Revolutionizing Power Transmission for Aerospace & Advanced Mobility
The Orbicular Gear Mechanism (OGM)
20% Lighter, More Torque-Dense, Patented & Proven.
Problem
Rethinking Planetary Gear Design
Planetary gear systems—also known as epicyclic units—are vital to modern drivetrain technology. Their ability to deliver high torque in a compact footprint, while supporting multiple speed and load paths, makes them indispensable in automotive, aerospace, and industrial machinery.
Traditionally, planetary systems are built using external and internal cylindrical gears in a sun-ring-planet configuration. While effective, these systems have limitations—especially when designers need to:
- Maximize the number of planet gears
- Optimize load sharing and contact ratios
- Fit complex transmissions into tighter spaces
Face gears, on the other hand, offer clear advantages in many of these areas. By enabling torque transmission between non-parallel, non-intersecting shafts—often in orthogonal configurations—face gears support compact, lightweight, and low-noise solutions. Their unique geometry improves alignment flexibility and allows for broader tooth engagement, distributing loads more evenly.
However, until now, face gears were mostly used in isolated gear pairs—not in complete planetary architectures.

Our Breakthrough:The Orbicular Gear Mechanism
The Orbicular Gear Mechanism (OGM) is a novel, patented face-gear-based planetary system designed to overcome these fundamental challenges. By maximizing the number of planet gears relative to the reduction ratio, the OGM achieves unparalleled compactness and superior load distribution compared to traditional gearboxes. Its unique architecture, where the planet gears’ rotation axis is perpendicular to the gear mesh loads, redefines how centrifugal forces are managed, enabling robust high-speed mechanisms previously considered unfeasible.
This makes OGM a transformative alternative for a wide range of applications, transcending industry boundaries.
Superior Power Density & Weight Reduction
The OGM’s compact drivetrain architecture allows for a significant reduction in weight and size, creating a simplified and integrated lubrication system for optimum performance.
Modular, High-Durability Design
Easily mounted with low backlash, the system’s face gear pairs offer better durability and achieve higher contact ratios, significantly reducing Noise, Vibration, and Harshness (NVH).
High-Speed & Forgiving Alignment
Unlike traditional designs requiring micron-level precision, OGM sets do not need such stringent alignment, making them more practical to implement while performing reliably at high speeds.
Case Studies
Our engineering approach is not just theoretical; it is digitally validated. Each of our case studies features a fully developed digital prototype that has undergone rigorous analysis through kinematic and mechanical simulations using HyGEARS. The performance predictions are both robust and realistic. We are seeking partners to assist us in advancing the validation process to the physical prototype stage, supporting OEM-led research and development initiatives.
