Conveyor Belt Development History

Apr 13, 2019

We all know that everything has its own development process from small to large, so what is the development process of the conveyor belt industry? What is his development trend? Let's take a look together.

First, from the material used in the transmission belt, the rubber has been developed from natural rubber to synthetic rubber, and further expanded to special synthetic rubber CSM, HNBR: the skeleton material is expanded from cotton fiber to rayon, polyester, nylon, fiberglass, Wire and aramid, etc., see Table 2. Product. In order to improve the durability of the V-belt, since the 1960s, a cut-type V-belt has appeared, and its side has no wrap, and the bending fatigue resistance is very good, and has replaced most of the wrap-around V-belts. On the other hand, after entering the 1980s, the V-belt tape with the flat belt and the V-belt was rapidly developed. Due to its excellent performance and sharp increase in output, the cutting V-belt has been partially replaced. Then, in the United States and Japan and other countries, a wedge-shaped V-belt appeared. Since the belt has a small thickness, a large contact area with the pulley, and good bending performance, it can be used on a small pulley, and thus contributes greatly to miniaturization and energy saving of the transmission. Furthermore, the principle of driving on the back of the belt can be used. For example, in the automobile fan, AC motor, power control system, air conditioner, etc., the so-called "snake drive" method that uses one drive belt for one drive has attracted attention from all walks of life. Increasingly. Representative products for such multi-faceted, multi-directional, multi-machine transmissions are hexagonal belts and round belts. The latest category of products in the drive belt is the toothed belt, also known as the timing belt. It combines the advantages of gears, chains and belt transmissions, and has the characteristics of high transmission efficiency, accurate transmission ratio, low noise, energy saving and convenient maintenance. Although its transmission principle appeared in 1900, several patents appeared. However, it was not until half a century later that industrialization began. In the 1980s, it finally became the leading transmission product of precision machinery. In particular, high-precision micro-belts made of saturated nitrile rubber and polyurethane elastomers have entered the high-tech field. The biggest difference between the toothed belt and the traditional transmission belt is: synchronization and mute. Therefore, it is the most respected environmentally friendly product today. In recent years, after the teeth of the toothed belt are changed from square teeth to scallops, the transmission force is further increased, and the development prospect is extremely broad.
