The scope of AGMA 218.01 was specifically for external and internal involute spur and helical gear teeth operating on parallel axes. It built upon earlier standards, notably superseding , and became the reference point for gear rating throughout the 1980s and 1990s.
Surface pitting is a fatigue phenomenon caused by high contact stresses ( σcsigma sub c
AGMA 218.01 is a practical, technical standard focused on consistent gear measurement and inspection practices. It provides detailed procedures for instrumentation, setup, measurement, data reduction, uncertainty assessment, and reporting—ensuring that gear geometry is quantified consistently across industry stakeholders. For authoritative language, mandatory procedures, and exact acceptance criteria, obtain the official AGMA 218.01 document from AGMA or an authorized distributor. 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.
