The Oil Condition Analysis of Involute Spur Gear
Applied Mechanics and Materials, 2012A gear microscopic surface pitting lubrication model was established, and the oil condition of it was introduced. Based on the multi-grid method, a numerical solution of spur gear oil condition lubrication was obtained. The result show that with the provided oil film thickness increases, the film thickness of the meshing point also increases.

The Efficiency of Involute Spur Gears
Journal of Mechanical Design, 1981Approximate equations produced by Trachman |15| are used to predict the coefficient of sliding friction between the gear teeth. These equations apply when the lubrication regime is elastohydrodynamic; this is true during many gear contacts. The equations, which require only certain basic characteristics of the lubricant and the gears, are relatively ...
