Shrink Discs RfN 4022
Key Features of Shrink Discs RfN 4022
The RfN 4022, also known as "thiết bị bóp trục RfN 4022", is arranged around the hub with a single transmission interface. It provides a highly concentric and balanced connection, making it ideal for high-speed applications. However, shrink discs require complex calculations, precise machining tolerances, and fine surface finishes, as well as considerable effort for mounting and dismounting.
- Inner Diameter (d): 11-440 mm, this range of diameters accommodates a wide variety of shaft sizes, providing flexibility for numerous industrial applications.
- Outer Diameter (D): 33.5-670 mm, suitable for a broad range of hub sizes, ensuring compatibility with different mechanical systems.
- Thrust Ring Width (L): 10-176 mm, this dimension allows for various thrust ring widths, contributing to secure and stable connections.
- Torque (T): 50-426,000 Nm, capable of handling torque values from low to extremely high, making it ideal for a variety of industrial applications requiring significant force transmission.
