Honored and Impressed

At the AGMA annual meeting last month, the association presented me with its Distinguished Service Award.

Girth Gears - More than Just Metal and Teeth

Large, multi-segmented girth gears do not behave like the relatively compact, rigid, monolithic structures we typically envision when discussing gear manufacturing. Girth gears are very large, non-rigid structures that require special care during the machining of individual mating segments as well as the assembled gear blank itself.

Inclusion-Based Bending Strength Calculation of Gears

Reduced component weight and ever-increasing power density require a gear design on the border area of material capacity. In order to exploit the potential offered by modern construction materials, calculation methods for component strength must rely on a deeper understanding of fracture and material mechanics in contrast to empirical-analytical approaches.

Performance and Machining of Advanced Engineering Steels in Power Transmission Applications - Continued Developments

It is becoming increasingly apparent that material properties can and will play a greater role than before in addressing the challenges most transmission manufacturers are facing today. Making use of materials' intrinsic fatigue properties provides a new design tool to support the market changes taking place.

Upgrading Your Toolbox

Manufacturers focus on tool design, materials, coating, machine tool options and cutting parameters.

Gear Design Deconstructed

How difficult is it to design a gear? It depends upon whom you ask.

Transmission Throwdown

Which transmission system will come out on top is a hot topic in the automotive community. With multiple transmission-centric conferences on the horizon, there will be plenty of debate, but how much will the answer actually affect gear manufacturers, and when?

Can Lean Manufacturing Kill Your Job Shop

The presidents of two manufacturing companies were having a drink in the lobby before the start of their trade association's annual meeting...

Gear Teeth as Bearing Surfaces

A reader wonders about gears where the tops of the teeth are the bearing surface, as used in spur gear differentials. Do they require any special construction or processing?

The Guy Who Put the Gearbox Up Front

As the Indianapolis 500 begins its second hundred years, it is a good opportunity to recall the guy who put the gearbox "up front."
