While ensuring the motor operates at the appropriate speed, precisely reducing the motor speed to the speed required by the equipment, it can also increase the rigidity of the mechanical body while outputting greater torque. This is an effect that ordinary reducers can achieve. Why must a harmonic reducer be selected? What irreplaceable characteristics does a harmonic reducer possess? Today, a harmonic reducer manufacturer will introduce the irreplaceable characteristics of harmonic reducers. Let's take a look. The harmonic reducer manufacturer explains that the flexible wheel teeth move uniformly radially during transmission, even if the input speed is very high, the relative sliding speed of the teeth is still extremely low (one percent of ordinary involute gear transmission). Therefore, the tooth wear is small, and the efficiency is high (70%~95%).

　　Since both sides of the gear participate in work during meshing and de-meshing, there is no impact phenomenon, and the movement is smooth. Using the flexibility of the flexible wheel for harmonic transmission can transmit motion to a closed space, which is unmatched by other transmissions. The main function of the harmonic reducer is to reduce speed and increase torque while ensuring that the equipment can reliably complete the process tasks. When repeatedly performing the same actions, it can ensure the positioning accuracy and repeatability of the process. The harmonic reducer manufacturer tells you that compared with ordinary reducers, with the same output torque, the volume of the harmonic reducer can be reduced by 2/3, and the weight can be reduced by 1/2. It only has three basic components: a wave generator, a flexible wheel, and a rigid wheel, and the input and output shafts are coaxial, so the structure is simple and easy to install.

　　The speed ratio range of a single-stage harmonic gear transmission is 69~330, which can reach 990 in some devices. The multi-stage transmission speed ratio can reach more than 31000. Many teeth are engaged simultaneously during harmonic gear transmission. In double-wave transmission, the number of teeth engaged simultaneously can reach more than 30% of the total number of teeth. The flexible wheel uses high-strength materials, and the teeth are in point contact. The large number of simultaneously engaged teeth in harmonic gear transmission averages out the error, that is, the multi-tooth engagement has a mutual compensation effect on the error, so the transmission accuracy is high. The harmonic reducer manufacturer reveals that under the same gear accuracy level, the transmission error is only about 1/4 of that of ordinary cylindrical gear transmission. At the same time, a slight change in the radius of the wave generator can be used to increase the deformation of the flexible wheel, making the backlash very small, or even achieving backlash-free meshing. Therefore, the harmonic gear reducer has a small transmission clearance and is suitable for reverse rotation.
