Locking Assembly RfN 7515 for bending loads

Especially for the bending moment transmission designed 3 part Locking Assembly with reduced stresses in the Locking Assembly itself.

Special Features - Through the long and flat cones one Locking Assembly RfN 7515 can transmit torques and axial forces and bending loads. At mounting is a small axial movement from Locking Assembly and hub.

Bending moment and radial loads – combined loads can be transmitted (Please contact our specialists for assistance).
Excellent centering ability – with a relatively wide design.
Example applications: Belt drums, gear wheels

If the pressures are too high for the application please note datasheets Mb 20% - Mb 80% with reduced bending moments.

Characteristics

Especially for the bending moment transmission designed 3 part Locking Assembly with reduced stresses in the Locking Assembly itself.

Explanation to table

A bending moment, created by radial forces, results in an additional load for the Locking Assembly, shaft and hub. This load creates an additional pressure, works in rotation and has to be superpositioned with the pressure resulting from the Locking Assembly. For a viable connection, a minimum surface pressure at the contact areas between Locking Assembly, shaft and hub must be maintained, as soon as shaft and hub have to take up the maximal pressures. Additionally, the listed torque values (T) have been reduced due to the additional bending moments. To achieve lower stresses for the Locking Assemblies the screw tightening torques (TA) have also been reduced.
