Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new types. The new products permit customers additional flexibility of their systems without shedding the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies even more
safety within the drivetrain in lots of purposes. The coupling variant allows users to
specify a most torque so that important torques for the motor and output machine
are not transmitted. Machines and methods are protected against overload and
injury, thus significantly rising system availability.
With the N-Eupex B plus clamping factor, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is related to the coupling hub by way of a clamping
connection with no feather key and repair capacity is elevated. For instance,
assembly or substitute of worn elastomers can be carried out much more easily.

and so is the downtime of the machine.
With the N-Eupex DKS, a model new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with standard enlargement items for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened total size allows cost-optimized use with a small shaft distance
dimension with out dropping some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber elements made from NBR, Flender now also presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be increased by another 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically engaged on rising the number of combos even additional. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and systems much more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
