The module is the measure of gear tooth size which is normally used for metric system gears. It is similar to the Diametral Pitch (DP), which is commonly used for UK system (inch measure) gears but they differ in the units used and in that they bear a reciprocal relationship. Module is the pitch circle diameter divided by the number of teeth. Module may also be applied to UK system gears, using inch units, but this usage is not in common use. Module is commonly expressed in units o… WebThe diameter symbol is only required if you are trying to control a cylindrical feature. In your specific case, the location of the center plane as defined by the edges of the square hole, is what is being controlled. ...
