Documentation: A Challenge in Making Aerospace Gears

March 1, 2020
For years, Reliance Gear Corp. has manufactured gears for the aerospace industry. Located in Elmhurst, IL, Reliance has served as a Tier 2 or Tier 3 supplier. (Tier 1 suppliers work directly with the aerospace primes, the Boeings and Embraers of the world.) Like many gear shops, Reliance is certified under quality management standard ISO 9001. And its aerospace customers were satisfied with that certification. Until two years ago.

Oil-Off Characterization Method Using In-Situ Friction Measurement for Gears Operating Under Loss-of-Lubrication Conditions

June 1, 2019
The oil-off (also known as loss-of-lubrication or oil-out) performance evaluation of gears is of significant interest to the Department of Defense and various rotorcraft manufacturers, so that the aircraft can safely land in an accidental loss-of-lubricant situation. However, unlike typical gear failure modes such as pitting or bending fatigue where early detection is possible, gear failure in an oil-off situation is very rapid and likely catastrophic. Failures rapidly result in the loss of torque transmission and the inability to control the aircraft.

Oil-Out Endurance Under the Lens

January 1, 2017
Oil-out conditions, or conditions in which an aircraft is operating without any oil in its gearbox or transmission, are devastating for an aircraft's hardware. Even the sturdiest gears usually can't last 30 minutes under such conditions before they catastrophically fail, and the whole system usually follows shortly after. That doesn't leave pilots with a whole lot of time to find a suitable location to land in the case of an oil-out emergency.
