Checking the thickness of straight-tooth angular-wheel teeth by their edges

Conclusions

• 1. Above formulas are general and suitable for calculating dimensions required in the checking of corrected or uncorrected involute straight-toothed angular wheels with any number of teeth or any gear ratios. Since the deviations of the octoidal from the involute toothing is small, above formulas can be used for checking octoidal angular wheels with a sufficient degree of accuracy.

• 2. Above method, similarly to other known methods, requires careful axial adjustment in placing the balls and the conversion of measurement results to the size of teeth. It is suggested to make this conversion in terms of the most general parameter which characterizes the size of teeth, namely the divergence of the initial generating wheel. The conversion formulas are well-known and therefore omitted in this article.

• 3. In order to avoid in these measurements any mathematical calculations, which are very cumbersome for angular wheels, it is advisable to compile and issue tables which would eliminate the necessity for calculations.
