Synchronous pulleys refer to those generally made of materials such as steel, aluminum alloy, cast iron, and brass, with inner holes in various forms including round holes, D-shaped holes, and conical holes. Synchronous pulley drive is composed of a closed annular belt with evenly spaced teeth on its inner surface and the corresponding pulleys. Synchronous belts can be classified by material into chloroprene rubber with fiber rope synchronous belts and polyurethane with steel wire synchronous belts. According to the shape of the teeth, they are mainly divided into two categories: trapezoidal teeth and arc teeth. According to the arrangement surface of the teeth, they can be further classified into single-sided tooth synchronous belts and double-sided tooth synchronous belts.
It is widely applied in fields such as automobiles, textiles, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial machinery, stage lighting, communication and food machinery, medical machinery, steel machinery, petrochemicals, instruments and meters, and various precision machine tools.
