A Study on Hourglass Worm Gearing With Developable Tooth Surfaces

Journal of Mechanical Design, 1978
The authors developed a new type of hourglass worm gearing based on the authors’ own theories [1, 2]. The worm having the developable tooth surface can be ground precisely. The pair of the tooth surfaces of the gearing have comparatively small relative curvature and contact with each other with the contact line lying perpendicularly to the relative ...

Principle and Practice of the Measurement for Hourglass Worms and Hobs

Applied Mechanics and Materials, 2017
Compared with cylindrical worm gears, hourglass worm gears have better transmission performance. The measurement of the hourglass worms and the hobs is a critical issue to restrict the application of the hourglass worm gear transmission. To solve this problem, an hourglass worm and hob measuring principle and a measuring machine which achieves the ...

A General Modification Theory for Double-Enveloping Hourglass Worm Drives

Key Engineering Materials, 2011
A universal modification theory is developed for all kinds of hourglass worm drives, no matter what shape the generating surface of the worm is. Based on the theory established, toroidal worm drives can be classified into two main categories: with singular points and without singular points.
