I. Main Features  

1. Material & Structural Properties  

   - Carbon Fiber/Glass Fiber Composite: Aerospace-grade fiber-reinforced polymer reduces weight by 60% compared to steel couplings while delivering high specific strength/stiffness and low rotational inertia.  

   - Flat Disc Pack Design: Optimized for transmitting high torsional vibration torques and radial forces, especially suited for high-speed applications (e.g., gensets) with speeds exceeding 10,000 rpm.  

   - Electrical Insulation & Non-Magnetic: Prevents stray currents from damaging bearings (e.g., shaft currents in generators) and ideal for EMI-sensitive environments.  

 

2. Mechanical & Dynamic Performance  

   - Low Reaction Forces & Linear Response: Near-linear disc deformation reduces bearing loads by up to 40%, extending drivetrain lifespan.  

   - High Misalignment Compensation: Single disc pack compensates angular/axial shifts; dual-disc configuration adds radial tolerance for installation errors/thermal expansion.  

   - Shock Absorption & Vibration Damping: High damping suppresses torsional vibrations; acoustically optimized models reduce noise for residential-area compliance.  

 

3. Environmental Resilience  

   - Maintenance-Free Operation: No lubrication required; corrosion-resistant in extreme temperatures (-45°C to 100°C), marine, and oil/gas environments.  

   - High Protection Rating: Standard IP65 (dust/water jet resistant); optional explosion-proof certification (ExiaⅡCT6) for hazardous areas.  

 

4. Installation Advantages  

   - Modular Design: Customizable dimensions (up to 3.5m diameter) and interfaces for complex spaces.  

   - Lightweight Construction: Simplifies hoisting and reduces installation costs.

II. Application Scope  

1. Wind Power  

   - Use Case: Mid-speed drivetrain coupling between gearbox and generator.  

   - Value: Electrical insulation prevents bearing corrosion; fatigue-resistant design increases turbine reliability by 30%.  

 

2. Marine Propulsion  

   - Use Case: Diesel-electric systems (engine-generator coupling) or elastically mounted propulsion motors.  

   - Value: Compensates hull deformation-induced misalignment; lightweight design cuts fuel consumption (ferries, cargo ships, high-speed vessels).  

 

3. Power Generation  

   - Use Case: Single-bearing gensets (close-coupled).  

   - Value: Balances axial displacement from gas/diesel engine thermal expansion; high damping protects generator rotors.  

 

4. Industry & Rail Transport  

   - Use Case: Railway traction motors, mining crushers, large pump systems.  

   - Value: Withstands dust, high-temperature oils, and shock loads; non-magnetic properties suit maglev drives.  

 

 

III. Technological Evolution & Positioning  

Carbon fiber membrane flexible coupling overcomes traditional coupling limitations via material-structure synergy:  

- Space Optimization: Eliminates intermediate bearing supports (patented design), reducing weight/space by 40%.  

- High-Speed Capability: Carbon fiber shafting achieves higher critical speeds than steel, enabling advanced marine/aviation APUs.  

Positioned as a premium drivetrain solution, it is the go-to replacement for rigid couplings in renewable energy and marine electrification.
