Hub Motor Planetary Gearbox
pt_094
Specifications
- Product Name: Hub Motor Planetary Gearbox
- Transmission Structure: High-strength precision planetary gear reduction system
- Materials:
Gears: High-performance engineering plastics (POM / PA66+GF / PEEK) with metal inserts
Housing/Carrier: Lightweight structural engineering components - Applications: E-Bikes (Pedelecs), Electric Scooters, and Light Electric Vehicle (LEV) hub motor assist systems
Manufacturing Processes & Capabilities
- Heavy-Duty Precision Gear Molding & Metal Inserts: Engineered for high torque demands, planetary gears are molded from wear-resistant, high-impact polymers (POM / PA66+GF) with integrated metal shaft/bushing inserts to maximize shear strength and torsional retention.
- Low-Backlash Profile Modification & Mold Flow Optimization: Advanced tooth profile optimization and mold flow analysis eliminate cooling shrinkage distortion, increasing tooth contact ratio for balanced stress distribution under heavy loads.
Features & Advantages
- Lightweight Compactness & High Torque Density: Sits seamlessly inside the hub motor shell; lightweight plastic gearing reduces unsprung mass while delivering robust torque for smooth starting and hill-climbing assist.
- Low-Noise Operation & Shock Absorption: High-performance plastic gears effectively absorb meshing vibration and high-frequency noise, delivering a whisper-quiet, smooth pedal-assist riding experience.
- Wear, Thermal & Weather Resistance: Superior fatigue resistance and environmental durability withstand outdoor riding conditions including temperature swings, rain, dust, and continuous road vibrations for extended, maintenance-free service.
