Numerical and experimental research of helical gear contact stress considering the influence of friction

open access: yesFrontiers in Mechanical Engineering, 2022
Helical gears are widely used in various mechanical transmissions. Thus, analysing gear contact stresses is crucial to improve the fatigue limit and life of gears. In this paper, the contact stress of helical gear is analyzed by finite element simulation

Effect of Contact Geometry on the Contact Stresses in a Flat with Round Edge Contact

open access: yesFrattura ed Integrità Strutturale, 2019
The blade-disc dovetail interface in an aero-engine compressor is characterized by a non-uniform pressure distribution which can be obtained by an equivalent flat with round edge-on-plate configuration. The contact tractions for a mating pair are affected by many parameters which include, contact geometry, loading conditions, and material properties ...

Contact mechanics for randomly rough surfaces [PDF]

open access: yes, 2006
When two solids are squeezed together they will in general not make atomic contact everywhere within the nominal (or apparent) contact area. This fact has huge practical implications and must be considered in many technological applications.

Influence of tooth flank modification on tooth surface damage of conical involute gears

open access: yesNihon Kikai Gakkai ronbunshu, 2015
The conical involute gears have been applied to automotive parts such as 4WD transfer. The conical gear pair has characteristic large ease-off and this is equivalent to meshing of cylindrical gears which has large crowning for lead direction ...

Contact effects in bending affecting stress and formability [PDF]

open access: yes, 2010
If a strip is pulled over a curved tool there is a contact stress acting on the strip. This contact stress changes the stress state in the material, which is analysed with a simple model.
