Simple no reduction transfer case for RC 4x4 vehicle.


Materials required:
5x11 bearing X6
5mm drill rod X3 (length changed to suite requirements)
13t 5mm pinion gears X3
3mmx10mm screw X4 to mount to vehicle
2mmx10mm screw X8 (or equivalent small size)

Pinion gears ordered from: http://www.hobbyking.com

13T/5mm M1Steel Pinion Gear

Cut 3 lengths of drill rod. 35mm, 22mm, and 45mm. If you want you could make the shafts that exit the case longer to suite your needs. You will need to mark and file flat spots on the drill rod for the pinion grub screws and the driveshafts to clamp on to the shafts.

The holes for bolting on the lid were drawn as 1mm by 10mm deep so that you can drill and tap to whatever size screws you plan on using.

Have you since done anymore work with this? Have you actually made it and tested yet?

The Hobbycraft link you posted doesn't work- it is the correct link display-wise but I think something got lost in translation- perhaps the thingiverse posting mechanism broke the url?

Also, it would be nice to see this part fully assembled. Do you have any pictures of one you've printed/built yourself?

Other than that, good effort. :)

Weird I tried to edit it a couple times but it doesn't appear to like external links. I included the information so you could easily search for the pinions I used.

I have yet to print this and try it out. Hoping to get to it today.
