hajtócsapágy

Hajtócsapágy translates to connecting rod bearing in English. It is a critical component in internal combustion engines and other reciprocating machinery. The primary function of a hajtócsapágy is to facilitate the rotational motion of the crankshaft by connecting it to the piston rod (connecting rod).

These bearings are typically split into two halves, forming a shell that encases the crankshaft journal. This design allows for installation and removal without disassembling the entire crankshaft. The hajtócsapágy is responsible for supporting the immense forces generated during the combustion cycle and converting the linear motion of the piston into the rotary motion of the crankshaft.

The hajtócsapágy consists of a bearing shell, often made from a combination of metals like steel, bronze, and Babbitt metal. The Babbitt layer provides a low-friction surface that allows for smooth rotation. Lubrication is essential for the proper functioning of hajtócsapágy. A constant supply of oil is pumped to the bearing surfaces to reduce friction, dissipate heat, and prevent wear.

Wear and tear on hajtócsapágy can lead to significant engine damage, often manifesting as knocking or rattling noises. Regular maintenance and proper oil changes are crucial to ensure the longevity of these vital engine parts. Failure of a hajtócsapágy can result in catastrophic engine failure.
