Overview
Selecting the appropriate lubricant is a critical step in gear design. When properly selected and applied, gear lubricants reduce friction and wear, help to prevent corrosion, reduce operating noise, improve heat transfer and facilitate removal of abrasive wear particles from the contact areas of the gear tooth surfaces.
In this course, the student will study the lubricants that are used to protect the various types of gears that are used in commercial applications. The course will cover Chapter 9, "Gears" in the US Army Corps of Engineers document EM 1110-2-1424, "Lubricants and Hydraulic Fluids".
The student must take a multiple-choice quiz consisting of ten questions at the end of this course to obtain PDH credits.
