locking assembly

Special Solution Locking Assemblies

Where the use of standard Locking Assemblies is not sufficient we develop special solutions optimised to specific customer requirements so that the parts are ideal for the specific application. In this way it is possible to make use of applications which were not previously possible.

 


RfN 7012

Characteristics

As the industry standard the RfN 7012 stainless Locking Assembly is suitable lor most applications.


Special Features
Transmission of high loads -up to 4 RfN 7012 stainless Locking Assemblies can be used in series, the transmissible torques and axial forces are added.

Bending moment and radial loads - Combined loads can be transmitted, please contact our specialist for assistance.

Low risk to contamination -during tightening process the functional surfaces ot the device and connsection are pressed together generating a surface pressure that does not allow the ingress of contamination.

Adjustable transmission values - the locking screw torque can be changed giving a corresponding change in transmission values. RfN 7012 stainless Locking Assemblies can be tightened and released repeatedly.

Example applications: chain wheels, levers, pulleys, slip-on gear mechanisms, belt drums, running wheels, cable sheaves

 


RfN 7015.0

Characteristics

Precision Locking Assembly for the transmission of maximum torques and axial forces with special demands on the concentricity of the parts of the clamped, as well as for applications subjected to bending moments.


Special Features
Large transmittable peripheral forces - Due to the long, flat cones it is possible to transmit maximum torques and axial forces with one RfN 7015.0 Locking Assembly

Bending moment and radial loads - Combined loads can be transmitted,please contact our specialists for assistance.

During installation the Locking Assembly shaft and hub remain in position to one another. The shaft and hub are only compression-loaded, providing additional safety compared to 3-part versions.

Excellent centering ability - with relatively a wide design (giving increased guiding lengths) and the precentering web the RfN 7015.0 Locking Assembly has excellent centering ability.

 

Example applications: belt drums, crusher rotors, precision drives


Ecoloc 7006

Characteristics

 

With the new product class ECOLOC® you obtain a cost-optimized Locking Element™ that offers a sensational price-quality ratio altogether with a high level of safeness.
Other sizes available upon request.
d x D, D1, Ltot, L, L1, L2 = basic dimensions, Locking Assembly™ in loose conditions.
dG = clamping & releasing threads
T = transmissible torques
Fax = transmissible axial forces
p = surface pressure between Locking Assembly™ and shaft
p' = surface pressure between Locking Assembly™ and hub
TA = for determining T, Fax, p and p' allowed maximum permissible screw tightening torque

RfN 7015.1

Characteristics

Locking Assembly for transmission of torques, axial forces and high bending moments at reduced contact pressures, with special requirements to the true running of the clamped pieces.


Special Features
Low surface pressures- the RfN 7015.1 Locking Assembly can transmit torques and axial forces and bending loads with significantly surface pressures.

Bending moment and radial loads - Combined loads can be transmitted, please contact our specialists for assistance.

Excellent centering ability - with relatively a wide design (giving increased gui­ding lengths) and the precentering web the RfN 7015.1 Locking Assembly has excellent centering ability.

 

Example applications: belt drums, gear wheels
