Embodied robots (represented by humanoid robots)
Focus on “high flexibility, low weight, and fast dynamic response”
Embodied robots need to mimic human movements (walking, grasping, turning, etc.), have a large number of joints (20-30 degrees of freedom), and be able to quickly adjust their posture in dynamic environments (e.g., to avoid falling). Therefore, the core requirements for their reducers are extreme lightweight design, high dynamic response (millisecond-level torque adjustment), low noise, and sufficient load capacity (single-arm load of 5-10 kg).
☆ Hollow Cup Harmonic Reducer:
The preferred choice for fine joints such as fingers and wrists in humanoid robots.
Features: Features a hollow structure (facilitating wiring and sensor integration), weighing only 50–200 grams (60% lighter than industrial harmonic reducers); dynamic response speed improved to 2–3 times that of industrial models (torque adjustment delay < 10 milliseconds); optimized damping control via magnetic powder braking technology, suitable for precise operations (e.g., picking up eggs, twisting bottle caps).
☆ Frameless planetary reducer:
Used for medium-load joints such as legs and waist.
Features: Eliminates the housing, directly integrated with the motor rotor, reducing weight by 30%; gears use helical design, improving transmission efficiency to over 95% (reducing energy consumption); supports large-angle swinging (±120°), compatible with the movement range of human joints.
☆ New flexible reducer:
Developed by some manufacturers, combining the advantages of harmonic and planetary structures.
Features: Uses elastic gears + magnetic coupling design, eliminating physical contact wear, with a lifespan of over 10,000 hours; combines high rigidity (approaching RV reducers) and low weight (approaching harmonic reducers), suitable for core load-bearing joints such as the hip and shoulder joints.
Based on systematic research into the various oil seal structures used by leading international brands, UKS has combined its 20 years of technical expertise to continuously optimize and iterate its designs, resulting in the launch of UKS robot-specific oil seals. These oil seals are specifically designed for common operating conditions in robots, addressing the issue of conventional skeleton oil seals being unable to maintain stable sealing over the long term in narrow cross-sectional conditions.
Millimeter-level space conqueror
▸Narrow cross-section topological optimization design, breaking through the installation space limitations of traditional oil seals
▸Adaptive thin-walled structure compatible with micro-deformation of precision joints
Dual dust barrier
▸Outer dust lip: Effectively blocks external dust particles
▸Inner flexible compensation layer: Dynamically fills microscopic wear gaps
▸Based on dual radial force testing theory, seamlessly switches between dynamic and static sealing states
Wear coefficient theory and practice benchmark
▸Optimized material composition reduces wear coefficient to theoretical minimum
▸Triple composite structure design:
- Low-friction surface layer (reduces temperature rise)
- High-elasticity intermediate layer (compensates for deformation)
- Creep-resistant base layer (maintains radial force stability)
Robot oil seal rubber materials are mainly made of fluorocarbon rubber (FKM).
▸Excellent high-temperature resistance
The long-term operating temperature can reach 200℃, and special grades such as perfluoroelastomer (FFKM) can even maintain elasticity at 300℃.
▸Extremely strong chemical corrosion resistance
Highly resistant to strong acids (such as fuming nitric acid, concentrated sulfuric acid), strong alkalis, organic solvents (such as chlorinated hydrocarbons, high-aromatic gasoline), and oils, with minimal swelling or degradation.
▸Excellent aging resistance and vacuum performance
Resistant to ozone, ultraviolet light, and atmospheric aging, with stable performance even after ten years of natural storage.
▸Balanced mechanical properties and electrical insulation
Tear strength reaches 3–7 MPa, with elongation exceeding 600%, while also providing low-frequency electrical insulation capability.
Over the past two decades, UKS production system technicians have pioneered innovative solutions to address the scientific challenges associated with the dimensions and structure of elastomer oil seals. This breakthrough has resolved the long-standing concerns of rubber elastomer product manufacturers regarding product dimensional control. The resolution of rubber product dimensional consistency issues has propelled UKS oil seal product dimensional and structural scientific control into a phase of rapid development.
The essence of product consistency process lies in a three-tier system of “design standardization - process digitization - intelligent control,” which controls variations in the 4M1E (man, machine, material, method, environment) within acceptable ranges. The key implementation points include:
1. Establishing quantifiable process standards and traceable parameter records;
2. Utilizing detailed data accumulation to adjust and identify seal performance under different conditions in real time;
3. Leveraging IoT, AI, and other technologies to achieve real-time monitoring and predictive adjustments across the entire production process;
4. Utilizing two-dimensional imaging analysis equipment to comprehensively control defective products and achieve the goal of “zero defects” production.
☆ UKS holds more than 70 core technology patents;
