Cycloidal Gearbox

thingiverse

I've taken a stab at reimagining a Cycloidal gearbox, drawing inspiration from this YouTube video: https://www.youtube.com/watch?v=MBWkibie_5I. Initially, I utilized printed spur gears, which functioned perfectly until they disintegrated due to heat. I subsequently opted for metal ones instead. Fortunately, the cycloids seem to generate minimal heat and haven't presented any problems with ball bearings overheating. Nonetheless, lubricating the ball bearings is still a good idea.

I cut the 3mm dowel pins to size and ground a flat edge on the 8mm dowel pins to fit the eccentric part.
