About the Harmonic Drive
This design is for my T^2 Tile project. Harmonic drives, featuring no backlash and unable to be back driven, were two very useful features. The mount has 32 teeth and the tpubelt has 30. The Output also has 30 teeth.
The M5 holes are 38mm square apart.
Drive size is 52x52x48.5mm and the minimum rotation avoiding it is 64.5mm.
