Engine Crankshaft
The most important part of the engine. The crankshaft transmits the torque to other engine connecting rods, and it transfers the torque to other engine connecting rods. The crankshaft is subjected to the combined action of centrifugal force of rotating mass, periodic gas inertia force and reciprocating inertia force, which makes the crankshaft bear bending and torsion load. Therefore, the crankshaft should have enough strength and rigidity, and the journal surface should be wear-resistant, work evenly and have good balance.
