Flender is expanding the portfolio of its versatile coupling series N-Eupex by introducing three new types. The new products enable users extra flexibility of their techniques with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides even more
safety within the drivetrain in plenty of functions. The coupling variant permits users to
specify a maximum torque so that important torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
damage, thus considerably increasing 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 linked to the coupling hub by way of a clamping
connection and not using a feather key and repair capacity is increased. For instance,
assembly or substitute of worn elastomers may be carried out much more easily.
No connecting machine elements should 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 introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with normal growth items for normed shaft
distances, the DKS is the shortest potential double-cardanic resolution for the market.
The shortened general length permits cost-optimized use with a small shaft distance
dimension without dropping the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber components made of NBR, Flender now additionally offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the ability density to be elevated by another 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
material inserts and the torque capacity is again raised.
“With pressure gauge ด้าน ดูด to the long custom of cam couplings, our development engineers are
systematically engaged on growing the number of combos even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems much more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
