Harmonic Drive vs Planetary Gear: Complete Engineering Comparison [ez-toc] Quick Answer A harmonic drive (strain wave gear) uses the controlled elastic deformation of a flexspline to achieve single-stage reduction ratios of 50:1–320:1 with near-zero backlash (≤1 arc-min), while a planetary gear uses rigid sun-planet-ring gear meshing to deliver multi-stage ratios of 3:1–100:1 with higher torque density and efficiency up to 98% per stage
