The crankshaft is the most important component in the engine. It bears the force transmitted by connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories in the engine to work. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic gas inertia force, and reciprocating inertia force, making it capable of withstanding bending and torsional loads. Therefore, it is required that the crankshaft has sufficient strength and stiffness, and the surface of journal should be wear-resistant, work evenly, and have good balance.

The crankshaft journal is often made hollow in order to reduce the mass of the crankshaft and the centrifugal force generated during movement. There are oil holes on the surface of each journal to introduce or remove oil for lubrication of the journal surface. To decrease stress concentration, the joints of the main journal, crank pin and arm are connected by transition circular arcs.
