Harmonic Reducer RHSG series

Product Features

  • High Precision:

    Multiple teeth mesh simultaneously at two 180-degree symmetrical positions. Therefore, the impact of gear pitch errors and cumulative pitch errors on rotational accuracy is more evenly distributed, resulting in extremely high positional and rotational accuracy.

  • High Transmission Ratio:

    The transmission ratio of a single-stage harmonic gear drive can reach i=30-500. Its simple structure, with only three coaxial basic components, can achieve a high reduction ratio.

  • High Load Capacity:

    In harmonic drive, teeth mesh with each other through surface contact, and the large number of teeth meshing simultaneously results in a low load per unit area, resulting in a higher load capacity than other transmission types.

  • Small Size and Light Weight:

    Compared to conventional gear systems, the size and weight can be significantly reduced, enabling miniaturization.

  • High Transmission Efficiency and Long Service Life.
  • Smooth, Shock-Free, and Low-Noise Drive.
