AboutHarmonic Drive Reducer The Principle of Gear Transmission Harmonic gear transmission was invented by the American inventor C.W.Musser in 1955. It is a new type of transmission that utilizes the elastic deformation of the flexible working member into the motion or power transmission. It breaks through the mechanical transmission using rigid members. The mechanism’s model uses a flexible member to achieve mechanical transmission, resulting in a range of special features that are difficult to achieve with other transmissions. The deformation process of the intermediate flexible member is basically a symmetrical harmonic. In addition to the former Soviet Union referred to this type of transmission as wave drive or flexible wheel drive, the United States, Britain, Germany, Japan and other countries are called "harmonic transmission." The Composition of the Gear Transmission Circular Spline: it has two more teeth than the Flexspline and is generally mounted onto a housing. Flexspline: It is a non-rigid, thin cylindrical cup with external teeth on the open end of the cup. It fits over the Wave Generator and takes on its elliptical shape. The Flexspline is generally used as the output of the gear. Wave Generator: The Wave Generator is a thin, raced-ball bearing fitted onto an elliptical hub. This serves as a high-efficiency torque converter and is generally mounted onto the input or motor shaft. Principle of Harmonic Gear Reductor The principle of harmonic gear reduction is to use the relative motion of the Flexspline, Circular Spline and the wave generator, mainly the controllable elastic deformation of the flexspline to realize the motion and power transmission. The elliptical cam in the wave generator rotates in the flexible wheel to deform the flexspline. When the Flexspline teeth and the Circular Spline teeth enter and mesh with each other which are at the ends of the elliptical cam long axis of the wave generator, the Flexspline teeth at short axis ends are disengaged from the steel wheel teeth. For the teeth between the long axis and the short axis of the wave generator, the semi-engaged state which gradually enters the engagement along different sections of the two stages of the Flexspline and the Circular Spline is called a biting. It is in a state of gradual withdrawal from engagement, which is called disengaging. When the wave generator rotates continuously, the flexspline is constantly deformed, so that the teeth of two wheels are constantly changing their original working states during the four movements of meshing, biting, engaging and disengaging, generating a staggering tooth movement and realizing the motion transmission from the wave generator to the flexspline.

Product Uses

Harmonic gear reducer in aviation, aerospace, energy, navigation, shipbuilding, bionic machinery, commonly used ordnance, machine tools, instruments, electronic equipment, mine metallurgy, transportation, lifting machinery, petrochemical machinery, textile machinery, agricultural machinery and medical equipment are increasingly widely used, especially in the high dynamic performance servo system, the 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 in short-term work fields.
