low price harmonic gear drive reducer&servo gearbox for 6 axis collaborative robot
The harmonic gear drive reducer&servo gearbox adopts WS tooth shape, which further optimizes the double circular arc tooth shape of the traditional theory. The tooth shape formed by the circular arc curve of the original 2 sections of curvature connection is optimized for the circular arc curve of the multi-section curvature connection, so as to ensure the correct meshing of the reducer gear and protect the risk of grease failure after extreme pressure by reducing the relative sliding friction. Based on WS tooth shape products, the bearing capacity is increased by 15%, the temperature rise is reduced by 8-10ºC, the gear fatigue pitting contact area is reduced by more than 30%, and the service life of continuous running is more than 15,000 hours, improving the comprehensive performance of harmonic reducer.
harmonic gear drive reducer&servo gearbox the movement is transmitted through the elastic deformation of the flex spline, mainly composed of 3 core components: the flex spline, the rigid spline, and the wave generator. Compared with RV and other precision reducers, the materials used in the harmonic reducer, The size and weight are greatly reduced.

Advantages of harmonic gear drive reducer&servo gearbox:
(1) The transmission speed ratio is large. The transmission speed ratio of single-stage harmonic gears ranges from 70 to 320. Some devices can reach 1000. The multi-stage transmission speed ratio can reach more than 30000. It can be used not only for deceleration, but also for acceleration.
(2) High bearing capacity. This is because the number of teeth meshing at the same time in the harmonic gear transmission is more, and the number of teeth meshing at the same time in the double wave transmission can reach more than 30% of the total number of teeth. Moreover, the flexible spline is made of high-strength materials, and the teeth are in surface contact.
(3) High transmission precision. This is because there are multiple teeth meshing at the same time in the harmonic gear transmission, and the error is average, that is, the meshing of multiple teeth can compensate each other for errors, so the transmission accuracy is high. Under the same gear precision level, the transmission error is only about 1/4 of that of ordinary cylindrical gear transmission. At the same time, the radius of the wave generator can be slightly changed to increase the deformation of the flexspline, so that the backlash is small, and even backlash-free meshing can be realized. Therefore, the transmission idling range of the harmonic reducer is small, and it is suitable for reverse rotation.
(4) High transmission efficiency and smooth movement. Since the flex gear teeth move at a uniform radial speed during the transmission process, even if the input speed is high, the relative sliding speed of the teeth is still extremely low (-% of ordinary involute gear transmission), so the wear of the teeth is small and the efficiency is high (up to 69% ~ 96%). Since both sides of the gears participate in the work when meshing, there is no impact phenomenon during meshing, and the movement is smooth.
(5) The structure is simple, the parts are few, and the installation is convenient. There are only 3 basic components, the input and output shafts are coaxial, 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 reducer can be reduced by 2/3 and the weight can be reduced by 1/2.
(7) Motion can be transmitted into confined spaces. Utilizing the flexible characteristics of the flexible spline, this valuable advantage of the wheel drive is unmatched by other existing drives.
