Gear noise is a critical quality indicator for industrial drives, automotive transmissions, and wind turbines. Before ISO harmonization, the American Gear Manufacturers Association (AGMA) published , titled “Sound Measurement and Sound Power Levels of Enclosed Gear Drives.” The standard provided a repeatable method for measuring airborne sound and established four sound-level classes. Although superseded, many legacy designs and maintenance manuals still reference AGMA 218.01, making its understanding necessary.

AGMA 218.01 (now largely superseded by AGMA 910 series and ISO 6336) focuses on: agma 21801 pdf

AGMA 21801 provides tables of maximum permitted deviations for each grade and module (tooth size) range. Your instrument's software (e.g., Gleason Axiom, Klingelnberg Gear Analyzer) may already include AGMA 21801 as a selectable standard. Gear noise is a critical quality indicator for

The (published in 1982) is a foundational historical standard titled Standard for Rating the Pitting Resistance and Bending Strength of Spur and Helical Involute Gear Teeth . While it has been technically withdrawn and replaced by newer standards like ANSI/AGMA 2001-D04 , it remains a critical reference for legacy equipment and understanding the evolution of gear design.
