The crankshaft is a rotating shaft driven by a crank mechanism. It is a mechanical unit that facilitates the transformation of the piston’s linear movement into a rotating motion.
A crankshaft is an important part of an engine’s power transmission system. Located within the engine crankshaft block, it uses a connecting rod to convert the reciprocating motion of the pistons into a rotating one. This rotary motion generated by the crankshaft moves the flywheel and the vehicle wheels.
