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 ...

6th International Power Transmission and Gearing Conference: Advancing Power Transmission Into the 21st Century, 1992
Abstract For moderating the edge contact of gear tooth surfaces on load, a new concept has been proposed on designing worm gearing. As a first step of research, restricting a field of application of the designing concept, a few methods for generating tooth surface of hourglass worm gearing having a small lead angle have been devised.

A Novel Error Detection and Compensation Method of Hourglass Worm Gear Hob
Volume 3: Design, Materials and Manufacturing, Parts A, B, and C, 2012The double enveloping hourglass worm gear pair is a type of transmission, which has many traits, such as more teeth in mesh for transmission, higher contact quality, better lubrication condition and so on. Therefore, it has higher efficiency of transmission, stronger bearing capacity and longer work life.

Journal of Mechanical Design, 2019
This paper proposes a single-roller enveloping hourglass worm gear design and verifies its advantages compared to the existing double-roller worm gear system and the conventional worm gear set. Our hypothesis is that the single-roller worm gear with appropriate configurations and parametric values can eliminate the backlash in mating gear transmission ...
