The timing belt is made of steel wire rope or glass fiber as a strong layer, and an endless belt covered with polyurethane or neoprene. The inner circumference of the belt is made into a tooth shape to make it mesh with the toothed pulley.
When the synchronous belt is driven, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, the oil resistance, the wear resistance is good, the aging resistance is good, the general use temperature is -20 ℃-80 ℃, v <50m / s, P <300kw, i <10, can also be used for low-speed transmission for the transmission that requires synchronization.
Synchronous belt drive is composed of an endless belt with inner teeth on the inner peripheral surface and wheels with corresponding matching. It combines the advantages of belt drive, chain drive and gear drive. When rotating, the power is transmitted through the meshing of the toothed groove of the wheel. Synchronous belt transmission has an accurate transmission ratio, no slip, can obtain a constant speed ratio, smooth transmission, can absorb vibration, low noise, large transmission ratio range, generally up to 1:10. The allowable linear speed is up to 50M / S, and the transmission power is from several watts to hundreds of kilowatts. The transmission efficiency is high, generally up to 98%, the structure is compact, suitable for multi-axis transmission, no lubrication and no pollution, so it can work normally in places where pollution is not allowed and the working environment is harsh. Synchronous belts are widely used in various types of mechanical transmission in textile, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instrumentation, food, mining, petroleum, automobile and other industries.
