Scuffing Resistance and Starved Lubrication Behavior in Helicopter Gear Steels Coated with Nanocomposite Surface Coatings with and without a Hard Sublayer

Autor: Stephen Berkebile, Andras L. Korenyi-Both, Nikhil Murthy, Mark R. Riggs

Publikováno v: Tribology Transactions. 63:610-620

Helicopter drivetrain components depend on oil lubrication to maintain elastohydrodynamic lubrication between sliding surfaces and are susceptible to a loss of lubrication event. A loss of lubricat...

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

Autor: Mark R. Riggs, Stephen Berkebile, Nikhil K. Murthy

Publikováno v: Tribology Transactions. 60:932-941

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 f

Ball-on-DiscTribometers Protocol Development: Loss of Lubrication Evaluation

Autor: Nikhil Murthy, Stephen Berkebile, Mark R Riggs

Loss of lubrication (LoL) protocol development consists of determining the proper parameters to simulate relevant gear-and-bearing contact conditions under starved lubrication. The goal is to evaluate the performance of materials and lubricants and u

Simulating Army-Relevant Spur Gear Contacts with a Ball-on-Disc Tribometer

Autor: Stephen Berkebile, Mark R Riggs, Adrian A. Hood, Brian Dykas

Investigating tribological properties of gear materials, surface finishes, coatings, and lubricants in high-speed and high-load contact conditions is integral to the advancement of drivetrain technology. A focused simulation of gear contacts can be a
