Key Characteristics of the Steel Disc Couplings TND VDV
The Ringfeder TND VDV is a torsionally stiff, backlash-free steel disc coupling that includes two inverted hubs V connected by a spacer D of standardized length. High-strength screws are used to connect one disc pack to the spacer and one hub each, achieving the function of a double-cardanic system. It also known as "khớp nối đĩa đàn hồi TND VDV".
- TND VDV is available in 9 sizes, offering a wide range of options for different applications.
- The maximum bore diameter ranges from 25 to 120 mm (0.984 to 4.724 inches), accommodating various shaft sizes.
- The maximum outer diameter spans from 70.5 to 345 mm (2.776 to 13.583 inches), ensuring compatibility with different spatial constraints.
- The hub distance varies between 60 and 300 mm (2.362 to 11.811 inches), providing flexibility in installation.
- The overall length of the coupling ranges from 70 to 352 mm (2.756 to 13.858 inches), making it adaptable to different system requirements.
- It operates at maximum rotational speeds between 2,500 and 12,200 RPM, ensuring high-performance capabilities.
- The coupling can handle torque values from 170 to 44,000 Nm (125.36 to 32,452.73 ft·lb), making it suitable for a wide range of torque transmission needs.
