Generation of helical gears with new surfaces, topology by application of CNC machines [PDF]

open access: yes
Analysis of helical involute gears by tooth contact analysis shows that such gears are very sensitive to angular misalignment that leads to edge contact and the potential for high vibration.

Effect of operating conditions on gearbox noise [PDF]

open access: yes, 1992
Low contact ratio spur gears were tested in the NASA gear noise rig to study the noise radiated from the top of the gearbox. The measured sound power from the gearbox top was obtained from a near field acoustic intensity scan taken at 63 nodes just above

Comparison of Skin Model Representations and Tooth Contact Analysis Techniques for Gear Tolerance Analysis [PDF]

open access: yesJournal of Computing and Information Science in Engineering, 2015
To improve the tolerancing process in an industrial context, there exists a strong need for tolerance analysis to estimate the probability of scrap in an acceptable computer time and managing the accuracy of the results. The developed approaches for gear tolerance analysis based on simulation, depend on the type of the Skin Model representation, and on

Influence of linear profile modification and loading conditions on the dynamic tooth load and stress of high contact ratio gears [PDF]

open access: yes
A computer simulation for the dynamic response of high-contact-ratio spur gear transmissions is presented. High contact ratio gears have the potential to produce lower dynamic tooth loads and minimum root stress but they can be sensitive to tooth profile
