The article "Limitations of Worm and Worm Gear Surfaces in Order to Avoid Undercutting" appeared in the November/December 1990 issue of Gear Technology.

Summary
The dimensions of the worm and worm gear tooth surfaces and some of the worm gear drive parameters must be limited in order to avoid gear undercutting and the appearance of the envelope of lines of contact on the worm surface. The author proposes a method for the solution of this problem. The relations between the developed concept and Wildhaber's concept of the limit contact normal are investigated. The results of computations are illustrated with computer graphics.
