In the course of driving chain development, besides the development of chain products and the appearance of new materials, the Driving chain manufacturer has enhanced the function of driving chain and improved the overall strength and rigidity. Besides, the appearance of the programmable controller and computer is a huge driving force for the development of the driving chain. The electric control system of driving chain is equipped with high precision, high sensitivity and high-reliability speed control, signal acquisition, signal transmission and logic execution components, which make the electric control level of driving chain change by leaps and bounds and make it possible to realize some complicated automatic transmission lines with logic network function.

The structure of driving chain products is complex. Usually, they are assembled from rollers, sleeves, pin shafts, chainplates and other parts. However, for those non-standard chains, there are more than seven or eight kinds of parts but as many as dozens of kinds of parts. These parts are limited by processing skill and equipment. Some need to be purchased from external processing, while others need to be processed by themselves. In addition, the production process often changes, so the calculation and arrangement of production and operation are very complicated.
