hajtókarokkal

Hajtókarokkal, often translated as connecting rods, are essential components in reciprocating internal combustion engines and steam engines. Their primary function is to convert the linear motion of a piston into the rotational motion of a crankshaft. This conversion is crucial for the engine's operation, allowing it to generate power through the cyclical movement of its parts.

A hajtókar typically consists of a shaft with two ends. One end, known as the small end or piston pin end, is connected to the piston via a piston pin (or gudgeon pin). The other end, the big end, is attached to an offset journal on the crankshaft. This offset connection allows the linear up-and-down motion of the piston to be translated into the circular motion of the crankshaft as it rotates.

The design and material of hajtókarokkal are critical for engine performance and durability. They must be strong enough to withstand significant tensile and compressive forces during each engine cycle. Common materials include forged steel, powdered metal, and sometimes aluminum alloys in lighter applications. The balance and precision manufacturing of these components are also vital to minimize vibrations and ensure smooth engine operation. Failure of a hajtókar can lead to catastrophic engine damage.
