Internal gears and gear rings provide internal tooth engagement for compact and concentric power transmission. Commonly used in planetary gear systems and precision rotary motion modules.
Wu Hung's Planetary Internal Gear Rings deliver compact, concentric power transmission for planetary gear systems, robotics, and e-bike hubs. CE & RoHS compliant, they offer custom tooth profiles (spur, helical, spline) with tight tolerances via shaping or broaching.
Hardened or plastic-compatible options ensure quiet, low-backlash operation. Reverse engineering and small-lot prototyping available with AGMA/DIN-certified geometry and full material/inspection reports. Please do not hesitate to contact us for further details.
Features:
- Custom involute, spline, or serrated tooth profiles
- Precision shaping/broaching for tight tolerances
- Quiet, compact design with minimal backlash
- Hardened, ground, or plastic-compatible profiles
- Ideal for co-axial, space-saving transmission
Applications:
- Planetary gear systems
- Robotics and AGV drive rings
- E-bike/scooter gear hubs
- Hydraulic/rotary actuators
- Aerospace/instrumentation modules
