Timing pulley? What is it? What is it used for? I have never heard of it. I believe many people will have the same reaction after hearing this word. In simple terms, the synchronous pulley is composed of a driving wheel and a driving wheel. The driving wheel and a conveyor belt are composed of equidistant meshes on these three parts, and the conveyor belt is tightly sleeved on the driving wheel and the driven wheel. If you still can't imagine it, just think of it as the relationship between the chain and the wheel on the bicycle. However, the synchronous pulley is not used on the bicycle. It does not mean that the synchronous pulley is useless, but the characteristics of the bicycle make it The synchronous pulley cannot be used on bicycles, but it can be used on more advanced transportation tools, such as cars. The synchronous pulley's characteristics of reducing vibration and low operating noise are most suitable for use in cars, and are also used in chemical fiber, Textile machinery, cigarette machinery, papermaking, printing machinery, chemical industry, light industry, grain, food, machinery, mining, metallurgy, steel machinery, office equipment, medical equipment, communication equipment and various precision machine tools, precision instruments, etc. Don't look at it as just one part of so many machines. If a plastic crusher or the like lacks it, let alone crushing plastic, the machine will not even be able to do its job. In short, the synchronous pulley is a very important component and is It is widely used for transmission purposes and is much more advanced than chain drive.
