The structure of the harmonic reducer is that it can fully cut out the teeth of the same modulus on the entire rigid wheel and flex wheel. The most common gears mainly include greater volatility and are in a concentric position throughout the transmission process. , The gap before each other is greater, the friction is less and less. Of course, on the long axis of the ellipse, the entire working height is more compatible, and it will show a different state during operation. What are its unique features?
   First of all, the structure is very simple, small in size and light in weight. Because the transmission of the harmonic reducer is mainly composed of three parts, mainly including the wave generator, flexible wheel, rigid wheel, etc., in the entire transmission process, it is better than the ordinary transmission reducer, the efficiency is higher, and the number of parts is higher less. Because of this, the corresponding volume and weight are reduced by about one-third, and it has a high integration. The transmission ratio range is larger, and the current main classifications include single-stage, double-stage, and amplitude-wave reducer transmission ratios. Moreover, the number of gears is relatively large. During the entire operation, the specific number of gears is mainly controlled at about 30%. Compared with ordinary gears, the number of gears increases by about two to seven percent. It is precisely because of the large number of gears that the harmonic reducer has a higher precision and at the same time has a large carrying capacity, which can achieve characteristics such as large speed ratio and small volume.
The second is the large carrying capacity. Because of its large number of gears, it has a strong carrying capacity. Under the same material and speed ratio, the ability to withstand is far beyond that of other transmissions, and the corresponding transmission range. Controlled at several kilowatts. The motion accuracy is higher. Compared with other types, the corresponding motion accuracy is improved about four times. And during the whole movement, the stability is stronger. There is no impact, and the noise is less. It is precisely because the harmonic reducer has many advantages, so the corresponding uses are more extensive.  
Unlike ordinary transmission equipment, harmonic reducers have their own unique transmission methods. Although the number of parts is small and the structure is simple, the reduction ratio is very high and the transmission ratio is large. Its backlash is extremely small, which makes it easy to control the machine. During operation, due to the low meshing peripheral speed of each gear, the transmission is stable, the operation noise is small, the vibration is small, the motion accuracy 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 played.
