: The standard includes formulas to calculate the surface durability of gear teeth, helping designers prevent premature failure from contact stress. agma 21801 pdf

A note on terminology: avoid confusion with "(21801) Ančerl", an asteroid, which is an entirely unrelated celestial body. ): Adjusts the rating based on the required

The American Gear Manufacturers Association sells current standards and maintains historical archives through their official portal or authorized distributors like Techstreet and IHS Markit. 2023 . However

AGMA 218.01 introduced standardized calculation methodologies where actual calculated stresses must be lower than the allowable material stresses modified by specific application parameters. 1. Pitting Resistance (Contact Stress) Contact stress ( σcsigma sub c

AGMA 218.01 splits gear failure analysis into two core mathematical pillars: contact (surface) stress and bending (root) stress. Both formulas begin with a basic theoretical load and systematically modify it using operational multipliers. Bending Stress Equation ( σtsigma sub t

As of 2026, AGMA 218.01 is a . This means the AGMA no longer sells it, and it is not considered a current or active specification for new designs. The standard was withdrawn and superseded on November 6, 2023 . However, this does not mean the information is obsolete. The technical content has been refined and redistributed into the active standards mentioned above.
