Synchronous toothed belt, also known as timing belt, is a flexible transmission form similar to common V-belt, flat belt and other belt transmission methods. Synchronous toothed belt is made of steel wire rope or glass fiber rope as the strong layer, covered with polyurethane or chloroprene rubber on the outside, and the inner circumference of the belt is made into a toothed shape to mesh with the toothed belt pulley. Due to the small deformation of the strong layer after bearing, the circumference of the toothed belt remains unchanged, so there is no relative sliding between the belt and the pulley, ensuring synchronous transmission and constant transmission ratio.

Compared with ordinary belt transmission, synchronous toothed belt has the advantages of minimal deformation of the strong layer made of steel wire rope under load, basically unchanged circumferential pitch of the toothed belt, no relative sliding between the belt and pulley, and balanced and accurate transmission ratio; ② The toothed belt is thin and lightweight, suitable for high-speed applications. The linear speed during transmission can reach 40m/s, the transmission ratio can reach 10, and the transmission efficiency can reach 98%; ③ Compact structure and good wear resistance; ④ Due to the low pre tension, the bearing capacity of the shaft is also relatively small; ⑤ Manufacturing and installation require high precision and strict center distance.

Maintenance precautions

1. Pre use inspection: Before using the synchronous belt, it is necessary to carry out inspection work and take corresponding measures for the existing problems. This can effectively avoid the occurrence of malfunctions caused by other issues during use, and the maintenance effect is very good.

2. Avoid overload use: Synchronous belts should strictly follow the prescribed requirements during use, and try to avoid overloading as much as possible, otherwise it is easy to cause breakage and affect the service life.

3. Cleaning work should be done well: The synchronous belt should be actively cleaned when in use or not in use, otherwise impurities or other stains may cause problems. This will also greatly shorten the service life.
