Scuffing Resistance and Starved Lubrication Behavior in Helicopter Gear Contacts: Dependence on Material, Surface Finish, and Novel Lubricants

A loss of lubrication event within rotorcraft drivetrain components leads to the rapid failure of contacting gear and bearing surfaces, thermal runaway, and catastrophic damage with possible loss of life. This article demonstrates that the scuffing failure of the gear and bearing surfaces can be del... View More
