A team of New York University scientists has created a gear mechanism that relies on fluids to generate rotation. The ...

Scientists at New York University and NYU Shanghai have developed a new kind of gear that works without teeth or direct ...

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 ...

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

A new study reimagines the 3,000-year-old technology using fluids, avoiding the most annoying limitations of teeth-driven ...

The ATS685LSH is an optimized Hall-effect sensing integrated circuit and rare-earth pellet combination that provides a user-friendly solution for true zero-speed digital gear-tooth sensing in two-wire ...

I am pretty certain lots of folk know, but this ex-electronic engineer didn’t – apart from that they must be to reduce friction in some way. Now I know a little more, though this YouTube video by ...

A new transmission device that uses magnetic levitation to almost completely eliminate friction and wear has been developed as part of the MAGDRIVE research project, a collaboration of seven European ...

Even before the Industrial Revolution, gears of one kind or another have been put to work both for and against us. From ancient water wheels and windmills that ground grain and pounded flax, to the ...
