Gear teeth calculations

The role of the liquid in lubrication is different and more complicated than this. Many lubrication problems deal with the behavior of the liquid as it is raised to a high pressure during rapid passage through a short conjunction. Some calculations have been made by Fein [47] for a film of oil between gear teeth operating under moderately severe conditions. The duration of the transit of the oil through the conjunction... 

In-spite of the assumptions employed to calculate the normal approach component, namely the parabolic approximation outside the Hertzian region and constant film thickness within it, it is believed that the analysis brings the mathematical representation o unsteady elastoh-ydrodynamic a step nearer to the situation encountered in such important applications as gear teeth, cams and rolling contact bearings. ...
