- Learn about and study various technical subjects—related to gear design, manufacture, and operation—that are important to career development and your company’s future.
Details
- Willingness to actively participate is the only requirement for membership on a technical committee or working group.
- The technical committee structure has two levels: Committee and Working Group.
- Committee: a permanent, overarching committee that manages ISO TAG responses, project Working Groups, and document reaffirmations; also responds to requests for interpretation (RFIs).
- Working Group: a temporary group formed within a committee that creates a new document or works on a revision. The name of the Working Group consists of the document number designation). This group only works on one project at a time, and the Working Group is dissolved at completion of the project.
- A Working Group member is a representative of a member company that regularly attends meetings and accepts and performs work assignments as assigned by the Project Leader. Only active members will be considered in determining a quorum and have a vote on committee activities.
- Meetings are either held face-to-face or via web conferencing. Face-to-face meetings are generally held over the course of two days at an easily accessible location or a member’s facility. Web conferences are generally two hours long and usually start at either 10:00 a.m. or 2:00 p.m. U.S. Eastern time. Active projects typically hold meetings every other month.

AGMA 926-DXX, Recommended Practice for Carburized Aerospace Gearing
Committee: Aerospace
Project Type: Revision
Project Leader: Scott Davidson, Boeing Rotorcraft – Philadelphia
AGMA Staff Liaison: Todd Praneis
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 936-AXX, Calculated Bending Load Capacity and Pitting Resistance of Powder Metallurgy, PM, External Spur and Helical Gears
Committee: Cylindrical Gear Rating
Project Type: New Document
Project Leader: Ernie Reiter, Web Gear Services, Ltd
AGMA Staff Liaison: Todd Praneis
Project Status: Working draft stage. A working group has been formed to start the revision process. Major topics for revision have been identified and the WG is gathering input for changes.
Scope of Project: AGMA 930-A05 is an information sheet that details a calculation method for PM External Spur Gear bending load capacity. This information sheet has now shown through use to have the following issues:
- It is too conservative for the rating of PM gears.
- Helical gears are not covered by this information sheet but need to be added.
- Internal gears need to be added to the rating method potentially using the ISO method for J factor calculation.
- Add J factor calculations for circular arc root fillets for external gears and refer to AGMA 908 for trochoidal root fillets. Protuberance will also be included.
- AGMA 2101 has been updated to revision EXX and this document should be adjusted to be more in line with AGMA 2101 in some basic principles.
- The method should be standardized with the intent of revising the information sheet.
- As part of the development of this document, consideration should be given if pitting can be included in the ratings at this time.
- Additive manufactured gears will not be included.
