Three new N-Eupex couplings and optimised versatile components

Flender is expanding the portfolio of its versatile coupling sequence N-Eupex by introducing three new sorts. The new merchandise enable users additional flexibility in their systems without losing the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more
safety within the drivetrain in lots of applications. The coupling variant allows customers to
specify a maximum torque in order that crucial torques for the motor and output machine
are not transmitted. Machines and systems are shielded from overload and
damage, thus considerably growing system availability.
With the N-Eupex B plus clamping element, 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 through a clamping
connection without a feather key and repair capacity is elevated. For Luxurious ,
assembly or replacement of worn elastomers can be carried out much more simply.
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 model 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 normal enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened total size permits cost-optimized use with a small shaft distance
dimension with out dropping 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 from NBR, Flender now additionally provides
elastomers made from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the facility density to be increased by one other 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is once more raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically working on increasing the number of combos even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
