Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new types. The new merchandise permit customers extra flexibility in their methods without dropping the compact design and excessive load capacity of a pin coupling.
Child’s play -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 in order that crucial torques for the motor and output machine
are not transmitted. Machines and techniques are shielded from overload and
harm, thus significantly growing 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 by way of a clamping
connection with no feather key and repair capacity is increased. For instance,
meeting or substitute of worn elastomers may be carried out far more easily.
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 introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with standard expansion items for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened total size enables cost-optimized use with a small shaft distance
dimension without dropping some great advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber elements manufactured from NBR, Flender now additionally offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the ability density to be elevated by another 20 p.c on
common. 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 lengthy tradition of cam couplings, our growth engineers are
systematically working on increasing the variety of mixtures even additional. The
2022 enhancements give our customers a extensive range of sustainable choices for
optimizing their machines and techniques much more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
