Investigation of the effect of pressure angle on gear performance in asymmetric gears
Ali Keçici,Ali Ünüvar +1 more
TL;DR: In this paper, the effect of the change in pressure angle and profile crowning has been studied in two spur gear pairs with different tooth numbers, and it was observed that the asymmetric gear mechanism with the same gear main dimensions as the symmetric gears increased the load bearing capacity, performance, life, efficiency and reliability.

Direct Gear Design
TL;DR: In contrast, gear design methods have remained frozen in time, as the vast majority of gears are designed with standard tooth proportions as discussed by the authors, which is a sign of over-standardization.
Analysis and Testing of Gears with Asymmetric Involute Tooth Form and Optimized Fillet Form for Potential Application in Helicopter Main Drives
TL;DR: Gears with an asymmetric involute gear tooth form were analyzed in this article to determine their bending and contact stresses relative to the symmetric involutes gear tooth designs which are representative of helicopter main drive gears.
