Manufacturing Processes & Capabilities
- Micron-Precision Tooling & Micro-Module Accuracy: Covers M0.2 to M1.5 modules in both spur and helical tooth forms; micro-tolerance tooling ensures strict control over pitch-circle runout, tooth thickness uniformity, and pitch error for balanced multi-planet load sharing.
- Tight Bore Concentricity & Geometry Control: Pin bores are molded with strict diametrical and perpendicularity tolerances relative to the pitch circle, minimizing eccentricity and rotational drag during multi-gear meshing.
Features & Advantages
- Symmetrical Load Sharing & High Torque Density: Symmetrical multi-planet configurations evenly distribute torque across gear teeth, substantially boosting torque capacity and shock resistance within a compact envelope.
- Whisper-Quiet, Low Backlash & Smooth Operation: Spur profiles deliver high mechanical efficiency, while helical profiles provide gradual tooth engagement to eliminate meshing whine and vibration, ensuring smooth, low-backlash motion.
- Self-Lubricating, Wear-Resistant & Maintenance-Free: Engineered POM and Nylon resins provide low friction and high fatigue strength, ensuring long-term wear resistance and reliable operation in dry or minimally lubricated drivetrains.
