Design and meshing characteristics of curvilinear cylindrical gears with asymmetric teeth [PDF]

open access: yesScientific Reports
Current research on curvilinear cylindrical gears primarily focuses on symmetric teeth, with little attention given to curvilinear cylindrical gears with asymmetric teeth. To investigate the impact of asymmetric tooth design on the meshing performance of

A shape-independent analytical method for gear mesh stiffness with asymmetric spalling defects [PDF]

open access: yesScientific Reports
Spalling, a common failure mechanism of gear systems, greatly affects the dynamics of gears operation, which is reflected in the time-varying mesh stiffness (TVMS). Current TVMS models often overestimate the asymmetric spalling phenomenon and may lead to

Surface-energy ratchet motor with geometrical symmetry driven by biased random walk [PDF]

open access: yesScientific Reports
A geometrically symmetric gear with asymmetric surface wettability exhibits one-way spin on a vibrating water bed. On the side face of the gear, a parafilm was coated to create asymmetry in the surface energy.

Analysis of Transient Elastohydrodynamic Lubrication of Asymmetric Polymer Gear

open access: yesJixie chuandong, 2021
Polymer gears are light and corrosion resistant, which can reduce noise and improve economic benefits. Correspondingly, polymer gear teeth are weaker than metal ones, so asymmetric design is adopted to improve the strength of polymer gear.
