To introduce you to the main 8 characteristics of harmonic gear products. We generally use harmonic reducers in the machine field, and he has the following characteristics in order to adapt to general operations!
2. High carrying capacity. This is because the number of teeth simultaneously meshed in the harmonic gear transmission is large, and the number of teeth simultaneously meshed in the double-wave transmission can reach more than 30% of the total number of teeth, and the flexible wheel uses high-strength materials, and the teeth are in surface contact with each other.
3. High transmission accuracy. This is because the number of teeth simultaneously meshed in the harmonic gear transmission is large, and the error is averaged, that is, the multi-tooth meshing has a mutual compensation effect on the error, so the transmission accuracy is high. In the case of the same gear accuracy level, the transmission error is only about 1/4 of the ordinary cylindrical gear transmission. At the same time, the radius of the wave generator can be changed by a small amount to increase the deformation of the flexible wheel so that the backlash is very small, and even backlash-free meshing can be achieved. Therefore, the harmonic gear has a small transmission loss and is suitable for reverse rotation.
4. High transmission efficiency and smooth movement. Due to the uniform radial movement of the flexwheel teeth during the transmission process, even if the input speed is high, the relative slip speed of the gear teeth is still extremely low (so it is a percent of the ordinary involute gear transmission -) Therefore, the gear tooth wear is small and the efficiency is high (up to 69%~96%). Since both sides of the gear are engaged in work when they are engaged and engaged, there is no impact and the movement is smooth.
5. Simple structure, few parts and easy installation. There are only three basic components, and the input and output shafts are coaxial, so the structure is simple and the installation is convenient.
6. Small size and light weight. Compared with the general reducer, when the output torque is the same, the volume of the harmonic gear can be reduced by 2/3, and the weight can be reduced by 1/2.
7. Can transmit motion to confined space. Taking advantage of the flexible characteristics of flexible wheels, this valuable advantage of wheel transmission is unmatched by other existing transmissions.
Harmonic gear
1. The transmission ratio is large. The speed ratio range of single-stage harmonic gear transmission is 70~320, which can reach 1000 in some devices, and the multi-stage transmission speed ratio can reach more than 30,000. It can be used not only for deceleration, but also for increasing speed.2. High carrying capacity.
