2 Function

The coupling

RINGFEDER

TNM G

is a torsionally elastic and puncture-proof claw

coupling.

It balances out angular, radial, and axial shaft misalignments within defined limits. The

coupling transfers the torque via pressure loadable, elastic buffers or Perbunan (Pb) which

are joined together as an intermediate ring.

The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-tight and

electrically conductive.

A coupling half is divided in two and allows through this a simple separation of the coupled

machine. With the claw ring pulled back it is possible to check the rotational direction of the

drive. It is also possible to lift out radially a coupling half with accompanying aggregate. The

elastic intermediate ring can be changed without axially shifting the machine.

The coupling is usable in every sense of rotation and installation position.

2.1 Appropriate Use



In order to ensure a faultless, lasting operation of the coupling it must be laid out accord-

ing to the layout instructions e.g. DIN 730 part 2 (or also

Product Paper & Tech Paper



”Elastomer Jaw Couplings“

) with an

operating facture corresponding to the operating

conditions.



The coupling must only be operated in normal industrial atmospheres. Since aggressive

media may attack the coupling components, screws and elastic buffer rings, they

represent a risk for the operational safety of the coupling. Consult

TRANSMISSION

such cases.



Apart from incorporating a finished bore hole with parallel key groove (see “7.2 Finished

borehole”) no further changes can be carried out on the coupling.



The coupling may only be used within the framework of the conditions defined in the

performance and delivery contract.



Every change of the conditions of use or the operating parameters necessitates a new

verification of the coupling layout.
