How Does Harmonic Reducer Work Well?

Many factories and enterprises often use harmonic reducers without knowing how they work. This lack of understanding can cause delays in machine operation when problems arise and professional maintenance personnel cannot be found. Therefore, understanding the principle of how harmonic reducers work is crucial.
 

What kind of components does a harmonic reducer use?

Harmonic reducers mainly use the principle of harmonic reducer transmission, which allows flexible machine elements within the harmonic reducer to undergo controlled elastic deformation to transfer motion. The harmonic transmission process requires three basic components: the rigid wheel, the flexible wheel, and the wave generator. These three components work together, and one of them can be fixed while the other two can be in either a passive or active state, achieving machine speed increase or decrease under a fixed transmission ratio. Alternatively, two components can be used as input and output, forming a differential transmission to ensure machine speed.
 

What is the relationship between the components?

In the active and passive states, we can choose the wave generator as the active component and the flexible wheel as the passive component. During normal operation, the flexible wheel deforms under the strong action of the cam. As the flexible wheel is located at both ends of the wave generator, its teeth mesh with the fixed teeth of the rigid wheel while disengaging from the short end of the flexible wheel. As the active wave generator continuously rotates, the harmonic reducer's gearbox undergoes meshing, engagement, disengagement, and release of teeth, continuously operating according to a corresponding law and achieving machine speed reduction based on the reduction ratio.
 
Understanding the operating principle of harmonic reducers, we know that they have been widely used in many industries due to their technological advantages. In addition to industrial machines, harmonic reducers are also used in aerospace, military manufacturing, medical electronic equipment, and more. In short, the application scope of harmonic reducers is extensive and will continue to develop rapidly in the coming years.

 
In summary, Harmonic reducers use flexible machine elements to transfer motion through harmonic transmission. Its three basic components, the rigid wheel, flexible wheel, and wave generator, work together to achieve machine speed increase or decrease under a fixed transmission ratio. The wave generator is the active component, and the flexible wheel is the passive component. As the wave generator continuously rotates, the harmonic reducer's gearbox undergoes meshing, engagement, disengagement, and release of teeth, achieving machine speed reduction based on the reduction ratio. Harmonic reducers are widely used in many industries, including industrial machines, aerospace, military manufacturing, and medical electronic equipment, due to their technological advantages.
