The role of the crankshaft
Release time:
2025-03-24
The crankshaft balances periodically changing inertial forces (such as gas pressure and piston reciprocating inertial forces) through the flywheel assembly to reduce vibration; at the same time, it stores kinetic energy to overcome the resistance of non-work strokes (such as compression strokes) to ensure the smooth operation of the engine.
The core function of the crankshaft is to convert the reciprocating movement of the piston into a rotating movement and output power, while balancing the engine operation and storing
energy.
Specific action analysis
Energy Conversion and Power Output
The crankshaft receives the reciprocating force of the piston through the connecting rod, converts it into rotating motion and outputs torque, providing power to the engine and other
auxiliary equipment (such as generators, water pumps, etc.). For example, in a four-stroke engine, the crankshaft converts linear thrust generated by the combustion stroke into continuous
rotational power.
Balanced operation and energy storage
The crankshaft balances periodically changing inertial forces (such as gas pressure and piston reciprocating inertial forces) through the flywheel assembly to reduce vibration; at the same time,
it stores kinetic energy to overcome the resistance of non-work strokes (such as compression strokes) to ensure the smooth operation of the engine.
Drive other systems
The power output from the crankshaft is not only used for vehicle driving, but also drives auxiliary equipment through belts or gears, such as air conditioning compressors, oil pumps, etc.
Related extensions
The design of the crankshaft requires both strength and wear resistance. Its key components such as the main shaft journal (with pressure) and the connecting rod neck (connecting rod)
directly affect the engine performance.
