This document describes the thread profiles of the five most common worm profile types and provides formulae of their axial profiles.
The five worm profile types covered in this document are designated by the letters A, C, I, K and N.
This document provides the formulae to calculate the path of contact, the conjugate profile of the worm wheel, the lines of contact, the radius of curvature and the velocities at points of contact. The application of those formulae to calculate parameters used in load capacity calculations are provided in 11.11.
