The main function of the trapezoidal rubber synchronous belt is to transmit power through the tooth-groove meshing of the belt teeth and the pulley to ensure the accuracy and efficiency of the transmission. This transmission method can ensure a strict transmission ratio and avoid the relative sliding problem in traditional friction-type transmission. It is particularly suitable for medium and low power transmission systems that require precise transmission ratios. Trapezoidal rubber synchronous belts have many advantages, including high transmission efficiency, precise transmission, low noise and low vibration. Its tight tooth-groove meshing design can effectively transmit power and improve transmission efficiency; at the same time, high precision and stability ensure the accuracy of transmission. In addition, due to its strong friction, strong tensile strength, good stability, anti-slip and wear resistance, the trapezoidal rubber synchronous belt has low noise and vibration during the transmission process, providing a comfortable working environment. Trapezoidal rubber synchronous belts are widely used in various mechanical equipment that require precise transmission, especially in industrial robots, textile machinery, medical equipment and other fields. In industrial robots, it can provide precise motion control, ensure that each joint moves according to the predetermined trajectory and speed, and improve work accuracy and repeatability. In addition, the trapezoidal rubber synchronous belt also has good wear resistance and fatigue resistance, and can withstand frequent starting, stopping and speed changing operations, extending service life and reducing maintenance costs.
