An Accurate Modeling Method of the Plane Enveloping Hourglass Worm

Applied Mechanics and Materials, 2011
This paper proposes a new method for creating the accurate 3D geometry model of the plane enveloping hourglass worm efficiently. The working tooth surfaces of the worm are enveloped by the mother plane surfaces. And according to the gear engagement theory, the equations of the surfaces enveloped are established. By combination with engineering practice,

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 ...
