Calculating the belt length and center distance
Using the tooth pitch T, the two numbers of teeth of the pulleys Z1/Z2 and the center distance A, the theoretical effective length of the belt can be calculated as follows:

In addition to the belt length, timing belts are often characterized by the number of teeth.
The number of teeth of the closed belt can be determined by the ratio between belt length and tooth pitch:
After selecting a standard belt length, the exact center distance can be calculated using the formula below:
