Take you up knowledge! Gas Chainsaw logging saw structure


Structure of Gas Chainsaw
As a whole system, Gas Chainsaw is divided into ignition system, oil supply system, inlet and exhaust system, lubrication system, cooling system, starting system, etc.
The cylinder is the core component of the Gas Chainsaw, including the inner wall, heat sink, combustion chamber, etc. there are three holes on the cylinder, namely inlet hole, exhaust hole and exchange hole, which are closed by the piston at a certain time. The complete sealing of the cylinder is a necessary condition for the continuous operation and power generation of the Gas Chainsaw. The cylinder is mounted on the crankcase. The piston can move back and forth in the cylinder and close the cylinder from the lower part of the cylinder to form a sealing space. The fuel burns in the sealed space and the generated power pushes the piston to move. The reciprocating motion of the piston pushes the crankshaft for rotary motion through the connecting rod, and the crankshaft outputs power from the flywheel end.
The crank connecting rod mechanism is composed of piston group, connecting rod, crankshaft and flywheel. It is the main part of Gas Chainsaw to transmit power.
The piston group is composed of piston, piston ring, piston pin, etc. The piston is cylindrical and equipped with a piston ring to seal the cylinder when the piston moves back and forth and prevent gas leakage in the cylinder. The piston pin is cylindrical, which penetrates into the pin hole on the piston and the small end of the connecting rod to connect the piston and the connecting rod.
The connecting rod is divided into three parts: big end, small end and rod body. The big end is connected with the crank pin of the crankshaft, and the small end is connected with the piston pin. When the connecting rod works, the small end moves back and forth with the piston, the large end rotates around the crankshaft axis with the crank pin, and the rod body makes a complex swing motion.
The function of the crankshaft is to convert the reciprocating motion of the piston into rotary motion, and transfer the work done by the expansion stroke through the flywheel installed on the rear end of the crankshaft. The flywheel can store energy, make other strokes of the piston work normally, and make the crankshaft rotate evenly.
The intake and exhaust system is usually composed of air filter, intake pipe, exhaust pipe and muffler.
In order to supply fuel to the cylinder, the Gas Chainsaw is equipped with an oil supply system. The air and fuel are mixed at a certain concentration through the carburetor installed at the inlet end of the intake pipe, and then supplied to the cylinder through the intake pipe. The electric spark controlled by the Gas Chainsaw ignition system is ignited regularly.
When the fuel in the Gas Chainsaw cylinder is burned, the piston, cylinder and other parts are heated and the temperature rises. In order to ensure the normal operation of the Gas Chainsaw and prevent the piston, cylinder and other parts from being damaged due to overheating, a cooling system must be provided. The flywheel blade and the wind channel formed by the starter cover, shell and other parts form the cooling system of the Gas Chainsaw.
The Gas Chainsaw cannot automatically turn into operation from the parking state. The crankshaft must be turned by external force to start it. This device generating external force is called starting device.
