Motorized goniometric stage 

What

Cradle tilt

I made it without calculation. Just "try and adjust". The worm: 1 start, module: 2, outer diameter: 24 mm The wheels: 285 and 400 teeth.

The point is to invent your own. What you _need_ is some understanding of basic mechanics - Levers, gears, cams, etc; Multiplication and division of moments and angles and distances via first-order mechanical principles. You could look at some videos describing principles of operation of mechanical computers perhaps, especially those that used to be found as targeting computers on WWII battleships and the like as I am aware of a few videos that exist specifically describing that topic in detail.

My videos are built up based on following sources: - Textbooks - The Internet - Requests from RU-vid viewers - What I see in practice or I imagine. My favorite books: 1. С. Н. Кожевников и другие, Механизмы, Москва, 1965, 1060 стр. 2. I. Artobolevski, Mechanisms in modern technic, Moscow 1977, 7 vol. 3. Sclater & Chironis, Mechanisms and Mechanical Devices Sourcebook, 2001, 485 p. 4. Henry T. Brown, 507 Mechanical Movements, New York 1908,122 p. 5. А. Ф. Крайнев, Словарь Справочник по Механизмам, Москва, 1987, 561 стр. 6. Mechanical Fixtures Tooling

almost 5 years ago I asked this same thing to Thang...and he delivered twice. Thank you

@@UnitSe7en Makes sense, I'll look up those mechanical computers for sure! The website "507 mechanical movements" also helps. In addition, I came across a mechanical fourier transform machine from the 1920s and it was fantastic. The Engineer Guy has a video on it here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-NAsM30MAHLg.html

@@thang010146 Thank you so much for sharing!

I don't quite understand your request. Maybe a sketch will help me. My email: thang010146@gmail.com

Link to download the STEP files has been added to the video description recently.

@@thang010146 Thank you very much! Btw, I have one question to ask regarding the design of the goniometric, do the worm gear must be placed on the centre of the stage? I mean, can I put it like slightly left or right of the stage? does the stage supported fully by the gear worm beneath it?

Centering is the best. But slightly left or right placing is acceptable. The gear worm does not bear the stage weight. The circular runways do that. The gear worm only applies torque to the stage.

@@thang010146 Thank you so much for the reply!

All videos in this channel are made in Autodesk Inventor, Dynamic Simulation.

It can be, for example, a rack-pinion transmission. However, it does not have a self-locking feature, so a position locking device is required for the output.
