Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new sorts. The new products permit customers further flexibility of their techniques without shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides much more
safety in the drivetrain in many functions. The coupling variant permits customers to
specify a most torque in order that crucial torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
injury, thus significantly rising system availability.
With the N-Eupex B plus clamping factor, 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 by way of a clamping
connection and not utilizing a feather key and repair ability is elevated. For instance,
meeting or substitute of worn elastomers can be carried out much more easily.
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 introduced as a “short
version” into Flender’s modular system. While the DK sort, which was launched in
2020, addresses the pump market with normal expansion items for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened overall size permits cost-optimized use with a small shaft distance
dimension with out shedding the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In เกจวัดแรงดันอากาศ
to the beforehand used rubber parts made of NBR, Flender now additionally offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the usage of TPU
packings permits the facility density to be elevated by one other 20 % on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is again raised.
“With a view to the lengthy custom of cam couplings, our growth engineers are
systematically engaged on increasing the variety of mixtures even additional. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and systems even more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
