wholesale factory price steel crankshafts for cars

Short Description:

The crankshaft is a key component in an internal combustion engine, converting the reciprocating motion of the pistons into rotational motion that drives the car’s engine. The crankshaft is typically made from high-strength alloy steel, capable of withstanding the high-speed rotation and high-pressure working environment.
The main components of the crankshaft include:
1. Crankpins (crankpin): Connect the connecting rods with the main journal of the crankshaft.
2. Main journals (main journals): Located at the center of the crankshaft, used to support the crankshaft and transfer the rotational force to the flywheel.
3. Main bearings (main bearings): Used to support the main journals, reducing friction and wear.
4. Crankpin journals (crankpin journals): Connect the connecting rods with the crankpins.
5. Crankpin bearings (crankpin bearings): Used to support the crankpins, reducing friction and wear.
The working principle of the crankshaft: When the pistons move up and down in the cylinders, the connecting rods rotate around the crankpins. As the crankshaft rotates, the main journals are connected to the flywheel, converting the reciprocating motion of the pistons into rotational motion.
The crankshaft plays a crucial role in the car’s engine, responsible for transmitting the power generated by the engine and ensuring the smooth and reliable output of power. Therefore, the quality and performance of the crankshaft directly affect the overall performance and lifespan of the engine.
