    Strain Wave Harmonic Drive Gearbox Working Principle

     

    Harmonic gear transmission was invented by the American inventor CWMusser in 1955. The harmonic drive is a new type of transmission method that uses the elastic deformation of flexible working members to move or transmit power. It breaks through the use of rigid components in mechanical transmission. The mechanism mode uses a flexible component to achieve mechanical transmission, thereby obtaining a series of special functions that are difficult to achieve by other transmissions. Because the deformation process of the intermediate flexible component is basically a symmetrical harmonic, it is named. Except that the former Soviet Union called this kind of transmission flexible wheel transmission, the United States, Britain, Germany, Japan and other countries all called it "harmonic transmission".

    The Composition Of Gear TransmissionStrain wave harmonic drive gearbox

    • 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.

    Harmonic Gearing Transmission Deceleration Principle

     

    The principle of harmonic gearing is to use the relative movement of the flexible wheel, rigid wheel and wave generator, and the controllable elastic deformation of the main flexible wheel to realize movement and power transmission. The elliptical cam in the wave generator rotates in the flexspline to deform the flexspline. When the flexspline and rigid gear teeth at both ends of the long shaft of the elliptical cam of the wave generator come into engagement, both ends of the short shaft The teeth of the flexspline are separated from the teeth of the steel wheel. For the teeth between the long shaft and the short shaft of the wave generator, the different sections along the two circumferences of the flexible wheel and the rigid wheel are in a semi-engaged state that gradually enters the mesh, which is called meshing, and is in a state of gradually exiting the meshing half mesh. Called out. When the wave generator rotates continuously, the flexspline is continuously deformed, SO that the teeth of the two wheels continuously change their original working state in the four movements of meshing, meshing, meshing and disengaging, resulting in a staggered tooth movement, which realizes the initiative. The motion transfer from the wave generator to the flexspline.

    Features of Strain Wave Gear

     

    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.
