ANSI/AGMA 2015-1-A01
is a critical engineering standard titled "Accuracy Classification System - Tangential Measurements for Cylindrical Gears." Approved in August 2002, it established a modern framework for classifying the accuracy of spur and helical gears based on tangential (individual flank) measurements. 1. Scope and Core Purpose
- Fine pitch (20-200 DP): 0.005" to 0.015" minimum.
- Coarse pitch (<20 DP): 0.010" to 0.030".
Tangential Space Thickness
- Full title: Accuracy Classification System – Tangential Measurements for Cylindrical Gears
- Published: 2001 (the “A01” likely refers to the 2001 revision, ANSI-approved)
- Scope: Defines a system for gear accuracy classification based on tangential (over-pin or ball) measurements, often used for splines and fine-pitch gears.
- Status: Superseded by newer versions (e.g., AGMA 2015–2–A06 or ANSI/AGMA 2015–1–A01).
In summary, AGMA 2015-1-A01 is more than just a list of tolerances. It is a comprehensive framework that defines modern gear quality. By adopting these grades, manufacturers can guarantee interchangeability and performance in an increasingly demanding global market. agma 20151a01 pdf
