Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new sorts. Deadline enable users extra flexibility of their techniques with out losing the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers much more
safety in the drivetrain in plenty of functions. The coupling variant allows users to
specify a maximum torque in order that critical torques for the motor and output machine
usually are not transmitted. Machines and systems are shielded from 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 end is related to the coupling hub through a clamping
connection and not utilizing a feather key and repair capacity is elevated. For example,
assembly or substitute of worn elastomers may be carried out far more easily.
No connecting machine parts have to be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a new double-cardanic coupling is launched as a “short
version” into Flender’s modular system. While the DK sort, 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 resolution for the market.
The shortened total length 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 round off the modular extensions. In addition
to the previously used rubber parts made of NBR, Flender now additionally provides
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the facility density to be elevated by another 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically working on increasing the number of mixtures even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and systems much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
