Another finding demonstrated by Dr. Strehl’s manufacturing simulation was the reduced investment costs for a new gear factory when going the PM route. In...
Cycloidal teeth must not only be accurately spaced and shaped; their wheel centers must...
In 1900, Wilfred Lewis discussed gear tooth forms at an ASME meeting: "About 30 years ago, when I first began to study the subject,...
Powder Metal Gears, Part VII
So far, five powder metal gear related topics have been covered: effects of porosity, noise and NVH, micro design and robustness, macro design and...
The spiral tooth form, as with the helical gear, provides a smoother and higher...
An analogy can be drawn between a spur and helical gear and the straight and spiral bevel gear. The pitch surfaces and the conjugate...
Machining – more specifically, the tools that make removing metal possible
Decades ago there was only one option: High-speed tool steels such as molybdenum types M2, M4, M50, and the tungsten series T15 for example....

Tell our readers a little bit about the workholding products Fairlane provides.
We manufacture serrated grippers and other workholding components—the contact points that hold onto...
Powder Metal Gears, Part VI
The heat treatment issue discussed in previous columns remains for the rollforming as well; low-pressure carburization helps, due to a better process when introducing...
There are four standardized AGMA systems of bevel gear tooth proportions: 20° straight bevel,...
In this month’s edition of Tooth Tips, let’s take a look at bevel gears at angles other than 90º.
When the sine of the angle...
