The main rotating parts of the air compressor crankshaft engine, after installing the connecting rod, can accept the up and down (reciprocating) movement of the connecting rod into a cyclic (rotating) movement.
The air compressor crankshaft is an important part of the engine. Its material is made of carbon structural steel or nodular cast iron. There are two important parts: the main shaft journal, the connecting rod journal, and others. The main journal is installed on the cylinder body, the connecting rod neck is connected with the large end hole of the connecting rod, and the small end hole of the connecting rod is connected with the cylinder piston, which is a typical crank slider mechanism.
The lubrication of the crankshaft mainly refers to the lubrication of the bearing bush between the rocker arm and the lubrication of the fixed points at both ends. This is generally pressure lubricated. There will be an oil passage in the middle of the crankshaft to communicate with each bearing pad. After the engine is running, the oil pump provides pressure to supply oil for lubrication and cooling.
The working process of the engine is that the piston explodes through the mixed compressed gas and pushes the piston to make a linear movement, and transmits the force to the crankshaft through the connecting rod. The rotation of the crankshaft is the power source of the engine. It is also the source of power for the entire mechanical system.
Piston air compressor is a kind of reciprocating air compressor. Its compression element is a piston, which reciprocates inside the cylinder and presses the same gas as the piston. Derivative products include air compressors, assembly line equipment, plastic machines, fans, etc.
