Why do high precision industrial robots install harmonic reducers?
In industrial robots, harmonic reducers are indispensable. Why? This is also to talk about its advantages. Next, the harmonic reducer manufacturers summarized the characteristics of harmonic drive to share with everyone.
(1) Large transmission speed ratio
The single-stage harmonic gear transmission speed ratio ranges from 70 to 320, and 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 speed increase.
(2) High loading capacity
This is because the number of gear engaged in the harmonic gear transmission is large at the same time, and the number of gear of the double-wave transmission simultaneously meshes to more than 30% of the total number of gear, and the flexible wheel adopts a high-strength material, and the gear are in surface contact with the gear.
(3) High transmission accuracy
The number of gear meshed at the same time in the harmonic gear transmission is large, and the error is averaged, that is, the multi-tooth meshing has mutual compensation effect on the error, so the transmission precision is high. In the case of the same gear accuracy grade, the transmission error is only about 1/4 of the ordinary spur gear transmission. At the same time, the radius of the wave generator can be used to increase the deformation of the flexible wheel so that the backlash is small, and even the backlash can be meshed. Therefore, the harmonic gear reducer has a small free motion and is suitable for reverse rotation.
(4) High transmission efficiency and smooth motion
Due to the uniform radial movement of the flex wheel teeth during the transmission process, even if the input speed is high, the relative slip speed of the gear teeth is extremely low (so the percentage of the ordinary involutes gear transmission -) Therefore, the gear teeth are small and the efficiency is high (up to 69%~96%). Moreover, due to the engagement and the biting, both sides of the gear participate in the work, so there is no impact phenomenon and the movement is stable.
(5) Simple structure, few parts, easy to install
There are only three basic components, and the input and output shafts are coaxial, so the structure is simple and easy to install.
(6) Small size and light weight
Compared with the general reducer, when the output torque is the same, the volume of the harmonic gear reducer can be reduced by 2/3 and the weight can be reduced by 1/2.
(7) can transmit motion to the confined space
Taking advantage of the flexible nature of the flexible wheel, this valuable advantage of the wheel drive is unmatched by other existing drives.
As long as so many advantages of the harmonic reducer can be applied to high-precision industrial robots. If you have any demand for this harmonic drive, please contact GIGAGER harmonic reducer manufacturers.
