The standard’s title highlights two critical parameters: and Roll Measurement .
By enforcing tolerances on the roll variation rather than just the static profile, AGMA 2015-1-A01 directly controls Transmission Error. When a manufacturer certifies a gear to 2015-1-A01 Class A, they are essentially certifying that the gear will rotate smoothly, maintaining a constant velocity ratio. This reduces the need for expensive post-process "tuning" or lapping.
Here's a brief overview:
: It defines specific tolerance grades that correlate to the gear's intended performance. For example, a grade formerly known as "Q7" in the old 2000-A88 system might correspond to a Grade A7 in this newer standard.
Users of ANSI/AGMA 2015-1-A01 were expected to have a copy of the companion information sheet, , titled "Supplemental Tables for Accuracy Classification System – Tangential Measurement Tolerance Tables for Cylindrical Gears" . This sheet provided pre-calculated tolerance tables for all the accuracy grades to help users estimate tolerances quickly. agma 20151a01 pdf
The most direct question for many is, "Where can I find the PDF of this standard?" The answer, while straightforward, has significant implications.
The primary purpose of ANSI/AGMA 2015-1-A01 was to provide a mutually advantageous reference for both gear manufacturers and buyers, ensuring uniform tolerances and inspection procedures. It applied to unassembled, individual cylindrical involute gears. Specifically, the standard: This reduces the need for expensive post-process "tuning"

If 2015-1-A01 is the "rulebook" defining the tolerances , then AGMA 915-1-A02 is the "instruction manual" explaining the measurement methods . It constitutes a code of practice for inspecting cylindrical involute gears, detailing how to properly measure pitch, profile, helix, and other characteristics. The two documents work in tandem, and using measurement techniques not consistent with AGMA 915-1-A02 may invalidate the application of the tolerances specified in 2015-1-A01. Users of ANSI/AGMA 2015-1-A01 were expected to have
