First of all, sprockets are widely used in the transmission systems of various vehicles and mechanical equipment. At present, they are basically based on domestic production. The sprockets produced by our merchants meet the needs of people and some products have been exported to various countries in the world. However, in the application of the automobile industry, the export of sprockets and gears is limited and can only basically meet the needs of our domestic automobile manufacturers.
Gearboxes in industry also often use our sprockets. In recent years, the introduction of foreign capital has gradually strengthened the development and demand of domestic industrial gearboxes. In recent years, considerable progress has been made in terms of product quality and technology. At present, some large domestic manufacturers have been able to compete with foreign manufacturers.
In terms of special wheel transmission, such as non-circular sprocket, plastic sprocket gear, powder metallurgy gear, small module gear, etc., China has not formed a leading enterprise at present, and the technological potential of the enterprise has yet to be developed. At present, our country has a supporting policy for connectors and fasteners, encouraging them to vigorously develop their own technology and strength and strive for breakthroughs in production and innovation.
