Agma 21801 — Pdf

The AGMA 218.01 (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 While it has been technically withdrawn and replaced by newer standards like ANSI/AGMA 2001-D04, it remains a critical reference for legacy equipment and understanding the evolution of gear design.

2.2 Noise Rating Classes

| Class | Description | Typical Application |
|-------|-------------|---------------------|
| A | Highest quality | Precision machine tools, luxury vehicles |
| B | Commercial quality | General industrial gearboxes |
| C | Standard quality | Agricultural machinery |
| D | Lowest quality | Non-critical, low-speed drives | agma 21801 pdf

• Pitch deviation (single and cumulative)
• Profile deviation (involute form error)
• Lead deviation (helix alignment)
• Runout (eccentricity of the gear)

• AGMA Q5-Q7: General purpose industrial gearing, standard machinery.
• AGMA Q8-Q10: High-speed gearing, turbines, and precision machine tools.
• AGMA Q11-Q15: Instrumentation, aerospace, and metrology masters.
