Flexible Wheel Wave Generator Robot Harmonic Reducer Fubao Whd20

 high reduction ratio flexible wheel wave generator robot harmonic reducer The coaxial robot joint small high precision reducer 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 two 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.

Advantages of harmonic reducer:

(1) Large transmission speed ratio. Single-stage harmonic gear transmission speed ratios range from 70 to 320. Some devices can reach 1000. Multistage transmission speed ratio can reach more than 30000. Not only can it be used to slow down, but it can also be used to accelerate.
 

(2) high bearing capacity. This is because the number of simultaneous meshing teeth in harmonic gear drive is more, the number of simultaneous meshing teeth in double wave drive can reach more than 30% of the total number of teeth. And the flexible wheel is made of high strength material, and the teeth are in contact with each other.
 

(3) High transmission precision. This is because the harmonic gear drive has multiple teeth meshing at the same time, the error is average, that is, the multi-tooth meshing can compensate each other's error, so the transmission precision is high. At the same gear precision 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 slightly changed to increase the deformation of the flexwheel, so that the side gap is small, and even the meshing without side gap can be realized. Therefore, the drive idling range of harmonic reducer is small, suitable for reverse rotation.
 

(4) High transmission efficiency, smooth movement. Due to the uniform radial motion of the flexible gear teeth in the transmission process, even if the input speed is very high, the relative sliding speed of the teeth is still very low (-% of the ordinary involute gear drive), so the wear of the teeth is small and the efficiency is high (up to 69% ~ 96%). Because both sides of the gear engage in the work, there is no impact phenomenon when meshing, the movement is stable.
 

(5) Simple structure, fewer parts, convenient installation. There are only three basic components, input and output shaft coaxial, simple structure, convenient installation.
 

(6) Small size, light weight. Compared with the general reducer, the volume of harmonic reducer can be reduced by 2/3 when the output torque is the same. The weight can be reduced by 1/2.
 

(7) Motion can be transmitted to confined space. Using the flexible characteristics of the flexible wheel, this valuable advantage of wheel drive is unmatched by other existing drives.
