Magnetic Wobbling Gearbox 3D Printed

[@Skyentific]

Amazing! Good job!

[@PaulGouldRobotics]

Thanks, I might try your Orbital drive next.

[@MrIronstork]

You need "Pocket NC V2" . me too. This is the minimum.

[@PaulGouldRobotics]

I would like a Pocket NC, but my main aim to to design things that anyone with a cheap 3D printer and some simple tools can make.

[@quinnfoster4671]

@@PaulGouldRobotics admirable!

[@PowerScissor]

What's the scenario where this would be advantageous over a standard 11:1 gearbox? Also, I hear backlash all the time but am not 100% sure what the term means. Is it the slop in the input between the output being driven forward vs driven in reverse?

[@PaulGouldRobotics]

Advantages- no teeth contact, no friction, overload protection & high efficiency. More details in the research papers in the description. You are correct, backlash it is the slop between the input and output shafts.

[@chenhan91]

how much torque can this gearbox hold? looks like a stepper motor

[@PaulGouldRobotics]

It is somewhere between 5Nm and 10Nm.

[@kaden56]

I have never seen one of these! Very cool. Good work as usual.

[@PaulGouldRobotics]

Thanks, I've got a few more strange gearbox designs to share in the future

Great job Paul!

I love mechanisms, Nice job

[@jameskirk4498]

Cool design what if you put it in a robot arm

[@PaulGouldRobotics]

I would need to be improved the design a fair bit. It is large/heavy for the amount of torque it transfers. It is not balanced. It is also quite expensive $50 for magnets and $20 of bearings. It was just a proof of concept.

[@PaulGouldRobotics]

@@jameskirk4498 Triple Disk, single stage cycloidal gearboxes are my favorite at the moment. How small are you looking at? What type of robot are you making?

[@PaulGouldRobotics]

@@jameskirk4498 For that size, RC/smart servos are your best choice

[@ddegn]

I've done enough KZbin research to know that device produces anti-gravity and/or free energy. Seriously, you did a great job showing the mechanism but I think I'll need to watch the video a few more times to grok it.

[@xxportalxx.]

If you replaced the outer stator with that of a stepper motor I wonder if you could very the gear ratio by changing the step size, ofc I do not know off the too of my head if that's possible without having the poles changing as they do in the motor

[@PaulGouldRobotics]

That is what Magomatics does.

[@xxportalxx.]

@@PaulGouldRobotics oh interesting, I'll have to look into that, thanks!

[@brianboni4876]

Thanks for sharing.

[@igorandrusyk2307]

Is it possible make higher gear ratio for this construction??

[@PaulGouldRobotics]

Yes, smaller magnets and less spacing could get about twice the reduction in the same diameter.

[@igorandrusyk2307]

@@PaulGouldRobotics thanks

[@FilterYT]

Cool Paul, appreciate learning something new.

[@PaulGouldRobotics]

Thanks, there are many different types of magnetic gearbox. I've made a few now.

[@gigagrain]

Super cool

[@PaulGouldRobotics]

Thanks

[@DerSolinski]

Interesting design, what where your intentions back when you made it?

[@PaulGouldRobotics]

I was trying to find the perfect gearbox for a quadruped robot. I like that is springy and skips when overloaded, so jumping and landing are damage free (SEA). I find that the best way to learn about something, is to make it.

[@DerSolinski]

@@PaulGouldRobotics There is an idea ripening in my head for a low cost elastic torque actuator with adjustable springiness. It is still a concept and has many flaws, but I guess just building it would be way faster then brooding over it 🤣 I'll make a video once it is build maybe you'll have use for it. But it will take some time, I moved and are still missing some vital furniture... like a kitchen 😅 or a suitable workbench...

[@ddegn]

@@DerSolinski I went to your channel hoping to see your device. I was disappointed to find ZERO videos. I hope you start sharing your projects.

[@DerSolinski]

@@ddegn I haven't made any videos yet... Honestly life keeps throwing moon sized curveballs at me. Every-time I want to start a serious project which requires some legal tender I'm forced to use it elsewhere. And right now I'm searching for a new job while corona is ravaging the planet, good luck with that 😑

[@ddegn]

@@DerSolinski Agreed, it's a bad time to be out of a job. FWIW, putting projects online can be very useful for gaining employment. I don't post a lot of my projects but projects I've posted has helped me stay employed. I've had paid gigs several times from people seeing my projects I post online. Good luck.
