Materials commonly employed are high‑strength alloy steels such as 20CrNiMo7-6 and 30CrNiMo6-4, chosen for their fatigue resistance and corrosion protection.
EF Series Highlights
The EF series represents a breakthrough in universal joint design. Key features include:
- High‑Torque Capacity: Rated for up to 25,000 Nm, suitable for large‑scale wind turbines.
- Low Friction Coefficient: Achieved through advanced surface engineering and low‑temperature lubricants.
- Extended Service Life: Designed for 50,000 operational hours under continuous load.
- Compact Profile: Reduced mass and dimensions facilitate installation in constrained spaces.
Materials and Surface Treatments
Hangzhou ZhongYa employs a multi‑layer surface treatment process comprising nitriding, cryogenic hardening, and anodic oxidation. This combination enhances wear resistance, reduces vibration, and improves fatigue life. The company also offers optional coatings such as TiN and TiAlN for clients requiring superior oxidation protection in high‑temperature environments.
Design Innovations
Recent innovations include the integration of sensor modules into universal joint housings. These modules monitor temperature, vibration, and load in real time, transmitting data to a cloud‑based analytics platform. The information enables predictive maintenance and extends component lifespan.
