Standards Projects – American Gear Manufacturers Association

Shape the gear standards of tomorrow, today!

Join over 300 of your gear industry colleagues by volunteering on AGMA standards projects.  The expert knowledge in AGMA’s current catalog of over 100 documents boosts American and worldwide business. AGMA standards projects are also your vehicle to participate in development of over 50 ISO gear standards, as many AGMA project working groups have a secondary function as technical advisory groups to ISO.

To join a standards project, all you need to do is be a member of AGMA and email us your interest at tech@agma.org.

Scroll down this page to see current standards projects. For more information on operations, click the link to see our How to Participate PowerPoint or click to read through our Chairperson’s Manual. For more information on ISO operations, click to see our ISO Intro PowerPoint. After volunteering you’ll be able to see all the last drafts, minutes and development documents on the AGMA Document Portal.

AGMA 6011-KXX, Specification for High Speed Helical Gear Units

Project Start Date: June 2022

Project End Date (est.): June 2025

Project Type: Revision

Project Leader: John Amendola, Artec Machine

Current Project Status: The document is in the Review and Comment stage. Comment review will begin in April 2024.

Scope of project:

Update to assess compatibility with proposed changes to following documents:

AGMA 923: Metallurgical Specifications for Steel Gearing
AGMA 925, Effect of Tribology and Lubrication of Gear Surface Distress

API Standard 613-6: Special-purpose Gears for Petroleum, Chemical, and Gas Industry Services

The entire document will be open for review, but the focus will be on the following topics:

Review scuffing criteria and micropitting criteria;
Review stress numbers;
Review specific loads on bearings;
Review the effect of changes in retained austenite in service Clause 4.8 global change for term gear casing to gear housing;
Pitting should be differentiated between micro and macro pitting Clause 4.9 Bearing;
Review Clause 5 Rating of Gears;
Review use of stress numbers Clause 5.5 Update references to AGMA 923 Clause 5.7 Scuffing resistance;
Review (relative to new 925-B22) Clause 6 Lubrication;
Review (after completion of 955-AXX) Clause 6.1 ;
Expand discussion on micropitting (see 925-B22) Clause B.2 Scuffing considerations;
Apply plv limits for using Cw in the F(load) equation Appendix F needs to be revised (After completion of AGMA 923); and
Update/clarify text in regard to the request for interpretation resolved in 2019, and the email question received 8-11- 2021.

Note: One reaffirmation occurred in 2019 with no comments submitted

AGMA 9000-EXX, Flexible Couplings – Potential Unbalance and Mass Elastic Properties

Project Start Date: May 2022

Project End Date (est.): June 2024

Project Type: Revision and combination of AGMA 9000 and AGMA 9004

Project Leader: Lisa Riggs, Regal Rexnord Corp.

Current Project Status: The document is in the Review and Comment stage. Comment review will begin in Spring 2024.

Scope of project:

Combine the following into one Standard:

ANSI/AGMA 9000-D11, Flexible Couplings – Potential Unbalance Classification
ANSI/AGMA 9004-B08, Flexible Couplings – Mass Elastic Properties and Other Characteristics
And their metric equivalents ANSI/AGMA 9110-A11 and ANSI/AGMA 9104-A06

Combine standards as noted above while incorporating comments received from previous reaffirmations. New combined standard title to be: Flexible Couplings – Potential Unbalance and Mass Elastic Properties

AGMA 919-2-AXX, Condition Monitoring and Diagnostics of Gear Units and Open Gears: Part II – Applications and Advanced Analyses

Project Start Date: May 2021

Project End Date (est.): January 2025

Project Type: New Document

Project Leader: Steve Rogan, Artec Machine

Current Project Status: The document is in the Working Draft stage. Sections in the main body of have been assigned but are still being reviewed and edited. The estimate to go to Committee Comment is July 2024.

Scope of project:

This information sheet is a continuation of AGMA 919-1, that will discuss in greater detail the application of vibration and acoustic techniques for condition monitoring, instrumentation and methods for diagnostics of industrial gear units and open gearing. Guidance will be provided on how to establish baseline data, analyze trends, set action limits, run diagnostics, and define action plan.

This document will have more examples / practical applications than other current AGMA and ISO documents on this subject.
This document will point the reader to all the other different documents on condition monitoring, and if no other document covers the subject will include it.

AGMA 926-DXX, Recommended Practice for Carburized Aerospace Gearing

Project Start Date: October 2021

Project End Date (est.): October 2025

Project Type: Revision

Project Leader: Scott Davidson, Boeing Rotorcraft – Philadelphia

Current Project Status: The project is in the Working Draft stage, and on track to go to the Review and Comment stage by April of 2024. All sections of the document have been assigned to members for review and possible editing. The group works through completed assignments at meetings.

Scope of project:

Update the complete information sheet to incorporate newer materials and heat treatment methods in use in aerospace gearing.

Current coverage is for 9310 and similar materials, however examples are limited to atmospheric carburized 9310. The goal is to capture material information that represents the current state of aerospace gear material selection and the associated processing requirements. Update with alloy examples from AGMA 911 and AGMA 937 as well as possible newer alloys.

This update will include such things as:

Pre-oxidation
Sub critical anneal
Low pressure carburizing
High pressure quenching
Banding
Cleanliness
Testing acceptance criteria
Definitions
Stress relief

Due to the unique requirements of aerospace gearing for many of these materials, the processing requirements are not well defined elsewhere. Thus, this is an opportunity for AGMA to fill a technical information gap.

This document will only cover carburized aerospace gearing. Other heat treatment methods do not have unique aerospace requirements and are covered by other documents.

AGMA 2101-EXX, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth (Metric Edition)

Current Project Status: Commenting closes 1-12-2024. After comments are resolved it will be published.

ANSI/AGMA 1010-F14, Appearance of Gear Teeth – Terminology of Wear and Failure.

This nomenclature standard identifies and describes the classes of common gear failures and illustrates degrees of deterioration. The current, sixth edition was published in 2014 with 89 detailed color figures showing gear failures over 81 pages.

Proposed updates for the next edition include:

aligning nomenclature with ISO 10825 and ISO 15243;
reorganizing clause numbers;
and adding additional failure modes, including plastic and powder metal gear failure modes.

AGMA 930-A05, Calculated Bending Load Capacity of Powder Metallurgy External Spur Gears.

With 78 pages, this information sheet describes a procedure for calculating the load capacity of a pair of powder metallurgy external spur gears based on tooth bending strength.

Two types of loading are considered:

1) repeated loading over many cycles;
2) occasional peak loading.

Proposed updates for the next edition include:

aligning rating methods with the soon to be published new edition of AGMA 2101 and MPIF 35;
adding helical gear rating, adding pitting resistance rating;
adding internal gear rating;
and updating dynamic factors.
