A chainsaw consists of several parts:
1. Engine - almost always a two-stroke gasoline (petrol) engine, usually 30-120 cc cylinder volume or motor.
2. Drive mechanism - usually a centrifugal clutch and the sprocket.
Guide rod - wear-resistant alloy steel is usually 40-90 centimeters (16-36 inches) long long round ends. A side guide groove cutting chain. Professional cycling-style bar, called the bow stem, is also used at the same time, bucking logs and cleared brush, although they are now rarely encountered due to the increased risk of surgery.
3. Cutting chain - usually in each such segment (which is similar to a bicycle chain from riveted metal sections composed, but no roll) with a small sharp cutting teeth. Each tooth form folded labels need chromium plated steel with sharp corners or curved corners and two cutting edges, one at the top plate and a side plate. Teeth alternately left and right chain. Chain in a different pitch and meter; a chain pitch is defined as any three consecutive rivets (for example, 8 mm, 0.325 inches) across half the length, and the meter is that it fits into the guide bar drive linkage thickness (e.g., 1.5 mm, 0.05 inches). Traditional "full" chain link having two drivers each tooth. "Skip" link in the chain drive every three teeth. Built to ride in front of each tooth is teeth and limit the depth of cut, typically to about 0.5 mm (0.025 ") depth gauge is safe operation of critical chain depth gauge or" rake ", if the left is too high they will result in very slow cutting after that, if filed too low chain will become more prone to return to the lowest depth gauge will also lead to the saw excessive vibration. vibration is not only uncomfortable for the operator, but also detrimental to the saw.
4. Tensioning mechanism - some way to adjust the tension in the cutting chain, so that it is neither binding nor loose from the guide bar.
The lower side of each link has referred to as "the drive link", which is located in a small metal finger chain of the bar to help carry around the rod lubricating oil, and the inner body of the saw chain drive engine gear engagement. The engine through a centrifugal clutch in the vicinity of the track of the chain drive, the chain under power engagement engine speed increases, but it is allowed to stop with the engine speed slows to idle speed.
Significantly improved since chainsaw safety equipment and overall design have taken place, the invention of the chainsaw, saving many lives and preventing countless serious injuries. These include chainbrake system, better chain design and anti-vibration systems. With chainsaw carving has become more popular, chainsaw carving manufacturers are making very short, narrow tip of the bar. These are called "down season", "nickel-down" or "tipped the iceberg" on the basis of the rod, round tip size. Echo chainsaw manufacturer sponsored the carving series, and engraving such as the former singer Qie Like fled inside. As the number of chainsaw RedMAX G3200 CV is designed for carving build applications.
