Lubricant Jet Flow Phenomena in Spur and Helical Gears with Modified Addendums--for Radially Directed Individual Jets

Abstract

This paper develops the mathematical relations for the Virtual Kinematic Model as an improvement over the vectorial model developed earlier. The model solution described herein the most energy efficient means of cooling gears-that is, it requires the least pressure of pumping power to distribute the coolant on the tooth surface. Further, this nozzle orientation allows impingement to the root of the tooth if needed and provides the most cooling control when compared to into-mesh or out-of-mesh cooling. Keywords: Lubrication; Gears; Cooling; Oil jet flow; Gear Geometry; Mathematical models. (sdw)
