Gear Materials: More Inside Heat Treating Trivia
In our last blog on heat treating, lab tests and hardness testing, I mentioned the large number of hardness measuring systems that are in use […]
Gear Materials: You Don’t Know What You Don’t Know
Before we leave our study of materials, I want to share a few thoughts on heat treating, lab tests, and hardness testing. When you start […]
Options for Material Selection
Disclaimer: This is the policy I follow for material selection. Your situation may call for a different decision. You should not adopt this policy without […]
Can We Use This Instead?
Right up there with the dreaded “blank sheet of paper” is the inevitable question of “Can we use this instead?” It came as a real […]
Hardenability 102
Material Grade in Gears Each grade of steel has a distinct “hardenability profile.” Some provide great hardness at shallow depths and then decline rather rapidly […]
Hardenability 101
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 […]
Parsing the Fine Print
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 […]
Read the Label Carefully
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” […]
The Right Stuff
Even the most brilliant gear design will fail if the wrong material is used to make the parts. Our understanding of metallurgy and alloying elements […]
Further Modifications
You might be thinking this conversation would logically move to other tooth modifications. Gear Technology has and will continue to publish many fine, scholarly papers […]
