Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new products enable customers further flexibility in their methods 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 much more
safety within the drivetrain in plenty of purposes. The coupling variant allows users to
specify a most torque so that important torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected against overload and
injury, 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 through a clamping
connection without a feather key and service ability is elevated. For instance,
meeting or alternative of worn elastomers can be carried out rather more easily.
เครื่องมือวัดความดัน 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 new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with commonplace expansion items for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension with out dropping the 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 of NBR, Flender now additionally presents
elastomers made from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the power density to be elevated by another 20 percent on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capability is again raised.
“With a view to the long tradition of cam couplings, our growth engineers are
systematically working on rising the variety of combinations even additional. The
2022 enhancements give our customers a wide range of sustainable choices for
optimizing their machines and systems much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
