Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new varieties. The new products enable users extra flexibility of their methods without dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more
safety within the drivetrain in many purposes. The coupling variant allows users to
specify a maximum torque so that crucial torques for the motor and output machine
usually are not transmitted. Machines and methods are protected from overload and
damage, thus significantly increasing 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 linked to the coupling hub via a clamping
connection and not using a feather key and repair capacity is elevated. For example,
assembly or substitute of worn elastomers can be carried out much more simply.

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 type, which was launched in
2020, addresses the pump market with normal growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened total length allows cost-optimized use with a small shaft distance
dimension with out losing some nice benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber parts made from NBR, Flender now additionally offers
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the facility density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically working on rising the number of mixtures even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and methods much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
