Articles About green


1 Green Heat Treating - No Sweat (November/December 2009)

Bob McCulley of Comprehensive Heat Treat Specialists describes how even the most energy intensive industrial processes can be made "green."

2 The Business of Going Green (August 2008)

Heat treatment industry reinforces environmental/energy conservation.

3 Green Gravy (January/February 2009)

Step right up! Get your U.S. government gravy here! We’re the U.S. Treasury Department’s Troubled Asset Relief Program, and we’re printing money like we’re—well—the U.S. reasury. If you’ve got trouble, then get your assets in line!

4 Greener Gears (July/August 2004)

Companies around the world are learning to embrace the environment, and the gear industry is no exception. This special section takes a look at how some gear manufacturers are doing their part to conserve resources, preserve and protect the environment, and give back to the land. What we’ve found is that adopting environmental measures is far more than just good corporate citizenship. For many gear industry companies, good environmental practices also turn out to be good for the bottom line.

5 The Changing Industrial Landscape (March/April 2009)

Companies weigh in on green technology and sustainable efforts.

6 Hotter, Faster, Harder Cutting (July/August 1995)

What Is Whisker-Reinforced Ceramic? Whisker-reinforced ceramic as applied to cutting tool inserts comprises a matrix of aluminum oxide into which approximately 50% by volume of high-purity silicon carbide "whiskers" are randomly dispersed. The "whiskers" are, in fact, single crystals having dimensions of approximately 0.6 microns in diameter x 10-80 microns in length. These "whiskers" have a tensile strength on the order of 1,000,000 psi (690 MPa). The composite material that is the best known and most widely applied using this technology is designated WG-300 and manufactured by the Greenleaf Corporation of Saegertown, PA.

7 Greenhouse of the Gear Industry (May 2011)

Publisher Michael Goldstein talks about how one gear company is encouraging young people in manufacturing. What are you doing?

8 Deburring & Finishing Gears with Power Brushes (March/April 1989)

Why Brushes? In this age of hi-tech, robots, automatic machines, machining cells, etc., is there a niche somewhere for power brushes? Let me answer by asking another question. What tool does the gear manufacturer have in his arsenal that allows him to deburr green gears, hardened gears, hobbed gears, ground gears and shaved gears? What tool allows him to deburr powder metal gears - green and sintered - brass gears, bronze gears, stainless gears made of exotic materials such as inconel, waspaloy, or hastaloy, and fiber and plastic gears? How about spur gears, helical gears, sprockets, both internal and external splines, clutch teeth and pump gears?

9 Light Weight Assembled Gears - A Green Design Solution (May 2013)

It is widely recognized that the reduction of CO2 requires consistent light-weight design of the entire vehicle. Likewise, the trend towards electric cars requires light-weight design to compensate for the additional weight of battery systems. The need for weight reduction is also present regarding vehicle transmissions. Besides the design of the gearbox housing, rotating masses such as gear wheels and shafts have a significant impact on fuel consumption. The current technology shows little potential of gear weight reduction due to the trade-off between mass optimization and the manufacturing process. Gears are usually forged followed or not by teeth cutting operation.

10 Gearbox Speed Reducer Helps Fan Technology for "Greener" Jet Fuel Efficiency (August 2008)

Today’s ever-evolving global economic engine is, in many ways, a wonderful phenomenon; you know—a rising-tide-lifting-all-boats, trickle-down-theory-of-economics dynamic at work.

11 Gear Greenbacks (September/October 2004)

Imagine the $10 bill with the face of Edwin R. Fellows on it and on the back, a picture of his invention: the gear shaping machine. Or the $5 bill with George B. Grant and a picture of the first hobbing machine, which he built.

12 Magnetic Gearing Attracting More Followers (August 2013)

"Going green" and energy efficiency are goals that all industries -- especially in Europe and the United States -- are working on, in such sectors as electric motors, lubrication, gears and on and on. Drumroll here please for magnetic gearing

13 Hard Finishing and Fine Finishing Part 1 (September/October 1989)

Profitable hard machining of tooth flanks in mass production has now become possible thanks to a number of newly developed production methods. As used so far, the advantages of hard machining over green shaving or rolling are the elaborately modified tooth flanks are produced with a scatter of close manufacturing tolerances. Apart from an increase of load capacity, the chief aim is to solve the complex problem of reducing the noise generation by load-conditioned kinematic modifications of the tooth mesh. In Part II, we shall deal with operating sequences and machining results and with gear noise problems.

14 Gear Finishing by Shaving, Rolling and Honing, Part I (March/April 1992)

There are several methods available for improving the quality of spur and helical gears following the standard roughing operations of hobbing or shaping. Rotary gear shaving and roll-finishing are done in the green or soft state prior to heat treating.

15 No Gear Job Too Small (March/April 2007)

The greenlighting of new product designs specifying micro-sized, plastic gear sets is often dependent upon existing technology and a company’s capabilities to manufacture those gears, and to do so cost-effectively

16 An Innovative Way of Designing Gear Hobbing Processes (May 2012)

In today’s manufacturing environment, shorter and more efficient product development has become the norm. It is therefore important to consider every detail of the development process, with a particular emphasis on design. For green machining of gears, the most productive and important process is hobbing. In order to analyze process design for this paper, a manufacturing simulation was developed capable of calculating chip geometries and process forces based on different models. As an important tool for manufacturing technology engineers, an economic feasibility analysis is implemented as well. The aim of this paper is to show how an efficient process design—as well as an efficient process—can be designed.

17 Gone Fishin' - Back After Gear Expo (September/October 2001)

It's summertime in the gear industry. Out my window, I see blue skies, green grass and trees swaying in the wind. In the background, I hear crickets chirping.

18 It's No American Dream: Pratt & Whitney GTF Engine Now a Reality... (November/December 2011)

In the August 2008 issue of Gear Technology, we ran a story (“Gearbox Speed Reducer Helps Fan Technology for ‘Greener” Jet Fuel Efficiency’) on the then ongoing, extremely challenging and protracted development of Pratt & Whitney’s geared turbofan (GTF) jet engine.
