The structure of the harmonic reducer is that on the entire rigid wheel and flexible wheel, the teeth with the same modulus can be fully cut out. The most common gears mainly include larger fluctuations, and at the same time, they are in a concentric position during the entire transmission process. , the gap before each other is larger and the friction is less and less. Of course, on the long axis of the ellipse, the entire work height fits better, and it will show different states during operation. So what's unique about it?


First of all, the structure is very simple, the volume is small and the weight is light. Because the transmission of the harmonic reducer is mainly composed of three parts, mainly including the wave generator, the flexible wheel, the rigid wheel, etc., in the whole transmission process, it is better than the ordinary transmission reducer, the efficiency is higher, and the number of parts is relatively small. few. It is precisely because of this that the corresponding volume and weight are reduced by about one-third, and it has a high level of integration. The transmission ratio range is larger, and the current main categories include single-stage, double-stage, and amplitude wave reducer transmission ratios. Moreover, the number of gears is large. During the entire operation process, the specific number of gears is mainly controlled at about 30%. Compared with ordinary gears, the number of gears is increased by about two to seven percent. It is precisely because of the large number of gears that the precision of the harmonic reducer is higher, and the bearing capacity is large, which can realize the characteristics of large speed ratio and small volume.

The second is the large carrying capacity, because it has a large number of gears, so it has a strong carrying capacity. In the case of the same material and speed ratio, the carrying capacity far exceeds other transmissions, and the corresponding transmission range, Controlled to a few kilowatts. The motion accuracy is higher, and the corresponding motion accuracy is about four times higher than other types. And in the whole movement process, the stability is stronger. No shocks whatsoever, and less noise. It is precisely because the harmonic reducer has many advantages, so the corresponding use is more extensive.

Different from the general transmission equipment, the harmonic reducer has its own unique transmission mode. Although it has a small number of parts and a simple structure, its reduction ratio is very high and the transmission ratio is large. It has minimal backlash, which makes it easy to control the machine. In operation, due to the low meshing speed of each gear, the transmission is stable, the running noise is small, the vibration is small, the motion precision is high, and the fatigue resistance is strong. In daily use, the characteristics of the reducer should be clarified. Only by fully grasping the corresponding advantages can the corresponding efficiency be better brought into play.
