Tooth pitch (Tz) Tooth pitch is defined as the num-ber of teeth per inch (tpi). 1 inch corresponds to 25,4 mm. In the WIKUS range a difference is made between constant tooth pitches with regular tooth distance and variable tooth pitches with differing tooth distance within one toothing inter-val. Variable tooth pitches are marked

5. Tooth pitch (TPI) Tooth pitch is the number of teeth per inch (25,4 mm). A difference is made between constant tooth pitches with regular tooth distance and variable tooth pitches with differing tooth distance within one interval. Variable tooth pitches are marked by two measures, e.g. 2-3 TPI. With this, 2 TPI signifies the maximum tooth

For example: the circular pitch is p/DP; the standard tooth addendum is 1/DP; the standard tooth whole depth is 2.2/DP (or 2.25/DP); and the gear pitch diameter is n/DP (where n is a number of teeth). An important difference between the circular pitch and diametral pitch is that whole DP values are standardized (for example,
