Precision measurement of planar double-enveloping hourglass worms
Measurement: Journal of the International Measurement Confederation, 2016Abstract The measurement of planar double-enveloping hourglass worms has always been a technical problem in the field of gear metrology. To solve this problem, we propose a new method and develop a measuring machine to inspect each deviation of the worms.

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 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].

Grinding of highly accurate hourglass worm gears — trial manufacture of the worm grinding device
Precision Engineering, 1990Abstract 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

A Method to Generate the Spiral Flutes of an Hourglass Worm Gear Hob
Journal of Mechanical Design, 2018All 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 typically adopted. However, for hobs with multiple threads, the absolute values of the negative rake angles on one side of the cutting teeth will greatly affect the cutting performance of the hob if ...
