Point-Contact Hourglass Worm Gears. (Crowning Method, the Analysis of Tooth Contact and Kinematic Precision of the Gearing).

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1995
In this paper, a method of crowning is proposed for hourglass worm gears to obtain the manner of point-contact with the aim of controling the sensitivity to various errors. In the studied worm gears, the worm is generated from a basic member with a plane or a spherical surface.

Accuracy Control of Hourglass Worm Gearing. Analysis of Tooth Shape and Tooth Contact.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1998
Feeding under-cutting of Lorentz wheel cutting method of Hindley hourglass worm gearing is analyzed at first. And the shape of the wheel tooth surface is made clear by the analysis and the measuring method of the wheel by 3-dimensional coordinate measuring machine is proposed. Statical and dynamical tooth contact are analyzed to control the accuracy of
