A crankshaft is a shaft driven by a crank mechanism consisting of a series of cranks and crank pins to which the connecting rods of an engine are attached. [1] It is a mechanical part that can convert between reciprocating and rotational motion. In a reciprocating engine, it converts the reciprocating motion of the piston into rotational motion, while in a reciprocating compressor, it converts the rotational motion into reciprocating motion. To convert between the two motions, the crankshaft has "crank shots" or "crank pins" [explanation needed], additional bearing surfaces whose axis is offset from the crank axis, to which the "big ends" of the connecting rods are from each cylinder connection.

It is typically coupled to a flywheel to reduce the vibration characteristic of the four-stroke cycle, and sometimes to a torsional or vibration damper at the opposite end to reduce torsional vibrations caused by the farthest cylinders along the length of the crankshaft. output end that affects the torsional flexibility of the metal.

A crank in the form of an eccentrically mounted lever of a rotary hand mill originated in Celtiberian Spain in the 5th century BC and eventually spread throughout the Roman Empire. [8] [2] [3] A Roman iron column dating to the 2nd century AD was excavated in Augusta Raurica, Switzerland. [9] [10] The Roman crank-operated mill is dated to the end of the 2nd century. 

Hierapolis sawmill (3rd century) in Asia Minor, a machine combining a crank and a connecting rod. 
Evidence of a crank coupled with a connecting rod is seen at the Hierapolis mill dating to the 3rd century BC; They are also found in stone sawmills in Roman Syria and Ephesus, which date to the 6th century BC. [12] A waterwheel is seen on the pediment of the Hierapolis mill, fed by a mill bed powered by two frame saws that cut the blocks through a kind of connecting rod and crank. [13] The crank and connecting rod mechanisms of the other two archaeologically attested sawmills worked without gearing. The poet Ausonius, who lived in the late 4th century, from the water-powered marble saws in Germany; at about the same time, these mill types seem to have been pointed out by Gregory of Nyssa from Anatolia.
