RINGFEDER TNS SDDL-5-BS (REMOVABLE CLAW RINGS, BRAKE DISK, LONG HUB)

Flexible Coupling TNS SDDL-5-BS

The RINGFEDER TNS SDDL-5-BS coupling is a torsionally flexible, fail-safe claw coupling with removable intermediate part comprising the claw rings with brake disk and the buffer ring. It balances out angular, radial and axial shaft misalignments within defined limits. The coupling transfers the torque via pressure loadable, elastic buffers of synthetic rubber (Pb) or polyurethane (Vk), as a standard VkR, and are connected to each other to form an elastic intermediate ring. The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-resistant. Intermediate 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 intermediate ring and the brake disc 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.

RINGFEDER TNS SDDL-5-BS

Multi-part design coupling with flange hubs, detachable claw rings and full brake disc. The intermediate ring and the brake disc can be replaced by removing the claw rings without moving a shaft.

Notes 
Standard material for intermediate ring: Vk60D
Installed size L must be maintained without fail. Axial displacement e.g. by thermal expansions of the connected shafts, must be taken into account through allowances for value L.

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.
