Main Moving Parts of Excavator Engine Parts

The engine provides the power source for the excavator and is the core component of the excavator. The main moving parts of the excavator are crankshaft, connecting rod, piston, piston ring, flywheel, pulley and so on, this article will give you a detailed introduction.

Crankshaft: the reciprocating motion of the piston in the cylinder through the connecting rod into a rotary motion; its main journal mounted on the main bearings of the cylinder block, the crankshaft has a lubricating oil channel inside the crankshaft, so that the lubrication of the main neck of the oil through the oil flow into the connecting rod journals crankshaft with chromium, molybdenum and other elements of high carbon steel, die forging, high-frequency quenching and processing.

Connecting rod: The connecting rod is an important part connecting the piston with the crankshaft, which converts the reciprocating motion of the piston into the rotating motion of the crankshaft. One end of the connecting rod is connected to the piston through the piston pin, and the other end is connected to the crankshaft through the connecting rod bearing. When the piston moves up and down, the connecting rod converts the linear motion of the piston into the rotary motion of the crankshaft through its own oscillation, thus outputting power.

Flywheel: An inertia wheel mounted on the rear end of the crankshaft, which reduces losses in crankshaft rotation by its moment of inertia. It is used to store and balance the fluctuation of rotational power generated by the engine to make the engine run more smoothly.

Piston: the fuel combustion in the cylinder heat energy into the piston up and down movement of mechanical energy, through the connecting rod to make the crankshaft rotation between the piston and the cylinder liner should leave a clearance. Piston is the engine will be the chemical energy generated by the combustion of fuel into mechanical energy of the key components. It is made of high-strength aluminum alloy and can withstand high temperature and pressure working environment. The piston moves back and forth in the cylinder, pushed by the high-temperature, high-pressure gas produced by combustion, which in turn drives the crankshaft to rotate. The movement of the piston includes the intake stroke, compression stroke, work stroke and exhaust stroke, which together form a complete working cycle.

Piston ring: to prevent high-pressure gas in the cylinder from running away from the gap; two gas rings one oil ring oil ring to scrape off the oil adhering to the cylinder wall and maintain a proper oil film.

The main moving parts of the excavator engine collaborate with each other and work together to ensure the efficient and stable operation of the engine. The cylinder provides space for the combustion of fuel, the piston converts the chemical energy of the fuel into mechanical energy, the connecting rod converts the reciprocating motion of the piston into the rotating motion of the crankshaft, and the crankshaft outputs the power to other components. The precise design and cooperative work of these main moving parts provide powerful power support for excavators and meet the needs of modern engineering construction. With the continuous progress of technology, the main moving parts of the excavator engine are also being innovated and optimized to meet the needs of more efficient and environmentally friendly construction. In the future, excavator engines will continue to develop in the direction of electrification, automation and intelligence to achieve higher performance, lower energy consumption and smarter operating experience.

Engine is the power source of excavator, it is the premise and guarantee for the normal work of excavator, if there is a failure, it needs to be repaired or replaced in time.
