Inverse Involute

For many calculations – e.g. to determine the dimension over two balls from the tooth thickness – it is necessary to transform involute alpha to the pressure angle.

Diametrical Size at Reversal Point

There are different instruments to inspect the size over/between two balls. The most simple instrument is based on the rocking method. These hand-held instruments are equipped with measuring inserts and a dial indicator. The nominal size is adjusted by gauge blocks. Afterwards, the operator needs to find the reversal point to receive the relative deviation.
