The double-sided toothed timing belt is recognized, recognized and widely used in the industries of machinery, textiles, precision instruments, petrochemicals, communication cables and other industries due to its lightweight structure, slip-free meshing transmission and low noise. It not only combines the advantages of gear transmission, chain transmission and belt transmission, but also overcomes the shortcomings of other transmission belts such as slippage and elongation, and forms a unique transmission mode. It also has a constant speed ratio, a large speed range, a compact structure, and a farm. Multi-axis transmission, oil resistance, moisture resistance, no need for lubrication and many other advantages are deeply rooted. The successful development of double-sided toothed belts requires the use of a single belt drive and the direction is opposite, or the installation position is particularly compact, or the main transmission and auxiliary transmission linkage and other fields with high transmission requirements all reflect its excellence; The superb winding performance, super high tensile strength, precise meshing, low signal-to-noise ratio and so on, all leave a good impression on users. Its obvious price advantage has made a solid step for domestic synchronous belts to replace similar foreign products. Moreover, in China, many companies have introduced a large number of foreign advanced equipment, and these advanced machinery and equipment have adopted a large number of synchronous belts. This precisely provides a huge business opportunity for the timing belt. Especially on some special equipment, the double-sided toothed timing belt is more effective. Often after these transmission belts are damaged, users cannot find synchronous products, and the road is far away, and they seek longevity help from our company. Examples like this are endless. Some manufacturers, while introducing foreign equipment, imitated various types of foreign machinery and equipment in order to reduce manufacturing costs and equipment costs. Therefore, many supporting timing belts and supporting products were born, and on this basis, digested the advanced ideas of foreign manufacturing machinery and equipment and developed and improved, creating superior conditions for the rapid development of precision transmission in the machinery industry.
