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

Design and Investigation of an Asymmetric Logarithmic Spiral Gear Drive
Applied Bionics and Biomechanics, 2022 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 ...
