Hourglass Worm Gears Designed to Concentrate Surface Normals. Manufacturing and Experimental Investigation on Tooth Bearing.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994
To avoid the influence from the small displacement of gear axes under load, the authors propose that all contact normals of a tooth surface be at right angles to the direction of the small displacement induced at each contact point under load. On the basis of this state of surface normals, a few methods for tooth surface generation have been devised ...

A study on hourglass-worm gearings designed to concentrate surface normals. A gear disign using an hourglass-worm gearing with an arcuate tooth profile.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1990
In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that a projective group of the surface normals should be concentrated upon the intersection point of the plane perpendicular to the wheel axis and the axis about which the worm axis rotates, displacing its position relative to the wheel ...

A Study on Hourglass-Worm Gearing Designed to Concentrate Surface Normals. A Gear Design Using an Hourglass-Worm Gearing Whose Worm Tooth Surface Is Generated by the Grinding Wheel with an Involute Helicoid.

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1991
Displacement of the worm axis relative to the wheel axis under load is considered to be the helical movement rotating about the instantaneous axis. In order to avoid the influence of the displacement of gear axes under load upon tooth contact, the authors propose that the surface normals should be intersected perpendicular to the direction of helical ...
