By Justin Sikorski, AGMA Staff Engineer
Over the course of the past year, AGMA technical committees have been hard at work producing the standards and information sheets that help the gear industry operate effectively and efficiently. In 2014, AGMA published new revisions of three standards, a brand new information sheet, and adopted an ISO standard. The development of these documents would not have been possible without the dedicated support and expertise that the AGMA membership provides to the association. The staff of the AGMA Technical Division thanks each individual, and their companies, for all of this hard work.
AGMA has always relied on the dedicated support and expertise of our membership to develop the technical standards and information sheets that continually move the gear industry forward. However, the benefits of participation on a technical committee are not only enjoyed by the readers of the published documents. The members of AGMA technical committees are the authors of the standards that the gear industry follows. Technical committee members, and their companies, find this opportunity very beneficial professionally and intellectually. Each member of a technical committee has the opportunity to interact with, and learn from, their counterparts from all around the gear industry, as well as, gain an intimate understanding of the information contained within the document being developed. The majority of technical committee meetings take place via web conferences allowing participants to attend the meetings without significant disruptions to their day-to-day responsibilities.
The following is a list of documents that AGMA technical committees published in 2014:
• ANSI/AGMA 1010-F14, Appearance of Gear Teeth – Terminology of Wear and Failure;
• ANSI/AGMA 6011-J14, Specification for High Speed Helical Gear Units;
• ANSI/AGMA 2011-B14, Cylindrical Wormgearing Tolerance and Inspection Methods;
• ANSI/AGMA ISO 1328-1-B14, Cylindrical Gears – ISO System of Flank Tolerance Classification – Part 1: Definitions and Allowable Values of Deviations Relevant to Flanks of Gear Teeth;
• AGMA 919-1-A14, Condition Monitoring and Diagnostics of Gear Units and
Open Gears: Part 1 – Basics.
In addition to the standards and information sheets, AGMA has also released new versions of two of its most popular software offerings, Gear Rating Suite v. 3.1 and Bevel Gear Rating Suite v. 1.3. The new versions of the software include updates to the latest applicable standards as well as fixes of several bugs found in previous versions.
Looking forward to 2015, there are several exciting projects that are going to get underway. The first is a revision of AGMA 925-A03, Effect of Lubrication on Gear Surface Distress. The current version AGMA 925 provides methods for calculating elastohydrodynamic lubrication (EHL) film thickness and contact temperature. It also provides methods for predicting the probability of unwanted surface distresses such as wear and scuffing. As part of the revision, the committee is planning to update these methods and will attempt to develop a method for predicting the probability of micropitting.
Another project that will be getting underway in the new year is the second part of AGMA 919. Part two of AGMA 919 will look at the application of diagnostic tools and instrumentation to analyze vibration, acoustics, motor current signature, and lubrication. The information sheet will also discuss the methods for condition monitoring, performing diagnostics, monitoring temperature, establishing baseline data for trend analysis, and non-destructive testing of in-service gear units and open gearing.
The Metallurgy and Materials Committee will also be starting a revision of AGMA 923-B05, Metallurgical Specifications for Steel Gearing. This document identifies metallurgical quality characteristics which are important to the performance of steel gearing, and performance levels of gearing by heat treatment method and grade number. For each heat treatment method and AGMA grade number, acceptance criteria are given for the various metallurgical characteristics identified in this document. With this revision, the committee is looking to ensure the document’s continued compatibility with the latest industry 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.

Complete Champion Leadership: How Fast Can You Get Fast?
Derek Daly, international racing champion, best-selling author, and television’s face of motor sports
If the speed of doing business will continue to increase in the next 10 years, ask yourself, how fast can we get fast? Daly will demonstrate that “fast” is having the right people in the right places doing the right things, but more importantly, it is removing the speed bumps that slow them down.
Daly, and Irish driving legend, is the epitome of the complete champion. From the victory circle to the announcer’s desk, the Hall of Fame Race Car Driver and network television anchor has spent nearly three decades as the face of the motorsport world. Born and raised in Dublin, Ireland, Daly’s career path was set at the age of 12 when he attended his first auto race.
Daly has shared these timeless speed-related business principles with a diverse group of companies in the private sector and the U.S. government. They have all shared in Daly’s complete championship model to motivate, inspire and enlighten their teams.
Rethink, and Thrive
Michael Rogers, author and futurist-in-residence, The New York Times
More and more of how we work is moving into the virtual world — our work process, how we collaborate with partners and how we manage our employees. Virtual organization, global connectivity, smart objects, cloud-based intelligence all will shape the rest of this decade. And the next generation of workers will bring even more digital skills and demands. What will the work and production environment of 2020 look like? What steps should we take now to make sure our businesses move in the right direction?
Rogers is a best-selling author, technology pioneer and futurist. He regularly speaks to audiences worldwide at Fortune 500 companies about implementing the future in useful ways. Rogers earned his degree in physics and worked in the technology field before branching off as a futurist.
Looking at the Reshoring Initiative
Harry Moser, President, The Reshoring Initiative
The increasing advantages of producing in America for the North American market are driving companies to reevaluate offshoring. A high percentage of the jobs reshored are in gear and bearing intense mechanical product industries such as appliances, machinery and automotive components. During this session, you will be exposed to the statistics regarding the current trends. Learn the what, where, and the why of reshoring and how it can be applied to your company. Harry will provide tools for comparing the economics of offshoring to reshoring.
Harry is in a unique position to provide advice on this subject. Prior to starting the Reshoring Initiative, he worked for GF AgieCharmilles, starting as President in 1985 and retiring in 2010 as Chairman Emeritus. He now devotes his time fully to the Reshoring Initiative, whose goal is to bring manufacturing jobs back to the United States.
Economic and Market Outlook – Getting Old or Starting Fresh?
James P. Meil, Principal, Industry Analysis, ACT Research
By the summer of 2015, the economic recovery and expansion will be six years old. However, its slow pace leads some observers to think that even now, we are still in a lingering recession. The statistics show that it has been the slowest, least dynamic economic rebound of the post-1945 experience. Jim Meil returns to answer the most important question – will 2015 and 2016 bring a change, or more of the same?
Returning AGMA/ABMA Annual Meeting attendees will remember Meil’s previous presentations he gave as the Chief Economist from Eaton Corporation. After retiring from Eaton, Jim joined ACT Research in 2014 and now will continue to share his views on the U.S. economy. He will add insights to the domestic and international markets and discuss how the energy environment and exchange rates will affect the key machinery market outlook overall.
