1 AGMA (Fall 2007)

Readers of our sister publication, Gear Technology, are perhaps more familiar with the American Gear Manufacturers Association (AGMA) than our PTE audience. Now more than 90 years old, AGMA continues to thrive as a global, relevant go-to resource and service provider—from metrology to tribology—for its more than 400 worldwide members. PTE put some questions regarding AGMA—now, and going forward—to AGMA president Joe T. Franklin, Jr.

2 ISO-AGMA Standards: Specific Sliding Defined (March 2017)

Does the definition of specific sliding mean the same between ISO 21771:2007 and AGMA 917-B97? In ISO, specific sliding is the ratio of the sliding speed to the speed of a transverse profile in the direction of the tangent to the profile. In AGMA, specific sliding is ratio of gear tooth sliding velocity to its rolling velocity.

3 AGMA--American Name, International Association (June 2010)

This letter to the editor from Joe T. Franklin, Jr., president of AGMA, first appeared in the May 2010 issue of Gear Technology.

4 AGMA in Full Support of Energy Initiative (February 2010)

Our politicians in Washington continue dithering over the Obama administration energy bill aimed at developing alternative, green sources of energy production. As a result, when this country will have a viable energy program in place is anyone’s guess, given the usual D.C. gridlock. And yet, Americans can take more than cold comfort in the fact that at least some government agencies—U.S. Department of Energy (DOE)—and the private sector—some major manufacturers—are doing more than their share of work in trying to harness our existing, fossil-based energy sources in such a way that they are used to their best efficiencies.

5 Made in China: A GM Engineer's First-Hand Perspective on the Chinese Roller Bearing Industry (October 2014)

Believe me when I tell you that — as a domestic automotive engineer — I bleed U.S. manufacturing. I have never lived more than 50 miles from Detroit,

6 Reducing Core Loss of Segmented Laminations (June 2009)

The recent trend toward using segmented laminations as a means to increase slot fill and facilitate automated fabrication of electric machines comes with a penalty of increased core loss at the segment joints.

7 Hands-Free Driving in the 1950s (April 2019)

Yes, the headline is correct: Autonomous vehicles are not a new idea. In fact, in the 1950s, handsfree driving so interested General Motors engineers that they designed a concept car for it. And in 1956, at its own auto show, the GM Motorama, the automaker unveiled the car, the Firebird II.

8 Gears, Fluid Power and Electric (February 2019)

The American Gear Manufacturers Association has evolved its trade show. What was formerly Gear Expo is now the Motion + Power Technology Expo (MPT Expo), an event intended to represent the entire motion and power transmission supply chain. As part of the expansion of the show’s scope, AGMA has partnered with the NFPA (National Fluid Power Association) to include a fluid power pavilion and additional educational sessions.

9 Get Ready, Get Set...Show (June 2019)

If you are involved in the acquisition of technology (whether your direct role is machine design, maintenance, purchasing or management), trade shows still provide one of the best ways to evaluate options, learn about the latest technology and find solutions to problems.

18 Embracing Change (December 2019)

Change can be daunting, nerve-wracking or even downright scary. But when we're faced with change in our lives, it's not the change itself we fear. It's the unknown elements that come with it. "You don't know what you don't know," a wise man once told me.

25 Shaking Hands in Indianapolis (August 2013)

Gear manufacturers set to talk with gear buyers at Gear Expo 2013.

26 Pre-Tension Thrust Bearings (December 2014)

What is the recommended method of gripping a spinning shaft (with up to 130 hp of rotational energy) to install pre-tension thrust bearings and conventional thrust bearings (load = hundreds of pounds) when the shaft cannot have any high points because it must pass through an area of tight clearances to assemble? Will snap rings still withstand the harsh vibration of this environment?

34 Documentation of Gearbox Reliability - An Upcoming Demand (June 2019)

The proof of the reliability of a gear drive is now an additional requirement. In Europe, the acceptance authorities for wind turbines are requesting a system reliability proof from gearbox manufacturers. The AGMA committee reviewing the AGMA 6006 standard for wind turbines is considering adding a chapter about design for reliability. However, reliability considerations are not new; NASA, for example, was in the 1980s using reliability concepts for gear drives.

You may well have already read the following Gear Expo description on the AGMA Website.

36 A Model for Shear Degradation of Lithium Soap Grease at Ambient Temperature (October 2017)

In this study the mechanical shear degradation of lithium-thickened grease was evaluated using an in-house-developed aging rig and a commercial rheometer. It was found that this grease loses its original consistency during aging and shows a two-phase aging behavior. In the first phase, primarily reorientation and breakage of the thickener network take place, resulting in a progressive drop in the grease's rheological properties. After this, the aging is dominated by the breakage of smaller fiber fragments and the grease degrades at a much slower rate.

37 Worm Gear Cutting (August 2016)

I have a fairly straightforward question about a worm gear segment. But as of yet, I haven’t gotten a straight answer from any of the gear job shops I’ve approached about this job. Is there a "traditional" gear cutting method that can produce a ~180 degree enveloping worm gear segment when a feature on the back of the part will interfere with a complete rotation of the part? Or am I left with only the option of 4- or 5-axis surfacing with a CNC mill? I have presented this part to several well-known gear shops in the U.S. without a straight answer on how the part can be made. Any help you could offer would be appreciated.

38 Michigan Eyes Investment at AWEA Small and Community Wind Conference (December 2009)

The first trade show dedicated specifically to small and community wind took place in Detroit, Michigan November 3–5. Denise Bode, American Wind Energy Association (AWEA) CEO, was pleased with the turnout for the event and the increasing potential for this segment of the wind energy market.

39 This Tattoo Machine is Off the Chain (August 2015)

Groan inducing, yes — but truer than the blue-soaked dermis layer of infamous ink fiend The Enigma (if you’re not familiar with the tattoo/sideshow icon, he’s basically an R-rated version of Papa Smurf who eats fire and twirls chainsaws). Though other altered individuals obviously operate on a much less extreme plane of body modification, there seems to be a definite link between the ink and the irregular.

40 Mix and Match Mechatronics (February 2016)

Mechatronics simplifies traditional engineering concepts across most industrial segments. By combining mechanical, electrical and computer technology into a single, integrated solution, products become systems that are more efficient, reduce operator error and cost less to manufacture.
