Agma 21801 Pdf [work] 【2026 Update】
st=WtKaKv1FmtKmKsJs sub t equals the fraction with numerator cap W sub t cap K sub a and denominator cap K sub v end-fraction the fraction with numerator 1 and denominator cap F m sub t end-fraction the fraction with numerator cap K sub m cap K sub s and denominator cap J end-fraction
Tooth breakage at the root fillet is catastrophic. AGMA 218.01 uses a modified version of the classic Lewis bending equation to determine root tensile stress ( σtsigma sub t Key variables in the bending formula include: Geometry Factor (
Understanding AGMA 218.01: The Foundation of Gear Rating Standards
The "AGMA method" introduced in 218.01 involves modifying the transmitted tangential load with several empirical and analytical factors to determine the allowable stress:
