U also need:
775 DC motor: ali.ski/CJuTrg
2x bearings 608zz (8x22x7mm): ali.ski/WLhiG
M4 threaded insert kit: ali.ski/OPwin
This gearbox has an 8:1 gear ratio, this is designed for 775 DC motor and the application is aimed for RC vehicles. The double shaft makes it possible to connect bought wheels to the output gear at the same time, but of course, if u print and build this by yourself the application is up to you.

@gaussgreen7921 Год назад

to keep using herringbone gears and avoid interference in the middle (where the two helixes meet) you should add a small fillet on the concave side and a large fillet on the convex.

@diminacomusic7070 10 месяцев назад

LMAO! I identify so hard with the part where you mess one insert up and go "oh well i can still try the other side" the proceed to have just as much trouble the second time haha...oooooh man been there soo many times, even with those heat set inserts lol!

How interesting! I'm building the tri-wheel rover like in the movie "Damnation Alley" in the past 2 months. Harder than I thought. Tolerances was the bitch. I use herringbone gears, pulleys and 2mm XL belts. I love fusion 360. Worked with SolidWorks for over 10 years and will never go back to it.

@JohnLauerGplus 2 года назад

You should use white lithium grease. Also, I'd put bearings on those middle gears. I'd put an outside bearing on the first gear as well. You should also look at a flat shaft so you can just match the flatness with your 3d print design and slide your gears onto the shaft. No need for set screws then because the pressure on those will warp your 3d prints, especially PLA, over time. I would also do all of the gears in nylon. I also don't think the inserts are worthwhile. Just tap the holes on the outside of the box. They'll be very strong.

@Papinak2 2 года назад

I think that outside bearing for the first gear is not necessary - shaft of the motor is already supported on 2 bearings, and lining up three bearings can be quite challenging. However, I'd use metal pinion gear, from some RC car that uses 0.8 or 1 mod gears, instead of printed gear.

@HarmanMotorWorks 2 года назад

Good idea with the threaded inserts. But if this is to be considered 'hobby-grade', it definitely needs a differential. Either geared or a ball-type; otherwise you're just gonna bind and really stress out those gears. And also - it'd be better to add ball bearings to all the moving parts.

Have you thought about using a gear oil r a atf as lube instead of grease. It’s lighter and you could fill the bottom with a inch or so and it will flow over all the gears n being lighter it might help the centrifugal drag. Idk just a thought hope it helps. I enjoy your videos

Is it better to use the "though pla" for high torqe gearboxes or is there no difference really? (it will be used outside in snow)

@quinnobi42 2 года назад

tough pla is a polymer blend that increases impact resistance, so it would be good for a bashing vehicle that sees a lot of hard acceleration. Maker's Muse has a video where he tests different materials for gear strength: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UtRJ4lnNAXY.html

Let me know if you want a design for an electric snowblower. I have a corded version that I think would be great for me to 3d scan for you. also, my 3d scan will be pictures, but still. It's angled higher than normal to keep everything electric safe, so if you're building triangle tracks, this could work.

you should keep the gearing but instead on onedriveshaft all the way thrugh you should usea differential

@piconano 2 года назад

I couldn't make the inserts work. They weren't strong enough and would pop out. So I put a nut in the middle, and now I can break the plastic by tightening the bolts too much. I was also told many years ago by a plastic engineer, not to use petroleum based grease on plastics, and only use white lithium grease. I complied.

@backgammonbacon 2 года назад

You need to make the hole for the insert smaller than the insert itself. a M3 insert needs only a 3.8mm hole. You also need to make sure the hole has thick enough walls. You also need to use the correct type of insert the ones meant for injection molding are crap. Done correctly they are stronger than the alternatives. Some of Let's Print holes are too large, if the smooth part at the start of the insert fits in the hole its too big.

@piconano 2 года назад

@@backgammonbacon The way I did it, as many others have, is to make room to insert a nut. If the bolt wants out, it either has to strip the nut, or break through 5mm of directionaly printed solid PLA. No need to buy anything extra. Which way do you thing is better?

@AcousticNRG 2 года назад

Not necessary spin the middle shafts and the friction is low between gear and shaft. just enough the final stage shaft spins. so he just use bearings on the final stage
