If u going to build this, then please send me a picture of the INSTAGRAM, I really love to see how people build my designs.
This gearbox has practical use in the real world for sure, and probably even in RC vehicles. Probably u see this gearbox in this channel more.

Nice gearbox! Needs an output stage with output bearings and a overload clutch. (maybe some mounting holes too?) The output bearings are to support overhanging loads, and the overload clutch will make the gear-box bomb proof by slipping before anything breaks. I've made overload clutches both with spring loaded friction clutches and detent mechanisms.

When you print with PETG, be sure to increase the infill. Using different infill patterns will also yield better results too.

@3DRC-707 3 жыл бұрын

Yes absolutely.

@Iron_Lion_Of_Zion 3 жыл бұрын

Also, if u use matrix combining, pre infill stage, u will see 45-50% increase in strength, with approx 15.5 & 17.78% less material used, which on bigger prints all adds up.

@msworkshop522 2 жыл бұрын

Yes, until 40 % there are benefits. Also maximizing the wall lines will give its maximum strength, example with most common settings for every 1 cm2 of item use a setting about 12 wall lines. Also run the hot-end hotter than usual to achieve better bonding. Good video I enjoyed it.

An awesome video like always. Printing the sun gear perpendicular to the force direction will greatly increase strength. What I mean is print the sun gear in two parts (length-wise, perpendicular to the gear teeth). The plastic is failing due to the torsional force being in the same direction as the print layers. The parts will be a lot stronger.

I can't wait to see this channel once metal 3d printing becomes affordable to you. All of a sudden, what previously would be considered toys would become real alternatives to commercial parts and assemblies. Make sure to save every design. With even minimal automation, I can see how this might turn into a business - selling assemblies that now are durable enough to use for hobbyists and eventually professionals.

Ok bro, you got me. Liked and subscribed with notifications plus a little engagement here for the algorithm. You're very talented. Not only in mechanical engineering, but you're a master of 3D printing! People who haven't 3D printed before just think you click print and out comes a perfect object. They don't understand bed leveling, offsets, rafts, infill, elephant foot, supports, overhang, bed and nozzle temperature, nozzle cooling, extrusion size and feed rates, etc, etc...there is so much that goes into getting a perfect print and you make that part look easy.

i think that a nice idea would be to print with increasing stage thickness, so the gears are thicker when more torque is needed and thinner when they spin faster to reduce drag and gearbox size, if i will prints these i think i will try, being in need of pretty high reductions

@mozkitolife5437 3 жыл бұрын

Fascinating, your prints were almost hollow in the first round and yet still managed to pull up 20kg. If they manage to make the plastic bond as strong as injection molding, this would be a great way of saving lots of materials.

You should print the gears as separate pieces then the shaft (click together after print). If you do this you can print the shaft with the layers along the length and it will be much stronger to shear forces.

To push in the bearings, if you need to "hammer", use a piece of pipe, or a socket of the same diameter as the outer bearing race...you can use something like "water pump pliers", in place of a vise, again with a little piece of pipe, or a spare bearing, to push the bearing into the gear.

you should try to make a automatic or manual planetary gear box. planetairy gearboxes are often used in things like cars and drills due to the simplicity or making it shift gear ratio. doing that would allow you to always use the exact same gearbox, you only need to set it to a gear, or you can set it while running electronically which allows for a better speed to torc/acceleration ratio.

If this were made with herringbone, I think to load them in you would need the case to open from side instead of from the front, but all the gears would stay better in there place. There is something about planetary gears that always kicks me into nerd gear.

I'm wondering what kind of speed you can get if you run this gear box with the input running the other way using the 8 motor gearbox as the input, would be interesting to see the kind of speed and force it can generate with a fan or pump connected as the output of those 2 projects tied into each other, plus material testing for extremes of speed rather than torque.

Nice gearbox but why didn't you use a design where you could access the bearings inner ring from both sides? In this way you could have tightened up the mounting screws in the planet gear carrier more decent and without paying too much attention to the mounting torque. This would also make your design more robust and lead to a more precise movement of the planet gears...

I think about the same. My gears also melted because of friction on one side.

@peterciurea7771 3 жыл бұрын

Try making some strain wave(harmonic) drives as well as some cycloidal - see if they are more forgiving of the material. There is a type of strain wave drive in which you can use a ready made rubber timing belt, the type usually used with steppers, as the flexible gear.

This is really cool, the concept of stackable modules.. 👍 I'm wondering if you can measure how much the power/torque increases with each module added, and if the increments are linear.. 👀 I think 3d printed gears might actually be useful even for heavier applications, if the end parts that carry the load are made of metal... Great job! Also, have you tried to print with what they call "black aluminium"? It is nylon/carbon mix... not sure of the brand name (s). Good luck with your projects!

The first test (10kg, 35cm) was way, way harder on the gears and motor than any other test that followed in the video. That first one was 3.5 kg*m, while that last, 40 kg test was only some 1.2 kg*m (assuming a 3cm radius winding - it was probably less than that).
