Synchronous pulley drive includes an annular belt with central teeth on the inner peripheral surface and a belt pulley with corresponding teeth. It is a new type of belt transmission that combines the advantages of belt transmission, chain transmission, and gear transmission. During operation, the belt teeth mesh with the grooves of the belt pulley to transmit movement and power.
Synchronous pulleys are usually made of steel, aluminum alloy, cast iron, brass, and other materials. The inner cavity has circular, D-shaped, and tapered holes. Surface treatment includes natural color oxidation, blackening, galvanizing, high-frequency quenching, etc. The level of accuracy depends on the customer's requirements.
Application of synchronous pulley:
Synchronous pulleys are widely used in automobile, textile, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial machinery, stage lighting, communication food machinery, medical machinery, steel machinery, petrochemical, instrumentation, various precision machine tools, and other fields.
