A review of "A Nation on Borrowed Time," a book by Joe Arvin and Scott Newton about the decline of America's ability to create wealth through manufacturing, and its effect on the overall economy.
Machinery's Handbook 25 by Erik Oberg, Franklin D. Jones, Holbrook L. Horton & Henry H. Ryffel, Reobert E. Green, ed., Industrial Press Inc., New York, NY, 1996 ISBA 0-8311-2424-5, $75.00 (Large Print Version, $95.00).
This textbook, written for college level engineering students, gives a basic grounding in the complexities of product liability law. It also provides useful information to those of us involved in the manufacturing of gears and gear systems in that the fundamental concepts apply to all types of manufacturers.
This book is written for those among us, with or without a technical background, who have an occasional need to use, purchase or specify gears. The author assumes an audience that is not made up of experienced gear designers, but of people who do need to have a basic understanding of the criteria used by the designer. The subjects covered include not only the gears themselves, but their manufacturing methods, the systems that contain them and the terms used to describe them.
Review of "Gigacycle Fatigue in Mechanical Practice," by Claude Bathias and Paul C. Paris
Gearing is a self-training course for teaching the basic fundamentals of gears and gearing to those totally unfamiliar with the subject.
Review of several new books for gear engineers.
When I was new to gear engineering, I found the array of gear literature scare, and the information scattered and conflicting. After investigating the materials available, I set the goal of creating an annotated listing of the references. There are many valuable resources, but for this article I have selected ten of the best. These references, in my opinion, are the most useful, and cover the scope while minimizing redundancy.
How you can get involved in a grassroots movement to save American manufacturing--and the American economy.
Booth previews from exhibitors showing products and services for the gear industry.
The selection of the proper steel for a given gear application is dependent on many factors. This paper discusses the many aspects related to material, design, manufacture, and application variables. The results of several studies on the optimization of alloy design for gas- and plasma- carburization processing and reviewed.
Except for higher-end gear applications found in automotive and aerospace transmissions, for example, high-performance, sintered-steel gears match wrought-steel gears in strength and geometrical quality. The enhanced P/M performance is due largely to advances in powder metallurgy over last two decades, such as selective surface densification, new materials and lubricants for high density and warm-die pressing. This paper is a review of the results of a decade of research and development of high- performance, sintered-steel gear prototypes.
Previews of manufacturing technology related to gears that will be on display at IMTS 2012.
In Part I differences in pitting ratings between AGMA 218, the draft ISO standard 6336, and BS 436:1986 were examined. In this part bending strength ratings are compared. All the standards base the bending strength on the Lewis equation; the ratings differ in the use and number of modification factors. A comprehensive design survey is carried out to examine practical differences between the rating methods presented in the standards, and the results are shown in graphical form.
This paper reviews the necessity for detailed specification, design and manufacture to achieve required performance in service. The precise definition of duty rating and a thorough understanding of the environmental conditions, whether it is in a marine or industrial application, is required to predict reliable performance of a gearbox through its service life. A case study relating to complex marine gears and other general practice is presented to review the techniques used by Allen Gears to design and develop a gearbox that integrates with the requirements of the whole machinery installation. Allen Gears has considerable experience in the design of a variety of industrial and marine gears(Ref. 1,2).
India is rapidly turning into a global manufacturing hub, thanks to the country’s manufacturing and engineering capabilities, vast pool of skilled expertise and its size. These qualities offer it a strategic advantage for the manufacturing segment. A large number of international companies in varied segments have already set up a manufacturing base in India and others are following suit. It only makes sense to bring this industry segment together under one roof to discuss the current trends and technology prevalent to the marketplace. IPTEX 2012 is scheduled from February 9–11, 2012 at the Bombay Exhibition Center in Mumbai, India.
The organizers of Gear Expo 2007 promise to combine the most popular features of shows past with some innovations for this year’s attendees. By the time the show closes on October 10, the association hopes its targeted 175 exhibitors walk away with new insights leading to profitability and renewed contacts.
Sure, Gear Expo undoubtedly has a ton to offer attendees in education, research and networking alone, but what really draws the crowd in are the physical products and technology on display from exhibitors. Otherwise it would just be another technical meeting or social reception—and AGMA could save a few bucks on space to say the least.
Here's our editors' look at some of the best new technologies for gear manufacturers that will be on display at IMTS 2010.
There’s a bustle of activity as exhibitors prepare for America’s most significant manufacturing trade show. The red carpets are ready, the lights are being tested, and the crowds are gathering with anticipation. Amid the excitement, Gear Technology has managed to sneak under the usher’s ropes to provide you with this advance look at some of the gear-related products and technologies that will be featured at IMTS 2004.
Our coverage of the gear-related booths at IMTS continues from last issue.
Here are some of the new products and technologies available to attendees at Heat Treat 2011.
There will be plenty of time to talk shop, learn about the latest educational and research endeavors and network with peers. But the real reason the gear industry comes together every two years is to see all the new products and technology offerings.
Can a gear profile generated by the hobbing method be an ideal involute? In strictly theoretical terms - no, but in practicality - yes. A gear profile generated by the hobbing method is an approximation of the involute curve. Let's review a classic example of an approximation.
Forty of Gear Technology's pre-show and show issue advertisers will be exhibiting a wide range of goods and services at AGMA's Gear Expo '93. The exhibition will be held October 10-13 at Cobo Conference & Exhibition Center in Detroit, MI. Below is an alphabetical listing of these advertisers and a preview of what can be seen at their booths.
In a very general sense, increasing the hardness of a steel gear increases the strength of the gear. However, for each process there is a limit to its effectiveness. This article contains background information on each of the processes covered. In each section what is desired and what is achievable is discussed. Typical processes are presented along with comments on variables which affect the result. By reviewing the capabilities and processes, it is possible to determine the limits to each process.
This is a three-part article explaining the principles of gear lubrication. It reviews current knowledge of the field of gear tribology and is intended for both gear designers and gear operators. Part 1 classifies gear tooth failures into five modes and explains the factors that a gear designer and operator must consider to avoid gear failures. It defines the nomenclature and gives a list of references for those interested in further research. It also contains an in-depth discussion of the gear tooth failure modes that are influenced by lubrication and gives methods for preventing gear tooth failures.
For heat treatment of tool and alloy steels, the end-user has a wide range of basic types of heat treating equipment to choose from. This article reviews them and details the criteria that must be considered in selecting equipment for a specific application. In making this choice, the most important criterion must be the quality of the tool or part after processing.
Gear Expo '95, held in Indianapolis, November 12-15, 1995, closed to rave reviews from both the attenders and the exhibitors. Traffic for the show was well up from 1993, with a total of about 4,000 visitors during the 3 1/2 day exhibition. One hundred thirty-two companies from all over the U.S. and as far away as India and The People's Republic of China displayed their wares.
Preview of some of the exhibits relevant to gear manufacturing at the upcoming EMO 2013.
The merits of CBN physical characteristics over conventional aluminum oxide abrasives in grinding performance are reviewed. Improved surface integrity and consistency in drive train products can be achieved by the high removal rate of the CBN grinding process. The influence of CBN wheel surface conditioning procedure on grinding performance is also discussed.
Before we get into projections and prognostications about the future, let’s take a minute to review 2012. For many in the gear industry, the year was better than expected. Some manufacturers had a very successful year leading up to an even more successful manufacturing trade show (IMTS 2012). Others were searching for more business, hoping that the general state of the economy wouldn’t make things worse. In some cases, it did.
Gear Expo 2013 product preview features a look at many of the key booths you won't want to miss.
Sometimes in the pressure to meet deadlines and handle the Crisis of the Day, we lose sight of the forest for the trees. As a partial cure for this syndrome, I recently reviewed the six interviews with gear industry leaders that have appeared in our pages during the last year, trying to get a grasp of a larger picture. It struck me with renewed force how six men, each with a lifetime of experience in this business, see the gear industry forest the same way.
In earlier studies, surface roughness has been shown to have a significant influence on gear pitting life. This paper discusses how high surface roughness introduces a wear mechanism that delays the formation of pits. Accompanied by a full-page technical review.
Booth previews in the Gear Pavilion and beyond.
Preview of Gear Expo, with information on AGMA's fall technical meeting and the city of Detroit.
I just finished conducting annual reviews with our employees. They, we--all of us--get our paychecks from our customers.
Publisher Michael Goldstein had a chance to preview Ken Burns' documentary series about WWII, and he shares some of his thoughts.
This paper initially defines bias error—the “twisted tooth phenomenon.” Using illustrations, we explain that bias error is a by-product of applying conventional, radial crowning methods to produced crowned leads on helical gears. The methods considered are gears that are finished, shaped, shaved, form and generated ground. The paper explains why bias error occurs in these methods and offers techniques used to limit/eliminate bias error. Sometimes, there may be a possibility to apply two methods to eliminate bias error. In those cases, the pros/cons of these methods will be reviewed.
This article reviews mathematical models for individual components associated with power losses, such as windage, churning, sliding and rolling friction losses.
A trial test of the calibration procedures outlined in ISO 18653—Gears: Evaluation of Instruments for the Measurement of Individual Gears, shows that the results are reasonable, but a minor change to the uncertainty formula is recommended. Gear measuring machine calibration methods are reviewed. The benefits of using workpiece-like artifacts are discussed, and a procedure for implementing the standard in the workplace is presented. Problems with applying the standard to large gear measuring machines are considered and some recommendations offered.
In designing involute gear teeth, it is essential that the fundamental properties of the involute curve be clearly understood. A review of "the Fundamental Laws of the Involute Curve" found in last issue will help in this respect. It has previously been shown that the involute curve has its origin at the base circle. Its length, however, may be anything from zero at the origin or starting point on to infinity. The problem, therefore, in designing gear teeth, is to select that portion of the involute, which will best meet all requirements.
A study of AGMA 218, the draft ISO standard 6336, and BS 436: 1986 methods for rating gear tooth strength and surface durability for metallic spur and helical gears is presented. A comparison of the standards mainly focuses on fundamental formulae and influence factors, such as the load distribution factor, geometry factor, and others. No attempt is made to qualify or judge the standards other than to comment on the facilities or lack of them in each standard reviewed. In Part I a comparison of pitting resistance ratings is made, and in the subsequent issue, Part II will deal with bending stress ratings and comparisons of designs.
It is with great anticipation that we move closer to AGMA's Fall Technical Conference and Gear Expo '87, which is being held on Oct. 4-6 in Cincinnati, OH. This bold undertaking by both AGMA and the exhibitors in the Expo's 160 booths is an attempt to make a major change in the industry's approach to the exposition of gear manufacturing equipment. By combining the Expo with the Fall Technical Conference, those involved in gear manufacturing will have the opportunity to review the latest equipment, trends, and most innovative ideas, while keeping up with the newest technology in the industry.
What's not to like about a more focused, user-friendly Gear Expo? Booth Previews.
This issue of Gear Technology, The Journal of Gear Manufacturing, marks the end of our second year of publication. As we approach our third year, it is time to review our statement of purpose. Gear Technology's primary goal was and is to be a reference source and a forum for the American Gear industry, and to advance gear technology throughout the world.
