    Strain wave harmonic drive gearbox applications

    Harmonic drive applications

    Tips: The composition of gear transmission

    • Rigid wheel: rigid internal gear of harmonic drive usually 2 teeth more than the flexible wheel, usually fixed on the casing.
    • Flexible wheel: a thin cup-shaped metal elastic component with a gear on the outer ring of the opening, which deforms with the rotation of the wave generator, and is usually connected with the output shaft.
    • Wave generator: the wave generator of the harmonic drive consists of an elliptical cam and a flexible bearing, usually connected to the input shaft. The inner ring of the flexible bearing is fixed on the cam, and the outer ring can be elastically deformed into an ellipse through the ball.

    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.
