Gears have powered the world for millennia, from clock machines to car engines. But miniaturizing them to microscopic ...

Different gears like spur, bevel, worm and wormwheel, rack and pinion, meshed gears, and threaded bars serve various purposes. When selecting a gear system, consider speed, direction, force, space, ...

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.

Gears provide two main functions in motion-control systems. In power systems, they match the relatively low-speed, high-torque requirement of the load to the high-speed, low-torque, high-efficiency ...

Depending on how they are manufactured, rack-and-pinion drives can deliver very precise motion, rivaling or exceeding that of ballscrews and even linear motors. Rack and pinions are the other ...

Two new versions of Rack Gears feature 1045 carbon-steel construction and induction-hardened teeth for precise operation, high strength, abrasion resistance, and long service life Two new versions of ...

ABSTRACT MCE-5 DEVELOPMENT has been developing its variable compression ratio engine (VCRi) for over a decade aiming at reducing fuel consumption and pollutant emissions. In order to transmit power ...

If you've ever driven an older vehicle without power steering or a contemporary car with a power steering malfunction, you probably understand just how important these systems are. They drastically ...
