3D Printed Two Stage Planetary Gearbox!

Links to printer and materials used below! - This 3D printed two stage planetary gearbox has a reduction of 64:1. This is a test print in PLA-CF, the final print will be in tougher materials such as PA12 and PC. This was printed on my Bambu Lab X1 Carbon printer! My aim is to get 125 Nm of torque out of the final design!

If you like me wondering about the motor, its Eaglepower LA8318 KV100 Brushless Motor High Power Large Load

[@mxtnr]

where 83 is diameter, 18 is height, 100 is rpm per volt w/o load. bigger diameter - bigger torque, bigger kv - lower torque. kv100 is small enough, diameter is big enough. However is newbie in such topic, so corrections are welcome

[@Joncarlyle01]

Thank you

[@mikegrok]

@@mxtnr there is also the ratio of magnets to coils. The number of magnets must be even. The number of coils must be divisible by three. The closer ratio between the coils to magnets leads to significantly more torque. The rotor you chose is often 12:16, Ie they do a 3:4 ratio and use it 4 times around the circle, which gives it 4 times the torque. A motor with much more torque but a similar build is a 12:14 motor. Look at some of the gimbal motors for examples, someone had I think a 21:22 motor that was 200 times the torque for the same diameter than a 12:16, but hell to machine, and no available off the shelf parts.

@@davemccage7918 depends on the application loading.

[@PartikleVT]

But when made properly out of metal and with proper lubrication will never break. (these are used in the Toyota synergy drive system since the first prius and its never failed). Sometimes its the materials that matter more than the design, sometimes its the other way

[@PartikleVT]

I still think if the application is to use the motor as a generator, then this would still be sturdy enough for hand cranking

[@AlexJoneses]

@@PartikleVT maybe, maybe not, i have no doubt they can hold up to some integer of torque but its definitely pretty low and also plastic gears like this wear pretty fast, espeicially when not made out of the correct plastic, in the correct manufacturing process, and with no lube

Thanks. Info in the description

[@chloeleedow7250]

Quality of those plastic parts looks amazing, they actually look like they'd stand up to crazy high temps if it was needed too.

[@TDPEquinox]

It's PLA-CF so it wouldn't, and wouldn't hold up to any torque either. Should have used nylon. But then the bambu printer wouldn't have been able to do it as well, and that doesn't make a good looking video so PLA-CF it is. Very easy to get good looking prints with PLA, try it with nylon..

[@MattDenton]

@TDPEquinox yes I know. This is a test fit for sizing and assembly. I’ve done test gears in a range of materials including nylon and will test them all to destruction

[@Berkana]

Could you try the same amount of gear reduction in one stage using a compound planetary arrangement? What I mean is that the large planet gears have coaxial small planet gears in one piece with them, and these small planet gears are the part that run in a ring gear. The large radius planets in contact with the sun gear do not touch the ring gear directly with the large radius part. Using a compound planetary gear I described you could theoretically get the kind of gear reduction normally achieved using multiple stages.

Cool design. The initial sun gear and connection to the motor could be a weak spot. Not sure on your print specs, I would be print 4-6 walls and then have a bolt in the center running the full length of the part to distribute the torque through the gear into the base.

@@GeneralKenobi69420 you have no idea what can or can't be 3D printed, and how much torque it can withstand, do you? I've been printing similar parts in FDM, SLA, PBF, SLS for years. But my cheapest print probably costs my clients more than the most expensive eD printer you've ever used.

[@CD-lx6sc]

I remember studying planetary gear sets in trade school, was amazingly complicated but Important to remember what you're looking at here is one very small part of driveline output (if that's what this is for). You need much more components on the control side, planetary gears are only useful if the gear components are individually controllable. Please show more this was very cool.
