LHT - III Series Strain Wave Reducer Harmonic Gears
Product description
A harmonic drive is backlash-free with a high-ratio of speed reduction by design. This is advantageous for systems that require precise gear positioning.
The base shaft turns the strain wave generator, which is elliptical with bearings around the circumference.
With operating principles and construction that maximize output torque and minimize size and weight,
harmonic 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.
| Features 1. High Precision and Repeatability: Essential for applications requiring exact positioning and control. 2. Compact Size: Saves space, allowing for more compact and lightweight designs. 3. High Torque-to-Weight Ratio: Provides strong torque output without significant weight. 4. Low Wear and Long Life: Due to the rolling contact of teeth, which minimizes wear and extends the lifespan of the drive. 5. Smooth Operation: Provides smooth and consistent motion, ideal for delicate tasks. |
