RINGFEDER TNS SDDL-5-BSV (REMOVABLE CLAW RINGS, INTERNALLY VENTILATED BRAKE DISK, LONG HUB)

DESCRIPTION: The Ringfeder TNS SDDL-5-BSV coupling is a torsionally flexible, puncture proof claw coupling with removable intermediate part comprising the claw rings with brake disk and the buffer ring. It compensates for angular, radial and axial shaft misalignments within defined limits. The coupling transmits torque through elastic buffers loaded in shear. These buffers come in Perbunan (Pb) or polyurethane (Vk), as a standard Vk60D, and are connected to each other to form an elastic buffer ring. This buffer ring dampens shocks and torsional vibrations and is resistant to oil. Buffer rings made of Perbunan are electrically conductive. The two-parted construction of both coupling halves allows radial mounting and dismounting of the intermediate part. The buffer ring can, therefore, be replaced without having to displace the connected machines. When the intermediate part is removed, it is easily possible to check the rotational direction of the drive. The coupling is suitable for use in every direction of rotation and installation position.

General features
Torsionally flexible, compensate for angular, radial and axial shaft offset
Intermediate rings loaded in compression
Elastomers available in various shore hardness degrees
Suitable for temperatures from –30°C to +100°C
Coupling outer diameter up to 400 mm, brake disc outer diameter up to 1000mm.
Bores up to max. 160 mm
Torques up to TKn = 13,350 Nm / TKmax = 40,000 Nm
Speeds up to nmax = 7,250 rpm

INTRODUCTION
The rotationally resilient coupling of the RINGFEDER TNS coupling is flexible in all directions and therefore compensates for angular, parallel and axial shaft misalignments of the connected machines. Misalignments can be caused, for example, by inaccurate assembly, heat movements or settling phenomena.

Elastic intermediate ring
With the RINGFEDER-TNS coupling, the torque is transmitted via a compressed elastic intermediate ring. The elastic intermediate ring absorbs shocks and torsional vibrations, is resistant to oil and largely insensitive to temperature.
The strength of different elastomer materials is indicated by their Shore hardness. Elastomers of different strengths are colour-coded for identification. Further details concerning the strength and load capacity are available on request in the technical data sheet.

Elastomer Materials
The elastic intermediate rings of RINGFEDER® TNS are made of butadiene-nitril-rubber (Pb82) or polyurethane (VkR, Vk60D). The black buffer (Pb82) are normally electrically conductive and therefore prevent undesirable electrostatic charges. The red (VkR) and white (Vk60D) rings ensure electrical insulation between connected machines as long as there are no other electrically conductive connections. The resilience of the individual elastomer materials is designated by their Shore hardness. From these values an indirect conclusion can be drawn with respect to the torques the coupling is able to transmit and its spring stiffness. For further details, please see the technical data sheet.

Avoiding Torsional Vibration

By virtue of the rotational resilience of the coupling, dangerous torsional vibrations from the operational range of plant machinery can be transferred to rotational speed ranges in which no negative effects are to be expected. The elastic intermediate rings possess a high material damping capability which makes it possible for the couplings to keep the resonance enhancements within limits when passing through dangerous speed ranges, thereby protecting the coupled machines against damage. The couplings also mitigate torque shocks and cause a vibrating system that has been excited by an impact to come to rest very quickly due to the material damping qualities. The conduction of structure-borne noise is prevented.
