Drive transmission industry in China has also undergone years of development and change, and every technology in the steady ascend, from agriculture, high-tech automation machinery and equipment of high demand, stimulate the mechanical demand on the transmission of synchronous belt wheel; From the industrial point of view, drive transportation industry is the basis of production manufacturers, industrial manufacturers need to make a profit in the hands of manufacturing sales, production capacity is life for enterprise, low capacity will be eliminated by the market, and the efficiency directly depends on the transmission industry development. Production line of goods distribution, goods inspection, packaging industry used in belt transmission signal control equipment. Today's industry are interrelated, mutual restriction. So it is particularly important to drive the progress and development of the industry itself. Design used in the past, the drive industry belt as indoor and outdoor distribution equipment, due to the backward technology and low belt price. Can say is all the rage at the time. A few years after the country puts forward the comprehensive automation requirements, have made a big breakthrough in mechanical control, and new materials has a great development, makes the enterprise have to technology innovation by the belt transmission. Rubber material as the transmission medium, it seems, is a bit heavy, appearance and performance to its almost invisible in the automatic generation of modern equipment. The end of last century the integrated circuit has been developed vigorously, computer control and intelligent control circuit have become the main means. Today, industries in a certain speed development, the electronic and material update quickly, to keep up with the pace of synchronous transmission, shorten development cycle time, faster time-to-market, let other industries immediately update experience in new technology. Therefore, transmission industry still has obvious potential improvement space.
