For more than half a century, the technological development of the world's transmission belt has gone through the following stages:

First, from the perspective of materials used for transmission belt, rubber has developed from natural rubber to synthetic rubber, and further expanded to special synthetic rubber CSM and HNBR. The skeleton materials have expanded from cotton fiber to rayon, polyester, nylon, glass fiber, steel wire and aramid. See Table 2 for details. Products. In order to improve the durability of V-belt, cutting type V-belt has appeared since 1960s. It has no wrapping on the side and has good bending fatigue resistance, which has replaced most of the wrapping type V-belt.

On the other hand, after entering the 1980s, the V-shaped flat belt combined with flat belt and V-shaped belt has developed rapidly. Due to its excellent performance and rapid increase in production, it has partially replaced the cutting V-belt. Then, wedge-shaped V-belts appeared in the United States, Japan and other countries. Because of its thin thickness, large contact area with pulley and good bending performance, the belt can be used on small pulley, which makes great contribution to the miniaturization and energy saving of transmission device.

In addition, the principle that the back of the drive belt can also be driven is used. For example, in automobile fans, AC motors, power control systems, air conditioners, etc., the so-called serpentine drive mode with one drive belt has attracted the attention of all walks of life, and its application scope is expanding day by day. The representative products of this kind of multi face, multi direction and multi machine transmission are hexagonal belt and circular belt.


A new type of transmission belt is toothed belt, also known as synchronous belt. It integrates the advantages of gear, chain and belt transmission device, and has the characteristics of high transmission efficiency, accurate transmission ratio, low noise, energy saving and convenient maintenance. Although its transmission principle was as early as 1900, it didn't start industrialization until half a century later. Since 1980s, it has finally become the leading transmission product of precision machinery. In particular, the high-precision micro belt made of saturated NBR and polyurethane elastomer has entered the high-tech field. The difference between toothed belt and traditional transmission belt lies in synchronization and silence. Therefore, it is the most respected environmental protection products. In recent years, after the tooth of tooth belt is changed from square tooth to round tooth, the transmission force is further increased, and the development prospect is very broad.

Transmission belt is the power generated by the rotation of the motor or engine of the prime mover, which is transmitted to the mechanical equipment by the belt through the pulley, so it is also called power belt. It is the core connecting part of mechanical and electrical equipment, which has a wide variety of applications. From large to thousands of kilowatts of giant motors, to less than a kilowatt of micro motors, and even including home appliances, computers, robots and other precision machinery are inseparable from the drive belt. It is characterized by free speed change, far and near transmission, simple structure and convenient replacement. Therefore, from the original machinery to modern automatic equipment, there is the shadow of the transmission belt. The product has experienced many times of evolution, and the technology is becoming more and more mature.
