“We invented new types of gears that engage by spinning up fluid rather than interlocking teeth—and we discovered new ...

From the chariot wheels crossing the Gobi Desert in 3,000 BCE to the intricate bronze clockwork of the Antikythera mechanism ...

Gear tooth geometry is determined primarily by pitch, depth, and pressure angle. Pitch: Standard pitches are usually whole numbers when measured as diametral pitch P, the ratio of the number of teeth ...

Invention of the gear-hobbing process about 150 years ago revolutionized not only gear fabrication, but also gear design. Basically, a hob or shaper cutter traverses the gear blank to generate teeth.

The design and analysis of spiral bevel and hypoid gears have evolved into a critical area of research, given their vital role in high-performance industrial applications. Recent advances integrate ...

A single-chip solution that integrates three highly sensitive Hall elements—a samarium cobalt magnet, a pole piece and a Hall-effect IC—the ATS65OLSH is intended for digital gear-tooth sensing and ...

Simulation tools are now available to simulate complex gear measurements after heat-treatment simulation. This is the focus of the feature article that has just been published in Thermal Processing, ...

The ATS617 gear-tooth sensor IC is a peak-detecting device that uses automatic gain control and an integrated capacitor to provide extremely accurate gear edge detection down to low operating speeds.

The teeth of teeth of involute gears hobs and teeth for involute spline shaft hobs have a trapezoidal profile. In the U.S. a huge volume of good quality hobs are produced, and offers potential for ...
