What is a Crankshaft?

The Crankshaft of an engine is mechanical equipment whose main function is to convert the Linear motion of the Piston to Rotational Motion. The reciprocating motion of the piston is transferred to the crankshaft through Connecting Rod. A crankshaft has crankpins, crank webs, balancing weights, and main journals. The big end of the connecting rod is connected to the crankpin of the crankshaft.
In a 4 stroke engine, one complete rotation of the crankshaft takes place in two strokes of the piston. A crankshaft has the following main parts :
1. Crankpin
2. Main Journals
3. Crank Web
4. Counterweights
5. Thrust Washers
6. Oil passage & Oil Seals
7. Flywheel Mounting Flange
