Background In the fields of industrial automation, logistics transmission, precision machining and the like, synchronous belt transmission systems are widely applied to material conveying and power transmission. However, the conventional synchronous belt transmission system often causes problems of vibration, noise, equipment wear and the like due to uneven mass distribution or dynamic unbalance in the operation process, and seriously affects the stability and the service life of the equipment. In synchronous belt drive systems, the support, unpowered roller, etc. are typically mounted on one side of the synchronous belt on a working surface, while the other side of the synchronous belt lacks a corresponding balancing structure. The single-side load can cause vibration and swing of the synchronous belt during high-speed operation, and the transmission precision is affected. Because the dynamic unbalance problem of the traditional system is prominent, excessive wear is easy to occur in the running process of equipment, and the maintenance frequency and the cost are increased.

Further, the bracket and the first unpowered roller are arranged on one side working surface of the synchronous belt, and the counterweight component is arranged on the other side non-working surface of the synchronous belt, so that a bilateral symmetrical balance layout is formed. Further, the total mass of the counterweight assembly is equal to the total mass of the bracket and the first unpowered roller assembly. Further, the counterweight assembly is a block of high density metallic material.
