The difference and selection of trapezoidal tooth synchronous belt and arc tooth synchronous belt
1) The polygon effect of the arc tooth timing belt is much smaller, because the meshing of the belt teeth and the gear teeth is better, so the transmission accuracy is also higher;
2) From the belt type selection chart in the manual, the low-speed bearing capacity of the arc teeth is larger;
3) In general, arc teeth are more expensive.
Conclusion: Trapezoid teeth have polygon effect, and arc teeth have better comprehensive performance.
