Measuring of a stub-gear

For measuring the tooth thickness (and backlash) one can use the double toothcaliper of Brown & Sharpe as for a gear with normal height. For that it is necessary to deduct from the measured value han (via the table) the difference between the module of the pitch and the module of the tooth depth (in mm).

The measuring across several teeth (method of Wildhaber) is applied as for normal teeth.
