Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new sorts. The new merchandise permit customers further flexibility of their methods with out losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which provides even more
safety within the drivetrain in lots of functions. The coupling variant permits users to
specify a most torque in order that crucial torques for the motor and output machine
aren’t transmitted. Machines and methods are shielded from overload and
damage, thus considerably growing 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 connected to the coupling hub through a clamping
connection without a feather key and service capacity is increased. For pressure gauge ด้าน ดูด ,
assembly or replacement of worn elastomers may 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 standard enlargement 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 dropping the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber parts made of NBR, Flender now additionally presents
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be increased by another 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is combined with
material inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our growth engineers are
systematically engaged on growing the variety of combos even additional. The
2022 enhancements give our users a variety of sustainable choices for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
