Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new products permit users extra flexibility in their systems without shedding the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
security within the drivetrain in many applications. The coupling variant allows customers to
specify a maximum torque so that crucial torques for the motor and output machine
usually are not transmitted. Machines and systems are shielded from overload and
damage, thus considerably rising system availability.
With the N-Eupex B plus clamping component, 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 via a clamping
connection and not utilizing a feather key and repair capacity is elevated. For example,
assembly or alternative of worn elastomers may be carried out much more easily.
No connecting machine components must 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 commonplace enlargement pieces for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened total size permits cost-optimized use with a small shaft distance
dimension with out losing 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 presents
elastomers made of thermoplastic polyurethane (TPU). Following เกจวัดถังแก๊ส
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the facility density to be elevated by another 20 % on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically engaged on growing the variety of mixtures even further. The
2022 enhancements give our users a broad range of sustainable options for
optimizing their machines and methods much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
