Locking Assembly RfN 7012/RfN 7012-IN · Typical installation

Characteristics

As the industry standard, the RfN 7012/RfN 7012-IN Locking Assembly is suitable for most applications. Transmission of high loads ­ up to 4 RfN 7012/RfN 7012IN Locking Assemblies can be used in series, the transmissible torques and axial forces are added. (Please contact our specialists for assistance). Bending moment and radial loads ­ Combined loads can be transmitted. (Please contact our specialists for assistance). Simplified manufacture ­ RfN 7012/RfN 7012-IN Locking Assemblies can bridge large clearances without the loss of transmission values. Low risk to contamination ­ During the tightening process the functional surfaces of the device are under pressure, sufficient enough to keep contaminants out, thereby preserving the integrity of the the device. Adjustable transmission values ­ The screw tightening torque can be varied, thus allowing for different torque transmission values. RfN 7012/RfN 7012-IN Locking Assemblies can be tightened and released repeatedly.

Mounting of Locking Assembly The Locking Assemblies are supplied slightly oiled and ready-to-use. The values for T, F ax, PW and PN apply to Locking Assemblies installed in oiled condition. Surface finishes For shafts and hub bores Ra = 125 RMS Tolerances We recommend the following mounting tolerances

shaft: k9-h9 · hub: N9-H9 - see table above shaft: k11-h11 · hub: N11-H11

Location of several Locking Assemblies RfN 7012 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 x L1. Change of screw tightening torques 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 is approximately 50% of TA. There is an approximate linear relationship between T, TA , Fax , pW and pN. Auxiliary Threads To facilitate removal, the front thrust rings have auxiliary threads for pull-out screws.

To avoid deformation 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 true run-out quality is determined by the direct centering between shaft and hub.

Explanations to tables

d, D, L, l, L1, = Basic dimensions, Locking Assemblies not tightened T = transmissible torque

Fax = transmissible axial force pW = surface pressure between Locking Assembly and shaft = surface pressure between Locking Assembly and hub = fastener quantity = clamping thread = metric pullout thread dia. = maximum tightening torque for the screws considered in order to determine the values T, Fax, pW and pN = minimum required outside hub diameter

pN

n dG dD TA

DN

Rp0,2 = minimum required yield point of hub material Tmax = maximum theoretical transmissible torque B = minimum hub width (calculation formula at www.ringfeder.com) = Shaft Tolerances = Bore Tolerances = metric hex key size (across flats)
