Krankiakseli

Krankiakseli, commonly known in English as a crankshaft, is a vital component in internal combustion engines. Its primary function is to convert the reciprocating linear motion of the pistons into the rotational motion required to power a vehicle or other machinery. The crankshaft is essentially a shaft with several offset sections called crank throws, to which the connecting rods are attached. As the pistons move up and down within their cylinders, they push on the connecting rods. These rods, in turn, pivot on the crank throws, causing the crankshaft to rotate. The design of the crankshaft is critical for engine balance and smooth operation. Counterweights are often incorporated into the crankshaft design to offset the forces generated by the moving pistons and connecting rods, thereby minimizing vibration. The crankshaft is typically made from strong materials like forged steel or cast iron to withstand the immense pressures and stresses it endures during the engine's operation. Its rotation is the direct output that is usually transmitted through the drivetrain to the wheels.
