The Lubrication of Gears - Part II - May/June 1991
The article "The Lubrication of Gears - Part II" appeared in the May/June 1991 issue of Gear Technology.
What follows is Part 2 of a three-part article covering the principles of gear lubrication. Part 2 gives an equation for calculating the lubricant film thickness, which determines whether the gears operate in the boundary, elastohydrodynamic, or full-film lubrication regime. An equation for Blok's flash temperature, which is used for predicting the risk of scuffing, is also given.
