How does a crankshaft work?
The crankshaft is the most important component of the engine. It takes the force from the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is affected by the centrifugal force of the rotating mass, the periodically changing gas inertia force and the reciprocating inertia force, causing the crankshaft to be subjected to 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.
