Ringfeder Internal Locking Devices

pdf

Ringfeder? locking devices are unique keyless, frictional shaft-hub locking devices which provide an easily-adjustable and

releasable shrink fit.

Advantages:

Elimination of keys and keyways on both shafts and hubs

No backlash - completely tight fit around the shaft

Unaffected by reversing, dynamic or shock loads.

Easy assembly and disassembly.

Ease of axial and angular adjustment or timing.

Reduced machining costs.

Working Principle:

Ringfeder devices utilize the inclined plane or the taper principle. Clamping forces generated by the torquing of locking screws

are translated into precisely-calculated predetermined radial contact pressures. This creates a very robust yet releasable

mechanical shrink-fit connection.

RfN 7012 Locking Assemblies

Sizes for shafts from ?" to 7.875" diameter and 20 mm to 1000 mm diameter available off the shelf. Larger sizes are available upon request.

double-tapered thrust rings with self-releasing tapers

bridge relatively large clearances fits

easy to handle, adjust or remove but not self-centering, therefore, a pre-centering hub section is usually required.

Pilot bushings available to provide better pre-centering for applications with straight-through hub bore or narrow hubs.

Commonly used on applications in general engineering to transmit high torques and axial loads utilizing larger machining tolerances RfN 7013 Locking Assemblies

Sizes for shafts from 1" to 4" diameter and 20 mm to 150 mm diameter

Single-tapered design with self-locking taper providing good self-centering action and concentricity and increased torque capacity

Available as straight-thru type - RfN 7013.0 and flange type - RfN 7013.1 which fixes the hub positively against the extended flange preventing axial movement during tightening
