Fairchild Harmonic Drive Draw Transmissions incorporate strain wave gearing principles which allow application of the unit in precise control of equipment. The Harmonic Drive has high torque capacity, zero backlash and high single stage ratio. The effect of tooth to tooth error is minimized with strain wave gearing since about 10% of the total teeth are always in engagement. This unit is an excellent choice for positional accuracy and repeatability in narrow draw applications (3.5% or less) such as web-offset printing.
