Agma 218.01 !full!

The standard focuses on two primary failure modes: (surface durability) and bending strength . Its methodology relies on several critical rating factors: The design of spur and helical gearing

AGMA 218.01, published in 1982, established the foundational, yet now largely superseded, engineering method for calculating pitting resistance and bending strength in spur and helical involute gear teeth. It introduces critical factors for stress analysis, including overload and dynamic factors, and has been largely replaced by the ANSI/AGMA 2001 standard series.
