The development trend of the world's drive belt in the half a century, with the rapid development of the global high-tech industry, the main trend of the future is to develop in the direction of miniaturization, precision and high speed. The old style tablet will be phased out, the new type of circular plate with a new rise; cutting triangle belt will replace most of the V belt, with the era of the V type flat belt, multi wedge belt, toothed belt may become the new mainstream products.

In addition to the introduction of a small number of technical equipment and joint ventures, mostly in the backward state, to restructure, reform, reform. Adjust the drive belt industry structure, elimination of old products, product development and innovation, catch up with the world's transmission with advanced technical level, can be said to be the most urgent task
