From Ground to Space: Okly Gears Achieve Full-Range Application

Okly (Chongqing) Intelligent Equipment Technology Co., Ltd. has achieved a breakthrough in the full-range application of its precision gears, covering almost all high-end equipment fields—from ground transportation and marine engineering to aerospace and the low-altitude economy. These aerospace-grade magnesium-aluminum alloy gears maintain an ultra-high precision of ±3μm while achieving a reliability record of zero failures over 200 million cycles.

1 Ground Applications: A Reliable Foundation for Transportation and Industry

Okly's gears began their ground applications in industrial and transportation sectors. In industrial robotics, spur gears serve as key components in transmission systems, offering advantages such as simple structure, high transmission efficiency, and strong load-bearing capacity. They are widely used in joint drives, positioning systems, and actuators of industrial robots.

The new energy vehicle sector has become a major market for Okly. Its gear products are used in e-drive reduction gearboxes, improving NVH performance by 3dB and doubling lifespan. A representative from BYD's E-Drive Division stated, "Okly's gears have significantly enhanced the performance of our e-drive systems with their precision and reliability."

In industrial automation, cylindrical gears play an indispensable role in non-standard automated equipment. Okly's cylindrical gears offer smooth transmission, high efficiency, compact structure, and strong load-bearing capacity, making them suitable for high-speed, high-torque transmission requirements.

2 Marine Exploration: Overcoming Deep-Sea Corrosion Challenges

Okly has expanded into marine engineering, developing transmission gears for underwater equipment. These gears are made of corrosion-resistant materials, ensuring stable performance in high-salinity environments.

To meet the specific demands of deep-sea equipment, Okly's R&D team utilized micro-arc oxidation technology to reduce salt spray corrosion rates to 0.003mm/year, overcoming corrosion protection challenges. This technology enables the gears to withstand extreme pressure and environmental corrosion, providing reliable support for marine resource exploration and development.

3 Aerospace: Technological Leap from Ground to Space

The aerospace sector imposes extremely stringent requirements on gears, which Okly has met through multiple technological innovations.

In collaboration with Aerospace Science and Industry Corporation, Okly developed satellite deployment mechanism gear modules that achieve a fivefold increase in precision lifespan in vacuum environments, ensuring the reliability and accuracy of satellites in orbit.

The key technology of spatially variable thickness gear transmission systems meets the special requirements of the aerospace equipment manufacturing industry for gear transmission precision, efficiency, power density, and environmental adaptability. Through innovative engagement theory design and efficient precision machining technology, Okly has significantly improved the load-bearing capacity and precision of spatially variable thickness gear transmissions.

4 Low-Altitude Economy: Targeting Emerging Markets

With the rise of the low-altitude economy, Okly is actively expanding into the eVTOL (electric vertical take-off and landing aircraft) market, developing gears capable of withstanding -40°C extreme temperatures to meet the high torque density requirements of electric aircraft.

These gears must meet multiple demands, including extreme environment reliability, lightweight design, and high precision. Leveraging its technological expertise in aerospace gears, Okly has successfully developed transmission solutions that meet the needs of low-altitude aircraft.

5 Technological Innovation: Overcoming Material and Process Challenges

Okly's ability to achieve full-range applications stems from major breakthroughs in materials and processes.

Material Innovation: Using aerospace-grade magnesium-aluminum alloy (density 2.45g/cm³), optimized with yttrium-cerium rare-earth ratios, Okly reduced raw material costs by 15% while maintaining a compressive strength of 660MPa. Compared to traditional case-hardened steel gears, these gears are 68% lighter and offer a 150% longer fatigue life.

Precision Manufacturing: German KAPP five-axis grinding machines, paired with a proprietary intelligent compensation system, correct machining errors in real time. Laser interferometry checks every 30 minutes ensure tooth profile errors remain within ±3μm, meeting the highest accuracy standards of ISO1328.

Surface Enhancement: Aerospace-derived magnetorheological polishing technology achieves a tooth surface roughness of Ra0.2μm and surface residual compressive stress of -980MPa, significantly delaying the initiation of fatigue cracks.

6 Testing and Validation: Exceptional Performance in Extreme Environments

Okly gears undergo rigorous reliability testing:

• Endurance Test: 200 million cycles under rated load (equivalent to 15 years of HSR gate operation).

• Overload Test: 1 million cycles under 300% rated load impact.

• Environmental Test: Temperature variation tests from -40°C to 150°C.

• Contamination Test: Operation in highly polluted oil.

All test samples showed no pitting, spalling, or fractures, with wear under 2μm, fulfilling the promise of "maintenance-free throughout the entire service life."

7 Industry Impact: Redefining Gear Manufacturing Standards

Okly's breakthrough in full-range applications is having a profound impact:

Manufacturing Paradigm Shift: Large-scale integrated die-casting reduces gear production cycles from 72 hours to 4 hours, increasing yield rates to 99.5%. Flexible production lines allow switching between gears for different sectors on the same line, achieving 95% capacity utilization.

Cost Equation Restructuring: With magnesium prices stabilizing at ¥18,000/ton in 2025 (6% below aluminum), combined with process optimizations, magnesium-aluminum gears cost only 15% more than traditional products—while delivering a 300% increase in full lifecycle ROI.

Standardization Evolution: Participation in drafting the "Technical Specifications for Lightweight Gears in Transportation Equipment" has driven a 400% increase in the adoption rate of magnesium-aluminum alloys across multiple applications over three years.

8 Future Outlook: Infinite Possibilities from Earth to Interstellar Space

Okly is exploring broader application areas:

Space Exploration: Developing gear transmission systems suitable for extraterrestrial environments to support future interstellar exploration missions.

Smart Living: Applying high-tech gears to household appliances and smart home systems to enhance the performance and reliability of daily devices.

Medical Equipment: Researching precision gears for surgical robots and medical devices, meeting these fields' requirements for high precision, high reliability, and special environmental adaptability.

Okly's gear products have achieved full-range applications from ground to space, covering industrial robotics, new energy vehicles, precision machine tools, aerospace, marine engineering, and the low-altitude economy. As technology continues to advance and application areas expand, Okly is redefining the boundaries of gear manufacturing, providing critical support for the development of China's high-end equipment manufacturing industry.
