Motors and gear trains with micrometer dimensions and powered by light are fabricated using semiconductor lithography and ...

You can buy gears off the shelf, of course, and get accurately machined parts exactly to your chosen specification. However, there’s something rugged and individualist about producing your own ...

Noiseassociated with gear trains has been a common problem for gear designers for along time. With the demands for smaller gearboxes transmitting more power athigher rpm, coupled with incumbent ...

Noisy gear trains have been common problem for design engineers for a long time. rowning can reduce vibration and limit noise without increasing costs. Noisy gear trains have been common problem for ...

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 ...

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.

This article was updated Feb. 28, 2023. It was originally published March 1, 2000. Planetary gears can supply high levels of torque and high-speed reduction. They are also relatively compact compared ...

Automatic transmission systems (ATSs) are critical components in modern vehicles, integrating complex gear mechanisms to optimise performance, efficiency and durability. These systems utilise an array ...
