My own take on a Cycloidal gearbox, loosely based on this video i saw on youtube:
https://www.youtube.com/watch?v=MBWkibie_5I
Originally I used printed spur gears to drive it, which worked great until they melted.
I ended up purchasing some metal ones instead. The cycloids don't seem to generate much heat at all, and I have not had any problems with the ball bearings heating up. Still, lubricating the ball bearings would be a good idea.
Parts Needed:
Motor Mount
10x 40mm M3 Buttonhead screw
4x 10mm M4 Buttonhead screw
1x 200KV Brushless Motor 10mm shaft
1x 25 tooth spur gear 10mm bore; 20mm step; 1 mod

Cam x3
1x 25 tooth spur gear 8mm bore; 20mm step; 1 mod
2x 8x22x7 bearing 608ZZ skateboard
3x Spacer.stl
1x Eccentic.stl
1x 50mm 8mm pin
4x 20x27x4 bearing
Cycloid
15x Roller.stl
15x 33mm 4mm pins

Drive Plates

104x 5mm ball bearings
