Gear Design Deconstructed

May 1, 2017

Jack McGuinn

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

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?

Girth Gears - More than Just Metal and Teeth

May 1, 2017

Steve Lovell

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

May 1, 2017

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

May 1, 2017

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.

Gear Teeth as Bearing Surfaces

May 1, 2017

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?
