Polyurethane synchronous belt is the prime mover motor or produced by the rotation of the engine power, through the synchronous belt wheel of polyurethane synchronous belt transmission to the machinery and equipment, so it is also called dynamic belt (synchronous belt). It is the core connecting part of the electromechanical equipment, the variety is very wide and the use is very broad. From big to thousands of kilowatts of giant motor, small to less than a kilowatt of micro motor, even including precision machinery, such as household appliances, computer, robot, cannot leave the synchronous belt. Its main feature is that it can be free and variable, which is very simple and easy to change. So, from the original machine to the modern automatic equipment all has synchronous belt, the product has evolved many times, the technology is ripening.

To develop linear positioning, transfer of control and transmission market polyurethane products the United States Gates Mectrol company also launched a polyurethane synchronous belt and conveyor belt for the food industry. The new product is a 3mm band, which is small and soft, making it easy to transfer from one conveyor to another. Polyurethane synchronous belt and conveyor belt conveyor belt flexibility is better than the plastic link type, and the food industry must often clean, so plastic chain belt needs a large number of cleaning, and the polyurethane conveyor belt is easy to clean. The other plastic chain is susceptible to residual bacteria, which also takes time to remove. GatesMectrol's new polyurethane sync band does not leave a lot of bacteria behind and clean up quickly.

The latest category in the belt is the toothed belt, also known as the synchronous belt. It combines the advantages of gear, chain and drive device with high transmission efficiency, accurate transmission ratio, low noise, energy saving and easy maintenance. Its transmission principle, though there are a few patents appear as early as 1900, but it was not until half a century later industrialization began, in the 80 s turned out to be the dominant of precision mechanical transmission products. In particular, high-precision microbelts made from saturated chloroprene and polyurethane elastomer are in high and new technology.

In recent years, with the rise of new and high technology industries, the use of new materials produced by belt has gradually replaced traditional products, especially the polyurethane synchronous belt and belt.

In recent years, with the rise of new and high technology industries, using new materials produced by synchronous belt has been gradually replacing traditional products, especially the polyurethane synchronous belt. At present, the German Jin Ke Lin, Swiss khabarov base, radar, and the Japanese companies such as SAN tin, is the well-known large companies of this field, and to give priority to with polyurethane high-grade and special micro zone as its leading products to develop.
