Frictional shaft-hub-connections Why frictional shaft-hub-connections? Frictional shaft-hub-connections are standard machine elements used to connect shafts and hubs. They are capable of transmitting torque, axial forces, radial forces and bending moments. Shrink Discs and Cone Clamping Elements Among the frictional shaft-hub-connections Shrink Discs and Cone Clamping Elements take an important position. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces provide the required frictional connection between the parts involved in the transmission...

Categories of RINGSPANN shaft-hub-connections Shrink Discs Shrink Discs are external clamping connections for the backlash free fastening of hollow shafts or hubs to shafts. By tightening clamping screws conical surfaces are pulled together generating radial forces; these forces press the hollow shaft onto the shaft. Torques or axial forces can be transmitted frictionally from the hollow shaft to the shaft. The Shrink Disc itself is not involved in the transmission of torques or axial forces. The radial clamping forces which act through the circumference of the hollow shaft also ensure an optimum...

Ensured Torques with the RINGSPANN Calculation Method The RINGSPANN calculation method ensures that such errors in the dimensioning of shafthub-connections are avoided. This is achieved by using a method that has been tested and proven over many years, according to which the real friction coefficient μK in the contact Screw tightening torque Preload force Simplified calculation method without accounting for friction-coefficient fluctuations Standard Berechnungsmethode RINGSPANN Berechnungsmethode Example: M 10 screw, hardness rating 12.9 Screw tightening torque Preload force RINGSPANN calculation...

Online Calculation Tool shaft-hub-connections The new RINGSPANN Calculation Tool has been developed to work out the right and time-efficient dimensioning of an optimal shaft-hub-connection. Whether a Cone Clamping Element or a Shrink Disc, reliable results concerning the necessary hub dimensions and bearing pressures can be determined within a few minutes, as well as the transmissible torques and axial forces for differ ent strengths, torques and numbers of screws. This means that any oversizing or undersizing of the elements can be avoided and a costoptimised solution found for the application...

Design and Function of Shrink Discs Two-part Shrink Discs Design and Function Two-part shrink discs consist of an outer stepped conical ring, and an inner stepped conical bush, as well as a number of clamping screws (see Figure 10-1). Hollow shaft The stepped conical ring is pulled onto the stepped conical bush by tightening the clamping screws. A radial clamping force is generated by the conical surfaces, which is independent of the friction coefficients at the screws and conical surfaces. The radial clamping force presses the hollow shaft onto the shaft and creates a frictional connection at...

Design and Function of Shrink Discs Three-part Shrink Discs Threaded flange Pressure flange Three-part shrink discs consist of a threaded flange, a pressure flange, a slotted inner ring and a number of clamping screws (see figure 11-1). Inner ring Hollow shaft Shaft Clamping screws The threaded flange and the pressure flange are pulled together over the inner ring by tightening the clamping screws. A radial clamping force is generated by the conical surfaces which is dependent on the friction coefficients at the screws and conical surfaces. The radial clamping force presses the hollow shaft onto...
