Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.

The past four decades of designs have added up for Seirus Innovation. Beyond creating an impressive collection of high-quality, purpose-built winter gear, the California-based accessories brand has ...

Gears are everywhere - from clocks and cars to robots and wind turbines. For more than 30 years, researchers have been trying to create even smaller gears in order to construct micro-engines. But ...

There are many more driven gears available than drive gears. In traditional GM transmissions, typically available TH350 (also fits most manual boxes) driven gear selection ranges from 18 to 25 teeth.

Few vehicle modifications have as major an impact as changing gear ratios, and it's because your car's gear ratio directly translates to how it delivers power. Think about it: The gear ratio, or how ...

There are a number of ways to transfer an engine or motor's power into drive, and these are generally split into two camps -- automatic and manual transmissions. While gear-based transmissions have ...

'It seems pretty simple, one shaft turning another, and with gears, chains, or belts, there are a variety of devices for getting the job done. We're talking about the camshaft, and there are a variety ...
