2.4 Precision planetary reducer: simple structure, good rigidity, high transmission efficiency

The precision planetary reducer is composed of planetary wheel, sun wheel and inner gear ring. The planetary gear transmission structure is the most efficient gear transmission structure. When the precision planetary reducer works, the original motor such as the servo motor drives the solar wheel to rotate, and then makes the planetary wheel rotate through the meshing with the planetary wheel, and then meshes the inner ring teeth inside the reducer shell through the planetary wheel, and finally the planetary wheel drives the planetary frame to rotate through the revolution, and the planetary frame and the output shaft necklace output torque.

Small volume and light weight: the traditional gear reducer needs a certain distance between the size of the gear, the overall space volume is large, and the planetary reducer can achieve repeated connection of the number of segments, effectively improving the space and volume problems. High efficiency and low back backlash: the planetary gear can achieve multi-point uniform close, and the outer gear ring is closely combined with the planetary gear, which improves the efficiency of the reducer.

5X00226G04 In summary, for the main indicators of the reducer: transmission efficiency: precision planetary reducer is the best, RV reducer is second, harmonic reducer ranks third; Transmission accuracy: precision planetary reducer is still the best, RV reducer and harmonic reducer comparable; In terms of transmission ratio: RV reducer and harmonic reducer are slightly better than precision planetary reducer.
