Abstract

Improvements in the manufacture of gears, of the type consisting of a gear and a worm, which rotate at a predetermined speed ratio around the axis that are not parallel or intersect, characterized in that the worm is provided with an outer surface that is a predetermined surface of revolution and a thread whose axial pitch, curvature and rate of change of curvature are equal to the pitch, curvature and rate of change of curvature of the "vectorial spiral of relative velocity" in other transverse planes of the worm, and the gear has teeth that mesh with the thread of the auger.
