Harmonic drive maker
A strain wave gear with a printed flexible cup.
About the harmonic drive maker
A harmonic (strain wave) drive gives a very high ratio in one flat stage. This makes the outer ring, the flexible toothed cup and the wave generator, sized from the outside diameter and ratio.
- Print the cup in a flexible, tough material; PLA cracks.
- The ratio is half the number of teeth on the cup.
- It has not been test-printed: expect to tune the cup wall and the fit.
