The chainsaw chain is a chain used to transmit mechanical power and is widely used in household, industrial and agricultural machinery, including conveyors, plotters, printing machines, automobiles, motorcycles, and bicycles. It is linked by a series of short cylindrical rollers and is driven by a gear called a sprocket. This is a simple, reliable and efficient power transmission device. The sprocket should not swing and skew when installed on the shaft. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the sprocket is more than 0.5 meters, the deviation can be 2 mm. However, there must be no friction on the side surfaces of the sprocket teeth. If the two wheels offset too much, it will easily cause chain disconnection and accelerated wear. When replacing the sprocket, you must pay attention to check and adjust the offset.

The tightness of the chainsaw chain should be appropriate. Too tight will increase power consumption and the bearings are easy to wear; too loose the sprocket is easy to jump and fall off the chain. The tightness of the sprocket is as follows: lifted or pressed down from the middle of the sprocket, the center distance between the two sprocket is about 2%-3%. The sprocket should not swing and skew when installed on the shaft. In the same transmission assembly, the end faces of the two sprockets should be in the same plane. When the center distance of the sprocket is less than 0.5 meters, the deviation can be 1 mm; when the center distance of the sprocket is more than 0.5 meters, the deviation can be 2 mm. However, there must be no friction on the side surfaces of the sprocket teeth. If the two wheels offset too much, it will easily cause chain disconnection and accelerated wear. When replacing the sprocket, you must pay attention to check and adjust the offset. After the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing. It is not possible to just replace a new sprocket or a new sprocket alone. Otherwise it will cause poor meshing and accelerate the wear of the new sprocket or new sprocket. When the tooth surface of the sprocket is worn to a certain degree, it should be turned over and used in time (referring to the sprocket used with adjustable surface) to extend the use time. The new sprocket is too long or stretched after use, making it difficult to adjust. You can remove the chain link depending on the situation, but it must be an even number. The chain link should pass through the back of the sprocket, the lock piece should be inserted outside, and the opening of the lock piece should face the opposite direction of rotation.

For bolts that have been rusted or have a lot of grease, solvents are often used to spray the joints of the bolts and nuts to allow the solvent to penetrate into the threads, which will be easy to disassemble. After the sprocket is severely worn, the new sprocket and the new sprocket should be replaced at the same time to ensure good meshing.
