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 ...

A Study on Hourglass Worm Gearing with Constant Slide-Roll Ratio

Journal of Mechanical Design, 1979
A new type of hourglass worm gearing is developed by the authors’ own theories [1], [2]. This hourlgass worm gearing has the good points of Hindley’s one and also covers the weak points of it. The worm is cut by a tool with straight-lined cutting edge which is fixed to the basic member [1].

Error-sensitivity analysis of hourglass worm gearing with spherical meshing elements

Mechanism and Machine Theory, 2013
Abstract This paper aims to study the influence of tooth errors and shaft misalignments on the tooth contact in hourglass worm gearing with spherical meshing elements. The geometries of the worm and worm-gear tooth surfaces are described, and the distribution characteristic of contact lines is explored.

Grinding of highly accurate hourglass worm gears — trial manufacture of the worm grinding device

Precision Engineering, 1990
Abstract Highly accurate worm gears can be effectively used as an angle standard. Wildhaber worm gearing is a kind of hourglass worm gearing, which owing to its geometrical simplicity, can have its worm and worm wheel easily finished and accurately measured. This study describes a precision grinding method of the Wildhaber worm. A hobbing machine can

Research on a Generating Method of Spiral Flutes of Hourglass Worm Gear Hob

Volume 10: 2017 ASME International Power Transmission and Gearing Conference, 2017
All of the cutting edges on an hourglass worm gear hob have different shapes and spiral angles. If the spiral angles are small, straight flutes are usually adopted. But for the hob with multiple threads, the absolute values of the negative rake angles at one side of the cutting teeth will greatly affect the cutting performance of the hob if straight ...
