Three new N-Eupex couplings and optimised flexible elements

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new products permit customers further flexibility of their techniques without shedding the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which supplies much more
safety within the drivetrain in lots of applications. The coupling variant permits users to
specify a most torque in order that important torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected against overload and
harm, thus considerably rising system availability.
With the N-Eupex B plus clamping element, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is connected to the coupling hub through a clamping
connection without a feather key and repair capability is elevated. For instance,
assembly or replacement of worn elastomers could be carried out far more easily.
No connecting machine elements have to be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a model new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with commonplace growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened total size permits cost-optimized use with a small shaft distance
dimension with out shedding the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber components made of NBR, Flender now also presents
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the facility density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
material inserts and the torque capability is once more raised.
“With เกวัดแรงดันน้ำ to the lengthy custom of cam couplings, our growth engineers are
systematically engaged on rising the number of combinations even further. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and systems even more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
