The Significance and Purpose of Study on the Zero-Backlash High Precision Roller Enveloping Reducer

2021
Traditional worm drive shaft is mainly used for two interleaving, large transmission ratio, self-locking or the case of intermittent operation. Due to the advantages of smooth transmission, low noise, low impact load, and self-locking, it has been widely used in national defense industry, metallurgy, shipbuilding, construction and other industries as ...

Performance Testing Method for Roller-Enveloping Toroidal Worm Gear Reducers Considering Roller Preload

Roller preload is a critical factor influencing the transmission performance of zero-backlash high-precision roller enveloping reducers (ZHPRER). Due to the unique transmission structure of the ZHPRER and the self-spinning behavior of the worm wheel rollers, it is challenging to precisely regulate and measure the roller preload, as well as to clearly ...

Time-varying mesh stiffness analysis of a single-roller enveloping hourglass worm gear

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2018
As a new type of transmission, the single-roller enveloping hourglass worm gear (SEHWG) is widely used in precision mechanical transmission systems. Time-varying mesh stiffness (TVMS) is one of the most important excitations, which has great influences on the dynamic characteristics of SEHWG systems.

Meshing Characteristics and Engagement of Anti-Backlash Single- and Double-Roller Enveloping Hourglass Worm Gear

Volume 14: Design, Systems, and Complexity, 2019
Abstract Anti-backlash roller enveloping hourglass worm gears, as a new precision transmission system, has been extensively applied in robot joint design, packaging production line, and CNC (computer numerical control) machine tools. However, their corresponding transmission principles are seldom reported in the literature.
