Gear Manufacturer Benefits from CAM Initiatives and Advanced Manufacturing Technology
Multiple CAM initiatives at Snyder Industries are improving safety, quality and productivity for parts ranging from 50 to 5,000 lbs.

Getting the Right Tools
So there is little chance that they need the same software to assist with their work. Gone are the days when companies wrote their own code and process engineers thumbed the same tattered reference book.

Who Is Afraid of Innovation
There are varying opinions as to what constitutes innovation, but in our industry and in the engineering world as a whole, we typically think of innovation as being the use of technologies different from those we use at the moment to do things better, faster and cheaper.

Less Energy Consumption with High-Efficiency Bevel Gears and their Usage in the U.S.
The efficiency of a gearbox is the output energy divided by the input energy. It depends on a variety of factors. If the complete gearbox assembly in its operating environment is observed, then the following efficiency influencing factors have to be considered

Micropitting of Large Gearboxes: Influence of Geometry and Operating Conditions
The focus of the following presentation is two-fold: 1) on tests of new geometric variants; and 2) on to-date, non-investigated operating (environmental) conditions. By variation of non-investigated eometric parameters and operation conditions the understanding of micropitting formation is improved. Thereby it is essential to ensure existent calculation methods and match them to results of the comparison between large gearbox tests and standard gearbox test runs to allow a safe forecast of wear due to micropitting in the future.

Simulation of Deviations in Hobbing and Generation Grinding
The hobbing and generation grinding production processes are complex due to tool geometry and kinematics. Expert knowledge and extensive testing are required for a clear attribution of cause to work piece deviations. A newly developed software tool now makes it possible to simulate the cutting procedure of the tool and superimpose systematic deviations on it. The performance of the simulation software is illustrated here with practical examples. The new simulation tool allows the user to accurately predict the effect of errors. With this knowledge, the user can design and operate optimal, robust gearing processes.

Cracking the WIP (Publishers Page)
Over the past few months I've talked with several different gear manufacturers who are in the process of upgrading their gear making equipment with modern CNC machine tools. Each of these manufacturers has come to the realization that in order to stay competitive, he needs to streamline operations and become more efficient...

Leading by Example - Remember When (Voices)
In January of this year we at Gear Technology got hip to the fact-in un-hip, belated fashion - that we needed a Blog Site and someone to do the blogging. Lucky for us, we already had that someone right here - in plain sight. That someone was Charles D. Schultz, P.E.

Lubrication Lexicon (Ask the Expert)
I must confess I sometimes find myself a bit dazed when discussing lubrication issues with either staff or vendors. The terminology seems to be all over the lot, with some terms having double meanings. Can you help cut through the confusion?

LES GEARS LYONNAISE (Events)
Soon upon setting down in this beautiful, former (43 B.C.) Roman Colony that is now the City of Lyon, I was careening to my hotel, Mach I-plastered to the back seat of a sleek, shinyblack Mercedes taxi, when I realized I was staring at - zut alors? - cornfields!

From Bauhaus to Gearbox (Addendum)
Arguably the city of Chicago’s most compelling, dynamic period — early 1930s -1960 — is dramatically evoked in Thomas Dyja’s 2013 book, THE THIRD COAST — When Chicago Built the American Dream.
