The main drive mainly adopts high-torque arched synchronous belt transmission, yet noise plays a crucial role in evaluating machine tool performance. How can synchronous wheels reduce machine tool noise?

1. Addressing the source, due to the shape and position tolerances of the synchronous wheel itself, when the two synchronous belt wheels rotate, they produce noise due to unbalanced centrifugal force. Therefore, when selecting synchronous belt wheels, it is essential to choose high-quality and high-precision synchronous belt wheels.

2. Addressing the noise propagation pathways, synchronous belts and their pulleys generate aerodynamic noise due to the disturbance of gases during their engagement.
