Circular pitch

P_c is the arc distance between two adjacent teeth. The pitch diameter is used for calculating the distance between the centers of gears.

Center distance:

c = {d_1 + d_2 \over 2} = {(N_1 + N_2)m \over 2}

Diametral pitch:

P = {N \over d}

Where:

• N is the number of teeth

Module:

m = {d \over N}
