High Speed Harmonic Drive Gearing (.pdf)
with higher speed option. Harmonic drive gearing is a popular choice for many automation applications because of its superior power transmission qualities, which include zero backlash, high torsional stiffness,high positional accuracy, and torque-to-weight ratios. Until recently, however, the lowest gear
