2019 AGMA Technical Committee revising several industry standards


Thanks to our many hardworking volunteer committee members, AGMA Technical Committees have had another successful year in 2019. After many years in the draft stage, two completely new documents were published in 2019, AGMA 944-A19, Mechanisms of Powder Metal PM Gear Failures, and ANSI/AGMA 1107-A19, Tolerance Specification for Form Milling Cutters. One adoption of an ISO Technical Report, AGMA ISO 18792-A19, Lubrication of industrial gear drives, was completed in 2019. Seven standards were revised to new editions in 2019:

  • ANSI/AGMA 1102-C19, Tolerance Specification for Gear Hobs.
  • ANSI/AGMA 2002-D19, Tooth Thickness and Backlash Measurement of Cylindrical Involute Gearing.
  • ANSI/AGMA 2003-D19, Rating the Pitting Resistance and Bending Strength of Generated Straight Bevel Zerol Bevel and Spiral Bevel Gear Teeth.
  • ANSI/AGMA 6001-F19, Design and Selection of Components for Enclosed Gear Drives.
  • ANSI/AGMA 6101-F19, Design and Selection of Components for Enclosed Gear Drives (Metric Edition).
  • ANSI/AGMA 6022-D19, Design Manual for Cylindrical Wormgearing.
  • ANSI/AGMA 6025-E19, Sound for Enclosed Helical Herringbone and Spiral Bevel Gear Drives.
  • And additionally, 11 documents were reaffirmed in 2019, which is the process of our committees reviewing the documents for continued relevance to the industry and technical accuracy:
  • AGMA 919-1-A14, Condition Monitoring and Diagnostics of Gear Units and Open Gears: Part 1 – Basics.
  • ANSI/AGMA 1003-H07, Tooth Proportions for Fine-Pitch Spur and Helical Gearing.
  • ANSI/AGMA 1010-F14, Appearance of Gear Teeth — Terminology of Wear and Failure.
  • ANSI/AGMA 2004-C08, Gear Materials Heat Treatment and Processing Manual.
  • ANSI/AGMA 2011-B14, Cylindrical Wormgearing Tolerance and Inspection Methods.
  • ANSI/AGMA 6011-J14, Specification for High Speed Helical Gear Units.
  • ANSI/AGMA 6022-C93, Design Manual for Cylindrical Wormgearing.
  • ANSI/AGMA 6033-C08, Materials for Marine Propulsion Gearing.
  • ANSI/AGMA 6133-C08, Materials for Propulsion Gearing (Metric Edition).
  • ANSI/AGMA 9004-B08, Flexible Couplings – Mass Elastic Properties and Other Characteristics.
  • ANSI/AGMA 1103-H07, Tooth Proportions for Fine-Pitch Spur and Helical Gearing (Metric Edition).

Like a well-designed machine that doesn’t break down, the expert knowledge, meticulous attention to detail and consensus-building skills of our volunteer members who work hard to develop the standards often go unnoticed in the background. The benefits of their work, however, are front and center to the gear industry and gear users every day. In 2020, a sampling of the work AGMA technical committees will be continuing is:

  • A new revision of ANSI/AGMA 2101, Fundamental Rating Factors and Calculation Methods for Involute Spur and Helical Gear Teeth. The revision is a complete rewrite of the 2004 edition to bring the standard up-to-date with the latest technology.
  • A new revision of AGMA 925, Effect of Lubrication on Gear Surface Distress. This will be the second revision of this information sheet that was first published in 2003.
  • A new revision of AGMA 911, Guidelines for Aerospace Gearing. The revision is a complete rewrite and reorganization of the 1994 edition to get the information sheet up-to-date with the latest technology.
  • A new revision of AGMA 923, Metallurgical Specifications for Steel Gearing, which will add a third grade to through-hardened gears and update the rest of the document to the latest industry practices. Information sheets such as this will help improve quality of raw materials by providing detailed guidelines on required specifications set by gear designers.
  • A completely new information sheet titled AGMA 943, Tolerances for Spur and Helical Racks, which should standardize the different practices used in the industry.
  • A new revision of ANSI/AGMA 1012, Gear Nomenclature, Definitions of Terms with Symbols, which will add more definitions and align better with international standards. Standards such as this help the industry by giving everyone the common language to define various gear elements and related attributes.
  • A new revision of ANSI/AGMA 1103, Tooth Proportions for Fine-Pitch Spur and Helical Gearing, to update formatting, clarify the language, and include the latest practices.

A full listing of AGMA technical committees, including a scope of their activities, can be found in the Technical Committees section of the AGMA website, www.agma.org.

For all the valuable contributions of our committee members to help the gear industry and gear users everywhere, we thank you!

Upcoming Education

Basic Training for Gear Manufacturing
April 13-17 | Chicago, Illinois

Learn the fundamentals of gear manufacturing in this hands-on course. Gain an understanding of gearing and nomenclature, principles of inspection, gear manufacturing methods, hobbing, and shaping. Using manual machines, develop a deeper breadth of perspective and understanding of the process and physics of making a gear as well as the ability to apply this knowledge in working with CNC equipment commonly in use.

Basic Gear Inspection for Operators
April 21-22 | Chicago, Illinois

Learn the common, current, and basics of the tools and techniques used to measure and inspect gears. There are four main categories by which a gear is evaluated and classified.  Gear design, manufacture, and inspection are based on numerical scale that defines gear quality.  The methodology to measure and the techniques required to quantify quality of a gear tooth form will be thoroughly investigated and explained.  It is often stated that quality cannot be inspected into the part; however, inspection can tell us what to do to correct many issues.

This class has been made possible with the generous donations of the AGMA Foundation.

Operator Hobbing & Shaper Cutting
May 12-13 | Chicago, Illinois

Learn and understand fundamentals of gear manufacturing. Acquire knowledge and understanding of gear nomenclature, hobbing and shaping of spur and helical gears, and splines. Learn and understand hobber and shaper machine set-up, as well as gear tooth element inspection. Understand the manufacturing process before gear tooth cutting, as well as post cutting processes. Apply concepts to further finishing processes, i.e. heat treat, gear tooth shaving and grinding and/or skiving. Gain knowledge to establish a solid foundation for all basic gear manufacturing.

This class has been made possible with the generous donations of the AGMA Foundation. 

Registration is Open!

Strategic Resources Network Meeting
May 27-29 | Charleston, South Carolina

The 2020 AGMA Strategic Resources Network (SRN) event has been designed for the next-generation manufacturing leaders. We are providing presentations that address the agile skills our current manufacturing environments require. Learn how to protect your company from cybersecurity threats, discuss what is keeping your peers up at night, and learn the latest discoveries from the AGMA Emerging Technology committees.

This year, attendees will also receive a four-hour special training course on contract negotiating. Join us in the unique environment of Charleston, South Carolina, network with your peers at a traditional low country boil, and tour the world-class Clemson University offshore wind turbine test facility.
