Engineers reinvent the 5,000-year-old gear using fluids instead of solid teeth.

Researchers are developing a new transmission mechanism with no touching parts, based on magnetic forces which prevent friction and wear and make lubrication unnecessary. It can be applied in space ...

The study, published January 13 in Physical Review Letters, replaces the metal or plastic cogs of conventional gears with controlled flows of liquid. In their experiments, ...

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 ...

Generally speaking, the gear mechanism of automobiles and bicycles is usually to increase or decrease the rotation speed in one direction, but by using a special mechanism it is possible not only to ...

Previously believed to be only human-made, a natural example of a functioning gear mechanism has been discovered in a common insect -- showing that evolution developed interlocking cogs long before we ...

A team of scientists at the University College London has shed new light on the Antikythera Mechanism – the world's first computer and one of the ancient world's greatest technological mysteries.
