Graphical profiling of wheel teeth milled by rolling

Abstract

A device for large-scale graphic representation of wheel tooth profiles cut with rack and pinion tools using the running-in method has been developed. It uses a special template made of transparent sheet material (plexiglass), in which narrow slits are provided in scale in the shape of the cutting tool contour. On the lower plane of the template there are equally spaced parallel risks perpendicular to the risk coinciding with the middle dividing line of the rail.
