Synchronous pulley consists of a circular belt with evenly spaced teeth on its inner circumference and a correspondingly engaging pulley. It combines the advantages of belt drives, chain drives, and gear drives. During transmission, power is transferred through the meshing of the belt teeth with the pulley's tooth grooves.
Synchronous pulley offers precise transmission ratios, no slippage, and constant speed ratios, ensuring smooth operation, vibration absorption, low noise, a wide range of transmission ratios (up to 1:10), and allowable linear speeds of up to 50 m/s. It can transmit power from a few watts to hundreds of kilowatts. With high transmission efficiency, generally reaching 98%, it is compact, suitable for multi-shaft transmission, and requires no lubrication, making it pollution-free and ideal for environments where contamination is not allowed or where working conditions are harsh.
