Project Background
As a global technological frontier, humanoid robots are rising rapidly. The Chinese robotics industry is facing a key challenge: Previously, over 90% of high-precision bearings used in robot joints were imported, leading to high costs and supply chain risks. In 2020, Luoyang Newbee Transmission Technology Co., Ltd. discovered the potential of humanoid robots and launched a research and development plan, committing to developing domestic alternatives for ultra-precision robot bearings. By 2025, the bearings of Newbee Transmission have become the core suppliers for leading domestic humanoid robot companies.
Technical Challenges
Humanoid robots require high-performance bearings to mimic human flexibility and endurance. The specific requirements are as follows:
1.Ultra-high precision: The rotational accuracy is ≤ 1 micron (1/60 of the diameter of a human hair), meeting the needs of delicate tasks such as embroidery.
2. Miniaturization and lightweight: Thin-walled design and compact structure to adapt to complex joint structures.
3. High rigidity and durability: Capable of withstanding high-frequency dynamic loads (such as jumping and flipping), with an operation cycle of more than 100,000 times.
4. Energy efficiency: Reducing friction and heat generation to extend battery life.
Innovative Research and Development Approaches
From 2020 to 2022, Newbee Transmission invested a large amount of manpower in the research and development of humanoid robot bearings.
The key breakthroughs achieved are as follows:
Technology | Implementation Method |
Precision Grinding | Adopting nanoscale CNC grinding machines with real-time feedback function to achieve a raceway roundness of ≤ 0.5 microns. |
Thin-walled Optimization | Using Finite Element Analysis (FEA) to optimize the bearing wall thickness without sacrificing rigidity. |
Material Innovation | Using high-carbon chromium steel and conducting vacuum quenching treatment to increase fatigue resistance by 30%. |
Lubrication System | Using low-viscosity grease with a ceramic-coated cage to reduce the friction torque by 25%. |
Accelerated Testing | Simulating 24-hour uninterrupted motion cycles to reach an operation duration equivalent to 5 years within 6 months. |
Key Achievements
1. Performance Indicators - Precision: The rotational error is ≤ 1 micron (ISO P4 grade).
2. Speed: Compatible with harmonic reducers with a maximum rotational speed of 10,000 revolutions per minute.
3. Service Life: Over 20,000 hours under dynamic loads.
4. Market Recognition: Certified by the National Robotics Quality Center.
Commercial Impact
1. Market Share: The proportion in domestic humanoid robot bearing categories (such as harmonic reducers and RV reducers) has increased.
2. Order Growth: The order amount in the first half of 2025 has surged, driving an annual revenue growth of 30% year-on-year.
3.Cost-effectiveness: Compared with imported alternatives, it reduces the procurement cost for customers by 30%.
Industry Significance
1. Supply Chain Security: Breaking the foreign monopoly on key components and supporting China's "Robotics +" national strategy.
2.Policy Recognition: Listed in the "Key Breakthroughs in Core Robotics Components" plan of the Ministry of Industry and Information Technology.
3.Global Competitiveness: The products can be benchmarked against international brands and are exported to Asian and European markets.
