Mechanical Features and Designs

A crankshaft is a mechanical device that transforms piston-driven reciprocating motion into rotation. It is the recipient of force that is created by gas compression and pistons.

Pistons apply a thrusting movement into a cylindrical rod, establishing a force created by compressed gas that is transferred to the crankshaft by continuous rotary motion. The result amounts to the pistons turning the crank and transforming combustion into torque, which gives cars and engines the ability to move.

[edit] History

The first crankshafts were developed in the 15th century and were cranked by hand. Rods were later incorporated into the crank to make the process easier. Although considered a significant invention and a turn towards a mechanized society, the importance of the crankshaft was not immediately felt.[1]

The successfully built crankshaft led the way to for the invention of the steam engine. Steam engines were made functional with boiling water that created steam, which expanded and pushed the pistons turning the crankshaft, a process that moved the wheels of the first automobile. Nicholas Joseph Cugnot, was the first person to successfully create this configuration, leading to the eventual automobile revolution.[2]

The use of steam engines in the 18th century provided a solution for farmers and construction workers who were looking for ways to ease the amount of hard work that was normally endured by hand and animals. Rollers and excavators, first powered by steam engines, made their way into the industry, forever changing it.
