The is a non-profit organization founded in 1916. It develops technical standards for the gear industry, covering everything from design, rating, and lubrication to testing and inspection. As an American National Standards Institute (ANSI)-accredited standards developer, AGMA's publications form the backbone of reliable power transmission engineering in North America and beyond.

The standard focuses primarily on preventing two destructive failure modes in gear teeth: Pitting Resistance (Surface Fatigue)

Modern standards include refined factors for dynamic loads ( Kvcap K sub v ) and load distribution ( Kmcap K sub m ) based on better manufacturing capabilities. agma 21801 pdf

The standard introduced a numerical classification system ranging from lower numbers (coarser accuracy) to higher numbers (finer accuracy). This allowed engineers to specify exactly what level of quality was required for a specific application. For instance, a gear used in an agricultural tractor would not require the same tolerance level as a gear used in a jet engine. AGMA 218.01 provided the empirical data to make these distinctions clear, reducing costs by preventing over-engineering and preventing failures by ensuring sufficient precision.

Newer standards introduced much stricter definitions for material cleanliness, heat treatment processes, and grade classifications (Grade 1, Grade 2, and Grade 3 steels).

Calculated using modified Lewis equations to prevent tooth root breakage. Historical Context & Replacement The standard focuses primarily on preventing two destructive

AGMA 218.01 is a historical 1982 standard for gear rating that was later superseded by ANSI/AGMA 2001-B88, though its foundational formulas remain relevant. While no longer sold officially, the document can be found through various technical repositories and document-sharing sites.
