OpenRC 1:10 RC Differential by barspin Nov 20, 2012

Featured Thing!

Description

Inspired by Thing-O-Fun's "Functional Differential Gear System" I decided i should make one for my RC car. So i did.

I scaled down the gears from the above mentioned Thing, and designed the rest of the parts in my favourite cad software.

And it works surprisingly well, my car is 4WD so i have two of these in the car right now!

What material did you use? I am sure these gears get hot so I am curious if they melt.
Impressive! I am designing a differential for an RC car competition. I want to make the housing out of plastic, but buy metal gears to increase fatigue life. What CAD software did you use? Can I get your part files so that I can take a closer look at your design?
brilliant design! I have just printed two bevel gears and they are awesome!!

Instructions

The parts may have some adjustments done to fit the settings of my printer so you might have to do some adjustments of your own to make it fit correctly.

The "Side Gear Axle" is made of 3mm stainless steel.

Other than that check out the exploded view PDF to see how it´s assembled.

I made this as an experiment so you should consider it as beeing such a thing.

Nice work. From your last photo I guess you got more printed parts on your car. I hope you are going to release that too :-)
That is a superb bit of plastic engineering. 

I love it.
Excited to see OpenRC!  Looking forward to more releases!
Open RC, that looks fun, I'm testing some wheels at the moment: https://plus.google.com/117720739261688507735/posts/QoBRToHfFmx
I made one this morning and it works well.
Awesome! Would you mind posting a picture? :-)
Brilliant design! From the photo your car looks heavily 3D printed so any chance of releasing the car designs as well!
Thanks! Well your right and it´s my intention to do so but i´m gonna hold that one for a bit though. ;-) I have more stuff coming from my "Open RC" project later...
wow, I seriously cannot wait to have a majorly-3d printable RC car.  So many awesome things could be accomplished.
