väntvõllist

Väntvõll is an Estonian term referring to a crankshaft. It is a crucial component in internal combustion engines, converting the reciprocating linear motion of pistons into rotational motion. This rotational motion is then transmitted to the drivetrain, ultimately powering the vehicle or machinery.

The basic design of a väntvõll consists of one or more crank throws, which are offset journals to which the connecting rods are attached. Pistons are connected to the crank throws via connecting rods. As the piston moves up and down within the cylinder, the connecting rod pushes and pulls on the crank throw, causing the väntvõll to rotate.

Väntvõllid are typically made from strong forged steel or cast iron to withstand the high stresses and temperatures they encounter during operation. The design and balancing of the väntvõll are critical for engine smoothness and longevity. Imbalances can lead to vibrations and premature wear.

The number and arrangement of crank throws depend on the engine's configuration, such as inline, V-engine, or opposed cylinder designs. Lubrication is essential for the proper functioning of the väntvõll, with oil supplied to bearings that support its rotation. Wear on these bearings can significantly impact engine performance and lifespan.
