Powerful and compact
Torque transmission is possible by means of PETER shrink-on disks.
The principle is thoroughly convincing especially in input and output connections by means of hollow shafts. Contrary to keyed connections, the non-positive connection by means of shrink-on disks permits considerably thinner wall thicknesses for the hollow shafts since the greatest part of the torque transfer is absorbed by the shrink-on disk and the shaft is not weakened by additional slots.
This results in lower shaft diameters and consequently volumetric savings in the remaining system. Weight, moments of inertia and space can be elegantly saved in this manner.
Other factors in favour of shrink-on disks are
• high performance density
• detachable connection
• rapid and simple assembly
• economic use

CHARACTERISTICS
1. SLIT INNER RING
Low load losses and pressures on the hub.
2. BALANCING OF SMALLER DEVIATIONS IN TOLERANCES
For more information please contact our Technical Department.
3. HIGHEST RELIABILITY
Applicable for static, dynamic and impact loads.
4. SIMPLE MANUFACTURE OF THE COMPONENTS
Only low demands are made to the functional surfaces of the clamped
parts.
5. ABSOLUTE INTERCHANGEABILITY
Shrink Discs RINGFEDER® operate without any form closure.
6. EASY MOUNTING
Machining or fitting work is not required, standard tools suffice.
7. SHORT ASSEMBLY TIMES
Cost savings especially in serial production.
8. EASY REMOVAL
After loosening of the locking screws, the Shrink Disc RINGFEDER® is
released. The hub can be moved on the shaft freely.
9. LOW SUSCEPTIBILITY TO CONTAMINATION
Increased durability, as after tightening of the locking screws the
contact surfaces are pressed firmly together. Dirt and moisture cannot
ingress the functional surfaces.

Clamping sets constitute a particularly elegant way of a shaft/hub connection. They combine the advantages of a no-play clamped connection that is detachable, a high capacity for torque transmission and minimum structural and manufacturing requirements of the system to be clamped.
Ideal applications for instance arise in the assembly of:
• gears
• V-belt pulleys
• sprockets
• belt pulleys
• couplings or
• levers

CHARACTERISTICS
1. SIMPLE MANUFACTURE
Large possible tolerances and simple turning treatment guarantee
cost-efficient production.
2. EASY MOUNTING
Only a few screws must be tightened, angle-exact alignment between
hub and shaft is possible in every position, fitting work is not required.
3. EASY REMOVAL
RINGFEDER® Locking Assemblies have releasing threads, thus no
additional auxiliary devices are required. Series 7012 is even self-
releasing (no releasing threads).
4. HIGH FATIGUE STRENGTH UNDER ALTERNATING TORSIONAL STRESSES
Neither shaft nor hub feature grooves, thus no attenuation of the
components. Shaft and hub can be designed definitely smaller (light,
cost- and space-saving construction is possible).
5. NO DANGER OF DEFLECTION
Locking Assemblies RINGFEDER® are absolutely free from backlash.
6. OVERLOAD PROTECTION EFFECT
In case the admissible load is exceeded, the Locking Assemblies will
slip. That way, valuable machine components are safeguarded against
damage. However, the Locking Assemblies are subject to the same
laws as all other frictional locking connections and are not suitable for
use as friction clutch.
