The crankshaft is the power center of the engine, which converts the reciprocating motion of the piston connecting rod into rotational power output and drives the camshaft. High strength materials are required to resist fatigue, precision machining to reduce vibration, and ensure stable force transmission.
The core of the engine crankshaft is to convert power, convert the reciprocating motion of the piston into rotational force, and also drive accessories. High rigidity and impact resistance are required in terms of quality, with a wear-resistant surface and strict precision control to prevent vibration.
