High Precision Model 32 Sealed Harmonic Gears
Product description
Harmonic reducers are in a class of their own when it comes to
motion control and mechanical power transmission.
The strain wave reducer gears offer advantages such as high
reduction ratios in a single stage, zero backlash, and high
precision that cannot be equaled by conventional gear trains.
The strain wave gearing uses the elasticity of metal. The harmonic
reducer gears have three basic components: a wave generator, a flex
spline , and a circular spline.
How it works
The Flexspline is slightly smaller in diameter and has two fewer
teeth than the Circular Spline. The elliptical shape of the Wave
Generator causes the teeth of the Flexspline to engage the Circular
Spline at two opposite regions across the major axis of the
ellipse. For every 180 degree clockwise rotation of the Wave
Generator the Flexspline teeth are advanced counterclockwise by one
tooth in relation to the Circular Spline. Each complete clockwise
rotation of the Wave Generator results in the Flexspline moving
counter-clockwise by two teeth from its original position relative
to the Circular Spline
