The embedded intelligent planetary gear reducer comprises a shell and at least two stages of planetary gear sets, and the at least two stages of planetary gear sets are coaxially arranged; the number of the magnetic rings is at least two; the magnetic column set is arranged in the radial direction, the magnetic column set is matched with the starting end of the first-stage planetary gear set, one magnetic ring is matched with the tail end of the first-stage planetary gear set, and the remaining magnetic rings are matched with the tail ends of the remaining next-stage planetary gear sets; the number of the sensors is larger than or equal to the sum of the number of the magnetic rings and the number of the magnetic column sets, and the sensors are in one-to-one correspondence with the magnetic rings and the magnetic column sets to form an encoder. The problems that a planetary reducer is large in size, heavy in weight and low in precision are solved, the requirements for small size, large power, light weight and easy control of a reducer suitable for robot joints are met, and meanwhile the product cost and the production process difficulty can be effectively reduced.
Description
technical field [0001] The invention relates to a precision reducer, in particular to an embedded intelligent planetary gear reducer. Background technique [0002] The robot precision reducer is the core component of the robot. Compared with the general reducer, it is required to have the characteristics of small size, high power, light weight and easy control. At present, harmonic reducers and RV reducers are mainly used. The advantages of harmonic reducers are high precision, simple structure, and light weight. The problem is that as the use time increases, the motion accuracy will be significantly reduced, and the greater the torque, the faster the fatigue loss. , generally only has a service life of two years; compared with the harmonic reducer, the RV reducer has higher fatigue strength, stiffness and life, and has a larger output torque, but its disadvantages are complex structure, heavier weight than the harmonic reducer, and shape The size is larger than the harmoni...
