Study on the roller enveloping end face internal engagement worm gear

Journal of the Brazilian Society of Mechanical Sciences and Engineering, 2017
A novel worm gear, named roller enveloping end face internal engagement worm gear, with multiple worm-wheel meshing is proposed to provide multiple outputs with high transmission efficiency and good lubrication for furthering industrial advances. As such, an original worm transmission device with roller enveloping internal end-face meshing was proposed

Parametric Study of Meshing Characteristics With Respect to Different Meshing Rollers of the Antibacklash Double-Roller Enveloping Worm Gear

Journal of Mechanical Design, Transactions of the ASME, 2012
Roller shapes play a very critical role in the performance of antibacklash double-roller enveloping hourglass worm (ADEHW) gears; however, their influence is seldom reported in the literature. Based on the theories of differential geometry and gear meshing, this paper presents generic models of meshing characteristics for ADEHW gears, including both ...

Investigation on the Backlash of Roller Enveloping Hourglass Worm Gear: Theoretical Analysis and Experiment

Journal of Mechanical Design, Transactions of the ASME, 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 ...

An optimal process of machining complex surfaces of anti-backlash roller enveloping hourglass worms

Journal of Manufacturing Processes, 2020
Abstract Anti-backlash roller enveloping hourglass worm gear drives, as a new precision transmission system, has been extensively applied in robot joint design, and CNC (computer numerical control) machine tools. However, tooth profiles of the roller enveloping hourglass worms are spatial complex surfaces and very difficult to machine.
