Crankshafts Types
1, Cast Iron Crankshaft: the cast iron crankshaft is manufactured through the casting process and are commonly used in diesel engines due to their cost-effectiveness. Heat treatment is often applied to boost tensile strength and hardness, thereby extending the crankshaft's lifespan. The manufacturing process for cast crankshafts is relatively straightforward, making them a popular choice for various engine applications.
2, Forged Crankshaft: the forged crankshaft is manufactured through a forging process, wherein a single block of metal is heated and shaped using various forces to attain the desired form. This method eliminates the need for welding or heat shrinking to assemble different parts. These crankshafts are well-suited for moderate-speed engines like generators but may require additional hardening processes to enhance rigidity.
Crankshaft Structure
The crankshaft assembly is composed of the following part,
1, Main Journal Bearings: The main journal bearings serve as the central axis of the crankshaft, playing a fundamental role in its structure and function.
2, Counterweights: Counterweights are critical components of the crankshaft, ensuring smooth operation. They are attached to the crankshaft using rod-bearing journals, forming pairs of counterweights.
3, Flywheel Flange: The flywheel of a vehicle is securely fastened to the crankshaft via a component known as the flywheel flange. This connection is vital because the flywheel is a substantial mechanical device that rotates at high RPM. The flywheel flange, located at one end of the crankshaft, is meticulously designed to rigidly hold the flywheel in place, ensuring its stability during operation.
4, Pulley End: At the opposite end of the crankshaft, the pulley end is attached to the engine, and it can also connect to the gearbox, serving as a critical link in power transmission within the vehicle's system.
5, Balance Weight: Balance weights are additional elements within the counterweights to enhance the stability and balance of the crankshaft, contributing to the engine's overall performance.
6, Rod Bearing Journals: Rod bearing journals serve as connectors between the pistons and the crankshaft. These journals play a vital role in the engine's operation, as they facilitate the attachment of pistons to the crankshaft using pins.
7, Oil Passage: The oil passage is a conduit that links the main journal bearing to the rod journal bearing. This passage is essential for the lubrication of the crankshaft, as it enables the flow of oil from the main journal bearing to the rod journal bearing, ensuring the smooth and friction-free operation of the engine's moving parts.
Functions of Crankshaft
The crankshaft plays a pivotal role in the engine's operation, serving numerous essential functions:
1, It converts the linear motion generated by the engine into rotational motion.
2, Crankshafts control the precise amount of oil necessary for lubricating the engine.
3, The crankshafts deliver power to the piston as needed, achieved through the downward movement of counterweights. As a result, the crankshaft guarantees the seamless operation of an internal combustion engine.
