Design and Investigation of an Asymmetric Logarithmic Spiral Gear Drive
Sliding on gear teeth working surfaces has negative effects on the performances of gears, such as tooth surface wear, pitting, etc. In order to reduce the gear sliding during high speed and heavy load, a new type of pure rolling gear, named as an ...

Analysis of Transient Elastohydrodynamic Lubrication of Asymmetric Polymer Gear
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.

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

Reduction of Noise and Vibration of Spur Gear by Using Asymmetric Teeth Profiles with Tip Relief
Reduction of noise and vibration in spur gear experimentally by using asymmetric teeth profiles with tip relief was presented. Both of classical (symmetric) and asymmetric (with and without tip relief) spur gears are used in this work.

Exact Solution of Mesh Stiffness and Analysis of Tooth Profile Parameters for Asymmetric Gear Pairs
Asymmetric gears are a new type of involute gears with different pressure angles on each side of a gear tooth. Gear tooth profile parameters have a great influence on the performance of a gear pair, such as its tooth profile shape, motion characteristics,

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