A bunch of years ago, I worked on a navigation system, mainly used in cargo aircraft. It used a ground facing radar that used a Geneva drive to switch wave guides. The very first thing you're taught is to put your ear to the cargo bed and listen for the clack, clack of the drive. If you didn't hear that, the antenna was bad, or the spring drive from the Geneva drive motor to the rotary wave guide had broken, it was nothing more than a spring universal joint. Crew chiefs would always give me a dirty look listening for it,.
Before the servo motors became popular this mechanism was the most common drive in the food industry. On the right side a continuous electric motor and the left side to drive a chain with ice creams, cookies, choclat bars, pizza's, or anything that needs a filling or topping.
Nice animation of basic Geneva mechanism. Those saying that it can lock up or move out of sync would of benefited from a ISO metric view of the assembly. In Top view only it is easy to miss the centre shaft acting as a positive locating pin.
@@lightbatmen Прочитал, мнения не изменил. Это НЕ аналог механизма обтюратора. Аналогичность подразумевает аналогичную функцию. Он скорее аналог грейферного механизма, который применялся в 8мм проекторах. А обтюратор да, использовался при смене кадров. Но выполнял совсем другие функции. Перекрывал световой поток при смене ( и не только) кадра, а вот менял этот кадр мальтийский крест.
It has that in the "crescent moon" feature on the rotating component on the right. The left hand component is either locked in position or actively being driven by the pin in the slot. It's impossible for the mechanism to get out of sync. A typical use for this type of mechanism would be to transport motion picture film through a camera or projector, where the film is alternately held stationary in the gate and advanced rapidly to the next frame.

Looks like a cool engine in the making
Empressed from that angle showed up...

So interesting and useful animation!!

POV: you just watched
3-stage Geneva mechanism to measure the number of rotations
Very nice
Nice gear
Genius
Una variante del mecanismo Cruz de malta
Nice
Это аналог механизма обтюратора - использовался в плёночных кинопроекторах для смены кадров.
Точнее, это "мальтийский механизм".
Мне эта штука часы напомнила
Обтюратор это немного другое, тот перекрывает световой поток, а этот работал в качестве скачкового механизма.

@@korikkk вы ослепли?! Там же напечатано "Точнее, это "мальтийский механизм"." Неуж-то с двух попыток не смогли прочитать?!
What software did you use to create this?
Model by Rhino 3D, Animation by 3ds max + MAXScript.
Try to use MAXScript to complete the calculation.
Nous l' avons toujours nommée "Croix de Malte". Bien ajustée c'est un mécanisme infaillible. Très souvent utilisée aux "Machines Dubuit".

interesting !
Old fashioned cinema cameras everything with word Geneva related with watches or 24 frame per second cameras.
I was thinking the same :-)

Film projector's heart
What is relationship between that side and that angles?
I just use Trigonometric functions to Calculate its movements.
@@Janara1943 so do u found any interesting information?
Bah.... è una semplice meccanismo a Croce di Malta. Esiste dal 1800....
На первый взгляд просто
Well I see this one jamming badly...
Sorry, Just Use 3D to Simulate the Action.
Not quite right.
@@Janara1943 what do you mean?
It needs off-set kill protection or it is a disaster waiting to happen.

The sum of the three angles of any triangle is equal to 180 degrees. And in your video is not, therefore wrong calculations.
It was in the post-processing of the film to Retouch Him. ^_^
There aren't 3 angles shown. Two of the numbers are angle measures, and the third is a side length.
Nice show, awful music!
