The crankshaft is the most important component in the engine. It takes the force from the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine. The crankshaft is subjected to a centrifugal force of a rotating mass, a cyclically varying gas inertial force, and a reciprocating inertial force to cause the crankshaft to undergo a bending torsional load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance.
