Lubricant Jet Flow Phenomena in Spur and Helical Gears
The article "Lubricant Jet Flow Phenomena in Spur and Helical Gears" appeared in the January/February 1987 issue of Gear Technology.
In the gearing industry, gears are lubricated and cooled by various methods. At low to moderate speeds and loads, gears may be partly submerged in the lubricant which provides lubrication and cooling by splash lubrication. With splash lubrication, power loss increases considerably with speed. This is partially because of churning losses. It is shown that gear scoring and surface pitting can occur when the gear teeth are not adequately lubricated and cooled.
