Mechanical Gears facts

While investigating facts about Mechanical Gears 3d Wooden Puzzle and Mechanical Gears Tattoo, I found out little known, but curios details like:

The small hopping insect Issus Coleoptratus uses toothed gears on its joints to precisely synchronize the kicks of its hind legs as it jumps forward. This insect has the only mechanical gears ever found in nature

how mechanical gears work?

The Larvae of the Planthopper bug is the first living thing discovered to have evolved mechanical gears. They're located in its legs and enable it to jump at an acceleration of 400Gs in 2ms.

What is the mechanical advantage of gears?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what are mechanical gears. Here are 20 of the best facts about Mechanical Gears Drawing and Mechanical Gears Images I managed to collect.

what are gears used for in mechanical devices?

1. There is a bug that evolved to have actual mechanical gears

2. The reason the snooze on a clock is 9 minutes is because in the 1950s, they had to make snooze gears fit onto the existing clock mechanics. Unable to use 10, they chose 9 minutes.

3. The 9 minute alarm clock "Snooze" is a holdover from when clocks had mechanical gears

4. Gear mechanisms were thought to be man made, only to be found naturally occurring on a common insect in its early stage of life

5. The Antikythera mechanism had at least 30 gears, although there could have been more as the ancient Greeks were surely capable.

6. In order to operate the Antikythera mechanism a hand crank was used, which was linked to the largest gear via a crown gear. This gear moved the date pointer to the correct calendar date.

7. Issus, a plant-hopper that has hind-leg joints with curved cog-like strips of opposing 'teeth' that intermesh, rotating like mechanical gears to synchronize the animal's legs when it launches into a jump. The gears in hind-leg bear resemble those found on bicycles and inside cars gear-boxes.

8. There is an insect that has toothed gears resembling mechanical gears on its hind legs, which it uses to jump.

9. Chicken Run for the PlayStation shares the same stealth mechanics as Metal Gear Solid

10. A Geneva Drive is a gear mechanism that translates a continuous rotation into an intermittent rotary motion

Why mechanical seal failure?

You can easily fact check it by examining the linked well-known sources.

In 1780 James Watt did not wish to pay to license the use of James Pickard's mechanical crank patent and instead invented the sun-and-planetary gear assembly to transfer reciprocating steam engine motion into rotary motion.

About Lehmer Sieves: electro-mechanical devices capable of doing large number factorizations and other operations very quickly. Invented in 1926, working models have been constructed using punched tape, bicycle chains, gears, and even 16mm film. - source

The distinct clacking sound old movie projectors make is due to an intermittent gearing system called the Geneva Mechanism. - source

A common garden bug, the leafhopper, has a unique set of natural mechanical gears that it uses for jumping.

Mechanical gears existed biologically and predated man. - source

When is the mechanical engineering board exam?

The first use of differential gear is in a mechanical compass

How to calculate mechanical advantage of gears?

There is a bug called the Issus coeleoptratus which is the only animal with mechanical gears in its body. The gear teeth have a width of 80 micrometers.

Mechanical gears appear in nature and some insects have joints with intermeshing teeth to synchronize their legs during jumps.
