2 Function
The coupling
RINGFEDER
®
TNM E
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 of 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.
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 740 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 repre-
sent a risk for the operational safety of the coupling. Consult
RINGFEDER POWER
TRANSMISSION
in 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.
