Description

Technical Field

[0001] The present invention relates to a robot reducer, and in particular, it can provide a robot compound planetary gear intelligent variable reducer. Background Art

[0002] Existing robot harmonic reducers and RV reducers have complex processes and high costs. Summary of the Invention

[0003] In order to overcome the deficiencies of the existing robot reducers with complex processes and high costs, the present invention provides a robot compound planetary gear intelligent variable reducer with a parallel dual-drive and large speed ratio.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: Using the mechanism of planetary gears, the planetary gears on the planet carrier mesh with the ring gear and the sun gear. The motor is connected to the sun gear to input power, and the planet carrier outputs power. The ring gear is used for speed regulation. The speed regulation planetary gears with different tooth ratios mesh with the ring gears with different tooth ratios and the speed regulation sun gears with different tooth ratios. The speed regulation planet carrier is connected to the gear box to form a robot compound planetary gear intelligent variable reducer. When the motor rotates, it drives the two sun gears with different tooth ratios on the sun gear shaft to rotate and input power. The planetary gears mesh with the ring gear, and the planet carrier outputs power at a low speed. The speed regulation planetary gears with different tooth ratios mesh with the speed regulation sun gears with different tooth ratios and the ring gears with different tooth ratios for speed regulation. The speed regulation planet carrier is connected and fixed to the box body, and the reduction ratio is increased by using the tooth ratio difference of the two groups of planetary gears.
