Speaking of harmonic gearboxes, some people may not know much about them. It doesn't matter. Although this new type of mechanism is not widely used in the market at present, it is believed that it will be widely used in all walks of life in the near future. Harmonic gearbox completes transmission function by virtue of elastic deformation movement. Different from the traditional mechanical transmission, this kind of transmission uses the rigid member mechanism. A flexible component inside makes it possible to successfully complete the mechanical transmission and solves many problems that are not encountered in the design.

1. The Origin of Harmonic Gearbox

In fact, harmonic gearbox appeared in the middle of last century. At that time, it was used in aerospace field. The aviation field needs some mechanical transmissions with large transmission ratio, small size, light weight, high transmission precision and small return difference. Therefore, someone invented the harmonic gearbox. It consists of three basic components: rigid wheel, flexible wheel and wave generator. In the flexible gear, the moving deformation wave appears with the help of the wave generator, which meshes with the rigid gear teeth and finally realizes the transmission.

2. Advantages of Harmonic Gearbox

The advantages of harmonic gearbox are remarkable. It has a wide range of transmission ratio, a large number of meshing teeth, and small and uniform tooth surface wear, so the whole harmonic gear has high transmission precision, high motion precision, high transmission efficiency and great bearing capacity. It has the unique performance of large speed ratio and small volume. At the same time, the transmission is stable with no impact and small noise. If necessary, you can freely adjust the gap between the teeth sides. It can also transmit motion or power to a closed space.

However, the components of harmonic gearbox, flexible wheel and wave generator, are difficult to manufacture, so they are very expensive. Moreover, the required transmission ratio should not be low and the number of teeth should not be small, otherwise fatigue damage will easily occur. At the same time, there is no intermediate speed because it does not have the structure of intermediate shaft. You should pay attention when using it.

Therefore, we should choose harmonic gearboxes with high speed, reasonable structural parameters, low heat generation and large transmission bearing capacity, thus prolonging the service life of the machine and ensuring the safety of operators.
