What is a Crankshaft?

A crankshaft is a crucial component in internal combustion engines. It serves as the central rotating shaft responsible for converting the reciprocating motion of pistons into rotational motion, which ultimately drives the vehicle’s wheels or powers machinery.

The crankshaft contains one or more crankpins, which are driven by the pistons via connecting rods. These connecting rods transfer the up-and-down motion of each piston to the crankshaft, allowing it to rotate within the engine block.

Additionally, a flywheel is often attached to one end of the crankshaft to smoothen power delivery and reduce vibration.
