Three new N-Eupex couplings and optimised versatile parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise enable users further flexibility of their techniques 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 offers much more
safety in the drivetrain in many purposes. The coupling variant permits users to
specify a maximum torque in order that crucial torques for the motor and output machine
aren’t transmitted. Machines and systems are shielded from overload and
harm, thus considerably rising 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 end is related to the coupling hub via a clamping
connection and not utilizing a feather key and service capability is elevated. For example,
meeting or substitute of worn elastomers may be carried out far more simply.
No connecting machine elements 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 sort, which was launched in
2020, addresses the pump market with standard expansion items for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened general size enables cost-optimized use with a small shaft distance
dimension without losing the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In pressure gauge วัด แรง ดัน น้ำ
to the beforehand used rubber elements made from NBR, Flender now also provides
elastomers made from 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
average. For sizes 300 and above, the familiar NBR elastomer is combined with
cloth inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically working on growing the number of mixtures even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
