    Harmonic drive applications

    Tips: Strain wave harmonic drive gearbox applications

    Strain wave harmonic drive gearboxes are used in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, commonly used ordnance, machine tools, instruments, electronic equipment, mining and metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical treatment Equipment and other aspects have been increasingly widely used, especially in the servo system with high dynamic performance, the use of harmonic gear transmission shows its superiority. It transmits power from tens of watts to tens of kilowatts, but high-power harmonic gear drives are mostly used for short-term work.

    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.
