The last stronghold for herringbones was — and remains — the venerable oil field pumpjack gearbox. Although known by a variety of other names, noth...

A road map is presented listing critical considerations and optimal use of materials and methods in the construction of large gears.

Bradley University and Winzeler Gear collaborate on the design and development of an urban light vehicle.

If someone were to tell you that he had a gear material that was stronger per pound than aluminum, as wear-resistant as steel, easier to machine than free-machining steel and capable of producing gears domestically for 20% less than those now cut from foreign made forgings, would you consider that material to be "high tech"? Probably. Well, throw out all the pre-conceived notions that you may have had about "high tech" materials. The high-performance material they didn't teach you about in school is austempered ductile iron (ADI).

This paper addresses Austempered Ductile Iron (ADI) as an emerging Itechnology and defines its challenge by describing the state-of-the-art of incumbent materials. The writing is more philosophical in nature than technical and is presented to establish a perspective.
