How to use the Pulley Distance Calculator
1. Enter the number of teeth on the largest pulley
2. Enter the number of teeth on the smallest pulley
Note: if 1:1 ratio, enter the same number of teeth in both boxes
3. Enter the belt tooth pitch in mm, i.e. T5 is 5mm, T2.5 is 2.5mm
4. Enter the belt length in mm
The resulting answer is shown in the bottom yellow box. For information, the PCD of the pulleys is also shown in the other yellow boxes.
In order to achieve the correct tension, one of the pulleys should be adjustable.
