AI Technical Summary
Existing industrial robot joint connectors suffer from stress concentration due to their rigid structure, which affects their service life and motion accuracy, making it difficult to achieve efficient multi-axis linkage.
The design incorporates flexible connection modules, transmission components, and drive components. Flexible sheets, support rings, and ball bearing structures are used to disperse stress, and gear transmission and base vibration damping are optimized to achieve multi-degree-of-freedom coordinated motion.
It improves the motion accuracy and flexibility of the robotic arm, reduces stress concentration, extends service life, and enhances the reliability and stability of multi-axis linkage.
