Background

The synchronous belt and the synchronous belt wheel are a meshing pair in synchronous belt transmission. In order to make the tooth form 10 of the synchronous belt 1 smoothly mesh with the synchronous pulley and make the noise less, a process rib groove 12 (see fig. 2) is provided in the middle of the existing synchronous belt tooth groove 11. Due to the limitation of the synchronous belt structure, the depth of the process rib groove is mostly at the position of the steel wire rope of the synchronous belt, so that the steel wire rope 13 is directly exposed in the gap of the process rib groove 12. Although the silent cloth 14 is contained on the tooth-shaped surface, the steel wire rope 13 is just shielded, and the steel wire rope is not prevented from being communicated with the atmosphere, and in addition, due to the air permeability of the silent cloth, the steel wire rope can still contact the moisture in the air and other working conditions in the running process of the synchronous belt, so that the steel wire rope is rusted and corroded, even is broken, and the early failure of the synchronous belt is caused.

Therefore, if necessary process measures and manufacturing methods are not adopted, the service life of the synchronous belt is greatly shortened due to corrosion and rusting of the steel wire rope of the synchronous belt, the production efficiency and the reliability of equipment are reduced, and the requirements of modern industrial development are not met.
