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.

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 ...

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

As one of the oldest components of human engineering, gears have driven civilization for ...

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 ...

Some spare time recently got used-up designing a pair of involute gears – which, it transpires, is easy in principle, once certain almost-impossible-to-obtain facts have been gathered. There are ...

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 ...

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.
