Timing Pulleys (also known as synchronous belt wheel), transmission is composed of a closed circular tape with equispaced teeth on the surface of the inner circle and the corresponding belt wheel. When moving, the tooth with the gear wheel meshes with the gear groove to transmit motion and power, which is a kind of meshing drive, so it has various advantages of chain drive and belt drive. Synchronous belt drive has accurate transmission ratio, no slip difference, can obtain a constant speed ratio, precision transmission, stable transmission, vibration absorption, small noise, large transmission speed ratio, generally up to 1:10, permitted line speed up to 50m/s, high transmission efficiency, generally up to 98%,-99%.Transfer power from a few watts to a few hundred kilowatts.
Its compact structure, suitable for multi-spindle drive, apply tension is small, without lubrication, no pollution, it can work in places where pollution is not allowed or the relatively bad working environment, also be allowed in contaminated places.
It is widely used in automobile, textile, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial equipment, stage lighting, communication, food machinery, medical machinery, steel machinery, petrochemical industry, instruments, precision machine tools and other fields.
