Synchronous belt is a ring belt with steel wire rope or glass fiber as the force layer, and polyurethane or chloroprene rubber as the outer cover. The inner side of the belt is made into gear shape for meshing with the gear synchronous belt pulley.
When transmitting by synchronous belt, the transmission ratio is accurate, the force on the shaft is small, the structure is compact, oil-resistant, wear-resistant, and has good anti-aging performance. The general operating temperature is -20℃ to 80℃, v<50m/s, P<300kw, i<10. It can also be used for low-speed transmission when synchronization is required.
Synchronous belt drive consists of a looped belt with equidistant gear shapes on its inner circumference and wheels that match it. It combines the advantages of belt drive, chain drive, and gear drive. When rotating, power is transmitted through the meshing of the belt teeth with the wheel grooves.
Synchronous belt drive has an accurate transmission ratio, no slippage, 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 velocity can reach 50M/S, and the transmitted power ranges from several watts to hundreds of kilowatts. The transmission efficiency is high, generally reaching 98%, the structure is compact, suitable for multi-shaft transmission, no lubrication required, no pollution, so it can work normally in places where pollution is not allowed and the working environment is relatively harsh.
This product is widely used in various types of machinery transmissions in industries such as textiles, machine tools, tobacco, communication cables, light industry, chemical industry, metallurgy, instruments, food, mining, petroleum, and automobiles.
