[0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod, converts it into torque and outputs it through the crankshaft to drive other accessories on the engine to work. The crankshaft is jointly affected by the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, so that the crankshaft bears the action of bending and torsional loads. Therefore, the crankshaft is required to have sufficient strength and stiffness, and the journal surface needs to be wear-resistant, work evenly and have good balance.
