Three new N-Eupex couplings and optimised flexible elements

Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise allow users additional flexibility of their techniques with out dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers much more
safety within the drivetrain in plenty of functions. The coupling variant permits customers to
specify a most torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and systems are protected from overload and
harm, thus significantly 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 linked to the coupling hub via a clamping
connection without a feather key and service ability is elevated. For instance,
meeting or alternative of worn elastomers may be carried out far more simply.
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 model 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 normal enlargement items for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened general size enables cost-optimized use with a small shaft distance
dimension without losing the advantages 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 offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be elevated by another 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With เกจวัดแก๊ส to the long custom of cam couplings, our development engineers are
systematically engaged on rising the variety of combinations even further. The
2022 enhancements give our customers a wide range of sustainable choices for
optimizing their machines and techniques even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
