The innovation of harmonic gear transmission technology brings another revolution in the field of mechanical transmission
As early as the 1950s, due to the rapid development of science and technology, a new technology appeared in the field of mechanical transmission, that is, harmonic gear transmission technology. The emergence of this technology is a breakthrough and meets the needs of new mechanical transmission. However, not many people understand this new technology. What are the excellent characteristics of gear transmission?
1. It has small volume, light weight and simple structure. Unlike other mechanical transmission structures, it requires complex structural design. It only includes three structural parts - wave generator, rigid wheel and flexible wheel. Such structural design can reduce the number of parts by as much as half and the volume and weight by at least one third compared with the traditional mechanical transmission structure.
2. More teeth are engaged at the same time. In the traditional mechanical transmission structure, the gear meshing number can only reach about 7%, while the gear meshing number in the harmonic gear transmission structure can reach 30% or even more. In this way, its transmission accuracy will be very high, and it can achieve large speed ratio and small volume.
3. In the process of harmonic gear transmission, the movement is very stable, there is almost no impact, and the noise will be very small. In the process of meshing in and meshing out, the teeth gradually enter and leave the rigid wheel through the flexible wheel buffer. In this way, the flexible effect makes the impact force smaller, so as to achieve the purpose of flexible buffer and no noise.
4. It can realize high growth movement. Its structural advantages lead to its small volume and light weight, but the traditional efficiency is very high. In this way, it can realize the movement process of high growth rate, and can be applied to the field of power generation, such as hand-operated generator, wind turbine and so on.
5. Differential motion can be achieved. Among its three basic components, any two components can be active and the other driven. If the rigid wheel and wave generator are active and the flexible wheel is driven, a differential transmission structure can be formed, so that fast and slow motion can be realized at the same time. This feature is often applied to the production of some machine tools.
Harmonic gear transmission is a great change in the field of mechanical transmission. Its many advantages make it more and more widely used. Through the introduction of this paper, I believe we have a deeper understanding of the advantages of harmonic gear transmission. In the future mechanical production and application, if it is necessary to achieve a variety of transmission purposes, it can be completed through such a structure.
