Three new N-Eupex couplings and optimised flexible components

Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new products enable customers additional flexibility in their systems with out shedding 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 in the drivetrain in lots of purposes. ราคาpressuregauge coupling variant allows users to
specify a most torque in order that important torques for the motor and output machine
usually are not transmitted. เครื่องมือวัดpressure and methods are shielded from overload and
damage, thus considerably growing 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 end is related to the coupling hub by way of a clamping
connection without a feather key and repair ability is elevated. For example,
assembly or alternative of worn elastomers could be carried out far more simply.
No connecting machine parts should be moved, the time required is halved
and so is the downtime of the machine.
With the N-Eupex DKS, a brand 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 commonplace expansion items for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension with out shedding some nice benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the beforehand used rubber components made of NBR, Flender now also provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings permits the power density to be elevated by one other 20 % on
common. 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 long custom of cam couplings, our development engineers are
systematically working on growing the variety of mixtures even further. The
2022 enhancements give our customers a variety of sustainable choices for
optimizing their machines and systems much more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
