Material Grade in Gears

Material Grade in Gears

The reason not all gears can be made from the same material grade has to do with hardenability. We have long unde...

Remembering Panhard and Levassor, the company that invented the first manual transmission.

The complete industry news section from the June 2018 issue of Gear Technology.

A reader asks: We are currently revising our gear standards and tolerances, and a few problems with the new standard AGMA 2002-C16 have arisen. Firstly, the way to calculate the tooth thickness tolerance seems to need a "manufacturing profile shift coefficient" that isn't specified in the standard; neither is another standard referred to for this coefficient. This tolerance on tooth thickness is needed later to calculate the span width as well as the pin diameter. Furthermore, there seems to be no tolerancing on the major and minor diameters of a gear.

With increasingly smaller returns from improving the speed of the actual gear grinding process, improving your setup time has become a primary way to keep improving efficiency. Here's the latest on how you can do that today.

If my last posting prompted you to look at a copy of a material cert, you probably noticed that the cert has much more information on it than just ...

So, what exactly do we mean when we say “use good material” for your gears? Once again, the answer is “it depends.” Even the “best” steel may be wr...
