Main characteristics of harmonic reducer products

Let me introduce you to the 7 main features of harmonic reducer products. We usually use harmonic reducers in the field of machinery, and in order to adapt to general operations, they also have the following characteristics!
Harmonic Drive 

1. The transmission speed ratio is large. The single-stage harmonic gear transmission speed ratio range is 70-320, which can reach 1000 in some devices, and the multi-level transmission speed ratio can reach over 30000. It can not only be used for deceleration, but also for occasions of increasing speed.

2. High load-bearing capacity. This is because there are many teeth that mesh simultaneously in harmonic gear transmission, and the number of teeth that mesh simultaneously in double wave transmission can reach more than 30% of the total number of teeth. Moreover, the flexible gear uses high-strength materials, and the teeth are in surface contact.

3. High transmission accuracy. This is because there are many teeth engaged at the same time in harmonic gear transmission, and the error is averaged, that is, the multi tooth engagement has mutual compensation effect on the error, so the transmission accuracy is high. When the gear accuracy level is the same, 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 and even achieving no backlash meshing. Therefore, the harmonic gear reducer has a small transmission clearance and is suitable for reverse rotation.

4. High transmission efficiency and smooth movement. Due to the uniform radial movement of the flexible gear teeth during the transmission process, even if the input speed is very high, the relative slip speed of the gear teeth is still extremely low (which is -% of that of ordinary involute gear transmission), so the wear of the gear teeth is small and the efficiency is high (up to 69%~96%). Due to the engagement and disengagement, both sides of the gear engage in operation, resulting in no impact and smooth movement.

5. Simple structure, fewer parts, and convenient installation. There are only three basic components, and the input and output shafts are coaxial, so the structure is simple and installation is convenient.

6. Small size and light weight. Compared with general reducers, when the output torque is the same, the volume of harmonic gear reducers can be reduced by 2/3 and the weight can be reduced by 1/2.

7. It can transfer movement to confined space. By utilizing the flexible characteristics of flexible wheels, the valuable advantage of wheel drive is incomparable to other existing transmissions.
