The original RINGFEDER® Locking Assemblies featuring double-tapered thrust rings with self-releasing tapers. They bridge relatively large fit clearances, are easy to install, adjust or remove, but are not self-centering. A pre-centering hub section is usually required.
The Locking Assemblies are supplied slightly oiled and ready-to-use. The values for T, Fax, pW and pN apply to Locking Assemblies in delivery condition.
For shafts and hub bores Ra = 3,2 μm
We recommend the following mounting tolerances
Shaft: k9-h9; Hub: N9-H9
Max. admissible Shaft: k11-h11; Hub: N11-H11
To avoid excessive deformations of the relatively thickwalled thrust rings, the Locking Assembly should be located as symmetrically as possible between shaft and hub bore. If the shaft is smaller than nominal d, the bore should exceed nominal D to the same extent and vice versa. The concentricity quality is determined by the direct centering between shaft and hub.
If several Locking Assemblies are to be installed the transmission values of the table can be added when the Locking Assemblies are located within a distance of 4·L.
The Locking Assemblies are equipped with 12.9 grade screws. A reduction of the screw tightening torque is possible. The lowest allowable screw tightening torque results from the multiplication of the TA-value by 0,5. There is an approximate linear relationship between T, TA , Fax, pW and pN.
To facilitate removal, the front thrust rings have auxiliary threads.
