Gears paradoxical- engrenage paradoxal

thingiverse

After the spur and helical gears, I wanted to make a paradoxical gear. The result: it works. It's amazing how the wheels turn in the same direction. But it is possible. This is the CNAM at PARIS that manufactured the first one gear with two teeth, called paradoxical. I wanted to make four teeth and it works well. Nice to turn; no problem to print; simply ensure to properly adjust the gears on the axes. NOP21
