Curvilinear toothed timing belts are similar to traditional synchronous belts, but with teeth that have a curved shape instead of the standard trapezoidal shape. This design allows for a larger contact area between the belt and the pulley, which can result in higher torque transmission and smoother operation. The shape of the teeth is optimized to provide maximum power and efficiency, making curvilinear toothed timing belts ideal for high-performance applications and precision machinery. They are commonly used in industries such as automotive, aerospace, and robotics. Compared to ordinary trapezoidal toothed synchronous belts, the more scientifically robust structure of the Curvilinear Toothed Timing Belt has resulted in a reasonable improvement in performance.
