1. Feature: Inherent Attributes & Technical Foundation​

• Structure & Material: Adopts modular design, covering two mainstream structures: jaw type and all-steel gear type; jaw type uses 45# steel claw disc + polyurethane elastomer with adjustable hardness, all-steel gear type adopts forged steel gear sleeve + 304 stainless steel sealing components, with NBR 70 ShA O-ring as standard sealing system.​

• Precise Performance Parameters: Torque transmission range covers 15-2,750,000 Nm, adapting to rotation speed 0-15,000 rpm; compensable axial displacement ±2mm, radial displacement 0.5-2mm, angular displacement 0.5°-3°, balance accuracy up to AGMA Class 9 (Class 10-11 optional); applicable temperature -20℃-80℃, impact load resistance up to 1.5 times the rated torque.​

• Certifications & Adaptability: Complies with international standards such as AGMA 9008-B00 and API 671, some models pass ATEX explosion-proof certification; supports multiple installation methods including taper bushing, keyway, and hydraulic shrink disc, adapting to mainstream air compressor brands like Atlas Copco and Fusheng.​

2. Advantage: Performance Surpassing Industry Average​

• Superior Transmission Stability: All-steel gear type adopts crown gear meshing + permanent lubrication design, with transmission efficiency up to 99.8%, 3% higher than ordinary couplings; jaw type elastomer passes 100,000 impact tests, with vibration attenuation rate of 60%, which can reduce torsional vibration risk caused by inverter motor harmonics.​

• Stronger Durability & Adaptability: Forged steel material improves fatigue resistance by 2 times compared to cast iron (HT250), all-steel model has expected service life over 15,000 hours (ordinary models about 8,000 hours); elastomer can be quickly replaced without axially moving the half-coupling, improving maintenance efficiency by 70%.​

• Lower Installation & Maintenance Costs: Split structure design shortens installation time to within 20 minutes, saving 50% working hours compared to traditional couplings; fully sealed grease lubrication system reduces lubrication frequency by 90%, cutting annual maintenance costs by 40%.​

3. Benefit: Practical Value for Customers​

• Significant Cost Reduction & Efficiency Improvement: Long-life design reduces replacement frequency by 40%, saving over RMB 2,000 in spare parts costs annually for a single 110kW air compressor; low-loss transmission improves comprehensive equipment energy efficiency by 5%, saving up to RMB 3,500 or more in annual electricity fees.​

• Guarantee Production Stability & Safety: Displacement compensation function reduces shafting wear risk, lowering air compressor failure downtime rate by 65%; application cases in PDH units show it can completely eliminate shafting fracture risks caused by inverter harmonic torsional vibration, ensuring continuous production.​

• Reduce Operational Adaptation Risks: Wide torque range and multiple installation methods adapt to various air compressor models, reducing losses from incorrect selection; 24-hour rapid response service and standardized spare parts supply shorten maintenance waiting time to within 48 hours.​
