Research on Measuring Key Errors of Plane-Generated Enveloping Hourglass Worm

Abstract:

Plane-generated double enveloping hourglass worm pair has unique characteristics of double contact line; it has the advantages of wide tooth working area, large bearing capacity, and long service life, etc. However, its development has been restricted by such factors as difficulty in measuring, worse processing precision, etc. In this article, a modeling approach is presented in order to obtain the meshing point’s coordinates of the plane–generated enveloping hourglass worm based on theoretic analysis and computer-aided design principle. And a measuring equipment system is designed to measure the meshing point’s coordinates. Key errors of this worm have been discussed and obtained by comparing the theoretic coordinates and the measuring coordinates. Finally, an experimental study has been carried out to validate the modeling method and measuring equipment system.
