Products: belt drive pulley is to rely on friction or engagement between the outer edge, chain drive sprocket gears are meshing by chain link and pass through the rotational force to the driven shaft of the drive shaft in the middle of the flexible member. Belt drive and chain drive commonly used to transmit torque and speed change under conditions of greater distance. Both transmission structures are relatively simple, low cost, widely used in industry, is a common form of mechanical transmission. Many belt drive classification methods are usually classified from the following two aspects. 1, according to the classification of a drive principle) friction belt drive. It consists of a drive pulley, a driven pulley and an endless belt or several root composition. On the endless belt tensioning pulley. Due to the pressure generated between the tension belt and pulley, when the relative rotation between the two which produce friction. So, take the initiative to turn the cycle when using this friction drive belt movement, and took advantage of the friction drive belt driven reincarnation. This put the motion and power transmission drive shaft to the driven shaft. Therefore, the belt drive is a belt for the middle of the flexible member and by friction drive system to deliver power and movement. 2) mesh type belt drive. Mating-type belt drive is to rely on alveolar scoliosis band on the outer edge of the pulley teeth meshed achieve transmission, typically engaging style belt drive, which is the belt drive, belt drive and gear is a combination of a new Transmission. Belt with polyurethane or neoprene rubber matrix, thin rope or glass fiber tensile body, high tensile strength, after deformation under load. The drive is compact structure, transmission power of up to several hundred kilowatts, high transmission efficiency, with a speed of up to 40-80m / s, the transmission ratio is large and accurate. Its main drawback is the manufacture and installation of high precision, center distance demanding. Currently, the belt drive has been widely used in CNC machine tools, textile machinery and computers and other devices. 2, according to a cross-sectional shape of the belt classification 1) flat belt. Cross-sectional shape of a rectangular flat belt, which working surface is an inner surface in contact with the pulley. Common flat with tape, nylon braid and power and so on. 2) V belt (belt). Cross-sectional shape of an isosceles trapezoid V belt, a groove on the pulley. Both sides of the V-belt for the face, can be applied to a group, the larger its transmission power. 3) circular band. Circular in cross section, is used only for low power transmission. 4) V-ribbed belt. It is based on a flat belt drive belt on the V-belt composed of a plurality. Compact ribbed belt structure, can deliver a lot of power. 5) belt. Serrated longitudinal section, mainly for high-power, the transmission ratio demanding situations.
