    Harmonic Drive Gearbox Applications

    ATO harmonic drive gearboxes can be used to optimize the shape of robots, increase precision, increase strength, improve flexibility, etc., and are widely used in industrial robots, numerical control equipment, medical instruments, military and other fields.

    Harmonic drive applications

    Tips: Why is a harmonic drive gearbox so important for robots?

    The main function of a harmonic drive gearbox is to reduce the speed and increase the torque while ensuring that the equipment can reliably complete the process tasks and to ensure the positioning accuracy and reset positioning accuracy of the process when the same action is repeatedly performed.

    As the three main core components of industrial robot technology, harmonic reducer, AC/DC servo motor and controller directly determine the performance of industrial robots.

    The existence of the precision harmonic drive gearbox ensures that the motor runs at a suitable speed, and accurately reduces the speed to the speed required by various parts of the industrial robot, improving the rigidity of the mechanical body and outputting greater torque.

    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.
