Fundamentals of Bevel Gear Hard Cutting
The article "Fundamentals of Bevel Gear Hard Cutting" appeared in the November/December 1990 issue of Gear Technology.
Some years back, most spiral bevel gear sets were produced as cut, case hardened, and lapped. The case hardening process most frequently used was and is case carburizing. Many large gears were flame hardened, nitrided, or through hardened (hardness around 300 BHN) using medium carbon alloy steels, such as 4140, to avoid higher distortions related to the carburizing and hardening process.
