Three new N-Eupex couplings and optimised versatile components

Flender is expanding the portfolio of its versatile coupling collection N-Eupex by introducing three new types. The new products enable users additional flexibility in their techniques without losing the compact design and excessive load capability of a pin coupling.
Hurry -Eupex ERN is equipped with a torque limiter, which provides much more
security in the drivetrain in plenty of functions. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
usually are not transmitted. Machines and techniques 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 related to the coupling hub through a clamping
connection with no feather key and service capability is elevated. For example,
meeting or substitute of worn elastomers may be carried out rather more simply.
No connecting machine components should 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 kind, which was launched in
2020, addresses the pump market with commonplace enlargement 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 dropping some great 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 components made from NBR, Flender now also presents
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be elevated by one other 20 p.c 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 custom of cam couplings, our growth engineers are
systematically working on growing the number of combos 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.
