A Novel Error Detection and Compensation Method of Hourglass Worm Gear Hob

Volume 3: Design, Materials and Manufacturing, Parts A, B, and C, 2012
The 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.

Determination of the Most Dangerous Meshing Point for Modified-Hourglass Worm Drives

Journal of Mechanical Design, 2013
A type of modified-hourglass worm gear drive, frequently called type-II worm gearing for short, has various favorable meshing features. Its sole shortcoming is the undercutting of the worm wheel. By adopting a slight modification, this problem can be overcome due to the removal of a part of one subconjugate area containing the curvature interference ...

Determination of the Most Dangerous Meshing Point for Modified Hourglass Worm Drives

Volume 8: 11th International Power Transmission and Gearing Conference; 13th International Conference on Advanced Vehicle and Tire Technologies, 2011
A kind of modified hourglass worm drives, which is frequently called the type II worm gearing for short, has various favorable meshing features. Nevertheless, its sole shortcoming is the undercutting of the worm wheel. In the condition of adopting slight modification, this problem can be overcome due to the removal of a part of one sub-conjugate area ...
