Ball Screw R&D Expert (Humanoid Robot Direction)

Lead the forward design and R&D of micro, high-load ball screw pairs for humanoid robots; overcome key technical challenges in high load capacity and low friction at small scales.

"1. Forward Design: Lead R&D of micro, high-load ball screw pairs for humanoid robots, including thread parameter optimization, returner structure design, and preload/rigidity matching.

2. Performance Breakthroughs: Conquer key metrics such as high load capacity, low friction, low noise, and long life in compact sizes under high-frequency start-stop and impact loads.

3. Process & Testing: Collaborate with process teams on grinding, whirling, cold extrusion, etc.; build comprehensive ball screw test platforms (temperature rise, efficiency, stiffness, life).

4. Innovation: Research new materials (ceramics, special bearing steels), new lubrication methods, and special surface treatments to improve transmission efficiency and wear resistance.

5. Cross-Functional Collaboration: Work closely with motor, reducer, encoder, and control teams to complete integrated actuator design."
