What is diametral pitch of a gear?

The number of teeth of a gear per inch of its pitch diameter. A toothed gear must have an integral number of teeth. The circular pitch, therefore, equals the pitch circumference divided by the number of teeth. The diametral pitch is, by definition, the number of teeth divided by the pitch diameter.

How to Calculate Diametral Pitch?

Diametral Pitch calculator uses Diametral pitch=Number of teeth on the wheel/Diameter of the pitch circle to calculate the Diametral pitch, Diametral Pitch is number of teeth of a gear per inch of its pitch diameter. . Diametral pitch and is denoted by Pd symbol.
