[0017] refer to Figure 1 , Figure 2 , Figure 3 A synchronous belt includes a belt body 1. The inner wall of the belt body 1 has a plurality of belt teeth 101 distributed sequentially along its length. Adjacent belt teeth 101 engage with the inner wall of the belt body 1 to form a transmission groove 102. A tooth cover 2 is detachably connected to each belt tooth 101, and the tooth cover 2 is shaped to fit the belt tooth 101. The tooth cover 2 is made of polyurethane or nylon material.

[0018] The function of the tooth cover 2 is to prevent the transmission efficiency of the belt teeth 101 from being affected by wear or deformation. At the same time, protective plates 201 are provided on both sides of the cover. Adjacent protective plates 201 abut against each other to cover the inner wall of the transmission groove 102. The setting of protective plates 201 further increases the protection of the transmission groove 102. The synchronous belt meshes with the tooth groove of the synchronous pulley to transmit power. The setting of the belt teeth 101 cover and protective plates 201 can avoid direct contact between the belt teeth 101 and the transmission groove 102 and the tooth groove of the synchronous pulley, reduce the wear of the belt teeth 101, thereby maintaining the shape and wear resistance of the belt teeth 101 and effectively extending the service life of the belt teeth 101.
