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

Investigation of the effect of pressure angle on gear performance in asymmetric gears
Meccanica, 2021 In this study, asymmetric gear mechanisms having the same working conditions, material and dimensions as symmetric gears but with different pressure angles were designed and compared with symmetric gear mechanism. The effect of the change in pressure angle and profile crowning has been studied in two spur gear pairs with different tooth numbers.

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

Analysis of Transient Elastohydrodynamic Lubrication of Asymmetric Polymer Gear
Jixie 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.
