AI Technical Summary

Technical Problem

In the prior art, the support bearing of the leg yaw joint is difficult to reliably and completely limit under compact assembly conditions, which affects the support stability and connection reliability, and the protection effect of the bearing area is difficult to achieve.

Method used

The output connection structure of the leg yaw joint is adopted. By setting a first bearing snap-fit ​​part, a second bearing snap-fit ​​part, a first bearing end cover and a second bearing end cover that cooperate with each other between the first housing, the leg yaw joint and the bearing, the bidirectional reliable limiting of the inner and outer rings of the bearing is realized. Combined with the matching arrangement of the mounting cavity, the bearing end cover and related components, a fully enclosed protection system is formed.

Benefits of technology

It improves the support stability and operational reliability of the leg yaw joint under complex loads, enhances the sealing protection of the bearing area, simplifies the structural design, reduces maintenance costs, and adapts to the compact installation requirements of humanoid robot leg joints.
