[0002] The precision right-angle planetary commutator is a high-precision, high-reliability transmission device, mainly used to change the transmission direction and speed. It has the characteristics of compact structure, high transmission accuracy and low noise. It is widely used in mechanical engineering, automation equipment and industrial robots. The precision right-angle planetary commutator can change the rotation direction of the input shaft to the vertical direction of the output shaft to achieve a change in transmission direction. It can be flexibly applied to various mechanical devices to meet the needs of transmission in different directions.

[0003] The function of the precision right-angle planetary commutator is to realize the reversing and deceleration functions, and improve the working efficiency and flexibility of the equipment.
