The main function of excavator connecting rod bearings is to reduce wear, connect components, provide support, and transmit power. The connecting rod bearing is installed at the connection between the connecting rod and the crankshaft, ensuring smooth and durable engine operation by reducing friction and wear.
Specifically, the connecting rod bearing is made of high wear-resistant and high-strength alloy material, with a semi-circular shape and a thin lubricating oil film covering the inner surface to reduce friction and wear. Its main functions include:
Reduce wear: The design and use of connecting rod bearings can effectively reduce wear between the connecting rod journal and crankshaft, extending the service life of the engine.
Connecting component: It connects the connecting rod with the crankshaft to ensure smooth power transmission.
Provide support: The connecting rod bearing provides necessary support during high-speed operation to ensure stable engine operation.
Power transmission: Convert the reciprocating motion of the piston into the rotational motion of the crankshaft to achieve the power output of the engine.
In addition, the structural design of the connecting rod bearing also plays an important role. It includes upper and lower connecting rod bearings, with oil grooves and oil holes set along the circumference of the inner cylindrical surface to ensure the circulation of lubricating oil and further reduce friction and wear.
