Study on a Ball Screw (Part 3)

Measurment of the radius to the lace-way from the axis

Abstract

In this Part 3, the measuring method of the radius from the screw axis to any point on the lace-way surface of the nut or the threaded shaft of the ball screw is reported. There are many reports on the measuring method about the triangular hericoidal surface, but rather few about generalized hericoidal surface.
Here is reported a measuring method on latter and its theoretical calculation.
