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

The , titled "Standard for Rating the Pitting Resistance and Bending Strength of Spur and Helical Involute Gear Teeth," is one of the most influential legacy documents in mechanical power transmission. Published by the American Gear Manufacturers Association (AGMA) in December 1982, it served as the foundational bedrock for modern gear stress calculations and design criteria globally.

Many proprietary and commercial Gear Design Software suites still include AGMA 218.01 as a legacy calculation module. Developers need the PDF to audit code correctness. agma 21801 pdf

The standard, titled "Standard for Rating the Pitting Resistance and Bending Strength of Spur and Helical Involute Gear Teeth," is a foundational document used to determine the load-carrying capacity of gears. Although it has been superseded by newer standards like ANSI/AGMA 2001 , it remains a significant reference for gear engineers for calculating tooth stress and surface durability.

Another authorized reseller. Often used by large engineering firms with subscription accounts. A note on terminology: avoid confusion with "(21801)

The bending stress equation determines the structural integrity of the tooth root. The fundamental formula calculates the bending stress number (

Even though AGMA 218.01 is technically considered a "withdrawn" standard, it remains highly relevant in industry. Many proprietary and commercial Gear Design Software suites

AGMA 21801 is especially known for its integration with (e.g., the Gleason 275G or Klingelnberg P-series). The standard defines how to measure center distance variation and composite tooth deviation.

AGMA 218.01 is a technical standard published by the American Gear Manufacturers Association (AGMA). It provides recommended practices and procedures related to gear measurement, inspection, or design (depending on the specific topic covered in the 218 series). Standards like AGMA 218.01 are used by gear designers, manufacturing engineers, quality inspectors, and researchers to ensure consistent, repeatable assessment of gear geometry and performance across industry and research contexts.

Calculated using Hertzian contact stress formulas to prevent surface fatigue.

The primary, direct replacement for the rating methodology of AGMA 218.01 is the widely used:
