship.
Main bearings on the two sides of each crank (002, Figure 5-11) hold the crankshaft in position.
The crankshaft gear wheel (005) is part of the thrust bearing.
On the driving end of the crankshaft there is a flywheel (004). This flywheel decreases the pulsation
from the cylinders.
The length of the crankshaft is related to the number of cylinders.
