Another one of those graduate student requests turned up in my e-mail inbox this week. This one referenced one of my AGMA Fall Technical Meeting pa...

In several applications like hoisting equipment and cranes, open gears are used to transmit power at rather low speeds (tangential velocity < 1m/s) with lubrication by grease. In consequence those applications have particularities in terms of lubricating conditions and friction involved, pairing of material between pinion and gear wheel, lubricant supply, loading cycles and behavior of materials with significant contact pressure due to lower number of cycles.

Back when getting ISO 9000 certified was “the thing,” companies were expected to have a mission statement. I retroactively confess to not being a “...

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?

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

In my last post I insisted that good design wins in the marketplace. As a student of automotive history, I am compelled to admit that some very gre...

One of the things I mention when teaching about gears is the long history of great minds who have contributed to our field. Early readers of Ge...

One of the few things I miss about my old commute is all the great content I heard on public radio. Ten hours a week of news, in depth features, an...

Ranting about needless software upgrades got me thinking about why we love “new” things. Aren’t there some things we should leave well enough alone...

More than 100 years ago, gear manufacturers were facing a significant challenge from industry. The incredible advances in industrialization and transportation that occurred at the turn of the 20th century resulted in incredible growth for gear makers, but there were significant technical issues. "The lack of process and product standardization was a continuing problem in all U.S. industry. The lack of industry-wide gear standards meant there were no standard gear tooth sizes, ratings, quality definition or consistent manufacturing methods" (Celebrating 100 Years of Gearing, pg. 22).
