Operating Principals of Harmonic Drive™ Gearing

Three Basic ElementsThe diagram shows the three basic Harmonic Drive™ strain wave gearing elements CIRCULAR SPLINE - FLEXSPLINE - WAVE GENERATOR assembled in a normal configuration. Ordinarily, the Circular Spline is held stationary or fixed and input is through the Wave Generator, while output is via the Flexspline. Under these circumstances, operation is as follows. … Continue reading Operating Principals of Harmonic Drive™ Gearing →
