Case Depth on Flanks of Gears for Helicopter Gaearboxes

Abstract

One of the most difficult and delicate operations during the manufacturing process of gears for helicopter gearboxes and aircraft gears is the heat treatment. Case hardened alloy steel of high quality are mainly used for aircraft gears. Not only a good structure in the case hardened tooth but also the surface hardness, the core hardness and case depth are very important for the load capacity of these gears.
