Shrink disk

The way shrink diskc work is based on the principle of frictional connection. A shrink disc consists of two conical rings that are pulled together by screws. When the screws are tightened, the inner ring is pressed onto the shaft. This pressure generates a high frictional force that ensures a reliable connection without play.

Advantages of the shrink disc shaft-hub connection

The shrink disc shaft-hub connection offers numerous advantages:

1. High transmission forces: Due to the high frictional forces, high torques can be transmitted.
2. Backlash-free and maintenance-free: The connection is virtually backlash-free and requires little to no maintenance.
3. Easy assembly and disassembly: Assembly is simple and the connection can be easily released if necessary.
4. No notch effect: No notch effects occur as no feather keys or keyways are required.

Areas of application for the shrink disc shaft-hub connection

The shrink disc shaft-hub connection is used in many areas:

1. Drive technology: In gearboxes, clutches and motors for the transmission of torques.
2. Conveyor technology: For conveyor belts and other transportation systems.
3. Heavy industry: In rolling mills, presses and other heavy machinery.
4. Wind turbines: For connecting rotor blades to the hub.

Shrink diskc compared to other types of joints

Compared to other types of connection such as feather keys, keyways or press connections, the shrink disc shaft-hub connection offers several advantages. It is more flexible, easier to assemble and disassemble and does not weaken the shaft due to notches. These properties make it a preferred choice in many industrial applications.
