The connecting rod assembly is a core component of the excavator engine, primarily used to connect the piston and crankshaft, converting the reciprocating linear motion of the piston into the rotational motion of the crankshaft, thereby transmitting power. Its structure typically consists of the connecting rod body, connecting rod big end cap, connecting rod small end bushing, connecting rod big end bearing, and connecting rod bolts.
Motion Conversion: Converts the reciprocating motion of the piston into the rotational motion of the crankshaft.
Power Transmission: Withstands the periodic tensile and compressive loads from the combustion chamber pressure, ensuring efficient power transmission.
Structural Support: As part of the engine frame, it bears various loads.
In excavators, the connecting rod assembly is not only used in the engine but also in components such as hydraulic supports. For example, the connecting rods (such as the front connecting rod and the rear connecting rod) in the hydraulic support achieve stable control of the distance between the top beam and the coal wall through a four-bar linkage mechanism, thereby enhancing the support capacity and extending the equipment life.
