同步带（Synchronous belt）.doc

同步带（Synchronous belt） The synchronous belt is made of steel wire or glass fiber as a strong layer, and is covered with polyurethane or neoprene ring belt, and the inner circumference of the belt is made into teeth, so that the belt is meshed with the toothed belt pulley. Synchronous belt transmission, transmission ratio accurate, the axial force is small, compact structure, good abrasion resistance, oil resistance, anti aging performance is good, the general use of temperature -20 and 80 DEG C, v50m/s, P300kw, i10, requirements for synchronous transmission can also be used for low speed transmission. The synchronous belt drive is composed of a circular belt with an equal spacing tooth profile on the inner surface and a wheel with corresponding anastomosis. It combines the advantages of belt drive, chain drive and gear drive. When rotating, the power is transmitted by engaging the teeth with the teeth of the wheel. Synchronous belt drive with accurate transmission ratio, no slip, can obtain a constant speed ratio, smooth transmission, vibration absorption, noise, transmission range is large, generally up to 1:10. Allow the line speed of up to 50M/S, transfer power from a few watts to 100 watts. High transmission efficiency, generally 98%, compact structure, suitable for multi axle drive, without lubrication, no pollution, so it can work in a place where pollution and work environment is not allowed to work properly. This product is widely used in textile, machine tool, tobacco, communication cable, light industry, chemical industry, metallurgy, instrument and meter, food, mining, petroleum, automobile and other industries, all kinds of mechanical transmission. [Edit] features of the sync belt (1) accurate transmission, no sliding at work, and constant transmission ratio; (2) stable transmission, with buffering and vibration damping capacity, low noise; (3) transmission efficiency is high, up to 0.98, energy-saving effect is obvious; (4) easy maintenance, no lubricati
