WebFeb 17, 2024 · The pitch circle is a theoretical circle upon which all calculations are usually based [5]. The diametral pitch P is the ratio of the number of teeth on the gear to the pitch diameter. Thus, it is the reciprocal of the module in the metric system (ISO). Since diametral pitch is used only with U.S. units, it is expressed as teeth per inch. WebThe diametral pitch calculator quickly converts between module, diametral pitch, and circular pitch. A gear's pitch and number of teeth determine the overall size of the gear (and the blank you need to make that gear). A Gear Dimension C alculator can give you all of the physical dimensions on the gear (diameters and lengths of features on the teeth). …
