Technology Video: Harmonic Drive® strain wave gears are in a class of their own when it comes to motion control and mechanical power transmission. With operating principles and construction that maximize output torque and minimize size and weight, Harmonic Drive® 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. | |

Technology Video: Our expertise in the field of elasto-mechanics of metals is applied to the internal gear of the HPG, HPGP and HPF Series to provide the gearhead with continuous backlash compensation. Harmonic Planetary® gears use a precision engineered elastic ring gear. This proprietary Harmonic Planetary® gear design provides smooth and quiet motion and maintains ultra-low backlash for the life of the reducer. | |
