    Tips: Features of strain wave harmonic drive gearbox

    ATO strain wave harmonic drive gearbox adopts S-shaped optimized involute tooth structure, meshing is smoother and more stable, and the tooth profile processing of rigid-flexible wheels breaks through the traditional slow wire-traveling and gear hobbing processes. With the special process of gear hobbing semi-finishing + smoothing and trimming the tooth surface accuracy; breaking the status quo of relying on imported machine tools and imported tools, the independent core technology is low-cost and high-yield to form a mass-production scale quickly.

    Installation Manual

    PDFATO Harmonic Drive Gearbox Installation Manual

    Precautions for installation

    1. When the harmonic drive gearbox is in use, if the output end is horizontally downward, the lubricating grease injected into the inner wall space of the flexspline must exceed the meshing tooth surface.
    2. The installation plane of the rigid wheel and the rigid wheel connection and the installation plane of the flexible wheel and the flexible wheel need to be statically sealed to ensure that the grease will not leak during the use of the harmonic drive gearbox and avoid the reducer from working with little or no oil Time damage.
    3. During the installation process, please do not knock the parts of the harmonic drive gearbox with hard objects, or apply strong pressure to avoid damage to the parts.
    4. If you have any questions during the inspection, please contact ATO.

    Tips for using a harmonic drive gearbox

    • Please use it in the specified environment.
      Observe the following conditions when using a harmonic drive gearbox:
      Ambient temperature: 0-40 degrees Celsius, no splashes of water, oil, etc.; no corrosive, explosive gas; no dust such as metal powder,
    • Please use the prescribed method for installation.
      Please implement the installation method correctly according to the harmonic drive gearbox manual. If it is not installed correctly, it may cause vibration, loss of accuracy, shortened service life, damage and other failures.
    • Please use the specified lubricant.
      Failure to use the specified lubricant may result in reduced harmonic drive gearbox life.
      Please do not disassemble or reassemble the product, otherwise, it will not be able to restore its original performance.
      Do not exceed the allowable torque during use, otherwise, it may cause harmonic drive gearbox failure.
