The pitch circle is theoretical circle upon which all calculations are usually based; its diameter is the pitch diameter The pitch circles of a pair of mating gears are tangent to each other. A pinion is the smaller of two mating gears. The larger is often called the gear. The circular pitch p circular pitch p is the distance, measured on the pitch circle, from a point on one tooth to a corresponding point on an adjacent tooth. Thus the circular pitch is equal to the sum of the tooth thickness and the width of space. The module m module m is the ratio of the pitch diameter to the number of teeth. Nomenclature
