The user must take into account that the bolting elements of coupling parts may be adversely
affected by the heat produced by a brake disk/ brake drum due to the resultant friction. Make
sure that the combination of the employed brake lining with the material of the brake disk/
brake drum does not lead to sparks or impermissible thermal growth. The brake disk is
normally made of steel, and the brake drum is normally made of cast iron with nodular
graphite. In case of any doubt, please consult the supplier!
In the interest of further development, we reserve the right to make changes which serve
technological progress.
By the use of accessories and spare parts, which were not originally manufactured by
RINGFEDER POWER TRANSMISSION, we are not responsible for any resulting damage or
liability or guarantee.
2 Function
The coupling RINGFEDER
®
TNM GBT, TNM GTW 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 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
·
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 RINGFEDER
POWER TRANSMISSION in such cases.
·
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.
·
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.
