(1) High precision The accuracy of the double-sided tooth timing belt directly affects the quality of the product, especially the mechanical and electrical integration products. Its technical performance, process level and function are greatly improved compared with ordinary mechanical products. The first requirement. If the accuracy of the mechanical system cannot meet the requirements, no matter how accurate the other systems of the mechatronics products work, they cannot complete their scheduled mechanical operations. (2) Quick response That is, the mechanical system is required to have a short time interval from receiving the command to starting the task specified by the command, so that the control system can timely issue commands according to the operating state information of the mechanical system to complete the task accurately. (3) Good stability That is, the working performance of the mechanical system is not affected by the external environment, and the anti-interference ability is strong. The double-sided tooth synchronous belt is a transmission part with the advantages of chain, gear and triangle tape.
