What is a timing pulley?
The timing pulley is a special pulley with teeth or grooves around the outer diameter of the pulley body. The timing teeth mesh with the holes in the metal belt, while the timing slots mesh with the drive lugs on the inner circumference of the belt. These teeth or grooves are only used for timing, not for power transmission.
How does the timing pulley work?
The synchronous wheel drive consists of a ring belt with equidistant teeth on the inner circumference and a belt pulley with corresponding teeth. During operation, the teeth mesh with the grooves of the belt pulley to transmit motion and power and integrate with the belt. The utility model relates to a new belt transmission, which has the advantages of transmission, chain transmission and gear transmission.
