3. What is Shrink Disc RfN 4051?
The Ringfeder RfN 4051 is a three-part shrink disc designed to transmit low to moderate torque. Its compact design with narrow pressure rings requires minimal space. The amount of torque transferred can be precisely adjusted for specific applications by changing the screw tightening torque.
4. Characteristics of Shrink Disc Ringfeder RfN 4051:
– The Shrink Disc RfN 4051 is manufactured by Ringfeder/Germany.
– Inner diameter d: 125-500 mm.
– Outer diameter D: 185-750 mm.
– Total length L: 58-171 mm.
– Torque T: 10,550-1Mio Nm.
– The Ringfeder RfN 4051 shrink disc is a modern method for achieving appropriate mechanical tightening. Designed in three parts, it includes two pressure rings with tapered bores and one circular contact ring with a conical inner surface. Used for tightening locking screws, the pressure rings are pulled together to compress the inner ring, creating pressure on the outer surface of the shaft.
– Featuring a lightweight design, the shrink disc is placed around the hollow shaft to provide concentric connection, suitable balance for high-speed applications, and space-saving. It is easy to replace and install.
– When the locking screws are tightened, the contact surfaces are pressed together to prevent the ingress of dirt and moisture. The inner ring has grooves to minimize pressure and force on the hollow shaft and shaft. Suitable for both static and dynamic loads.
