[0015] Specifically, the internal toothed belt may be meshed with a gear or the like, thereby driving the synchronous belt to rotate.

[0016] As a further description of the above technical solution:

[0017] The number of the tensile-resistant glass fiber cords is no less than six, and the tensile-resistant glass fiber cords are evenly distributed inside the middle layer along the horizontal plane direction.

[0024] Specifically, the outer arc layer and the middle layer are bonded together by a bonding layer 1 which is thinner than the outer arc layer, and then the middle layer and the inner layer are bonded together by a bonding layer 2, and the outer arc layer 1, bonding layer 1 2 and middle layer 3 which together constitute the belt body of the synchronous belt have a thickness ratio of 1:0.3:1. While ensuring the bonding effect, the thickness of the belt body of the synchronous belt can be reduced as much as possible, so that it is more convenient to use in daily use.

[0025] As a further description of the above technical solution:

[0026] The outer wall of the outer arc layer is provided with a wear-resistant coating.

[0027] Specifically, the wear-resistant coating is made of epoxy resin. Coating the outer wall of the synchronous belt with the wear-resistant coating can protect the synchronous belt and make it have better wear resistance.
