Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new varieties. The new merchandise permit users extra flexibility in their systems without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which offers much more
security in the drivetrain in plenty of applications. The coupling variant permits users to
specify a most torque so that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected from overload and
damage, thus significantly rising system availability.
With the N-Eupex B plus clamping component, Flender introduces a second new
coupling that ensures frictionally engaged clamping connections. In this case, the
plain, cylindrical machine shaft finish is linked to the coupling hub via a clamping
connection and not using a feather key and repair capacity is elevated. For instance,
assembly or alternative of worn elastomers can be carried out rather more easily.
เพรสเชอร์เกจ connecting machine elements must be moved, the time required is halved
and so is the downtime of the machine.
With ไดอะแฟรม ซีล -Eupex DKS, a new double-cardanic coupling is introduced as a “short
version” into Flender’s modular system. While the DK kind, which was launched in
2020, addresses the pump market with standard expansion pieces for normed shaft
distances, the DKS is the shortest potential double-cardanic solution for the market.
The shortened total length permits cost-optimized use with a small shaft distance
dimension with out dropping some nice 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 parts manufactured from NBR, Flender now also provides
elastomers made of thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the power density to be increased by another 20 % on
average. For sizes 300 and above, the familiar NBR elastomer is mixed with
cloth inserts and the torque capability is again raised.
“With a view to the lengthy custom of cam couplings, our development engineers are
systematically engaged on growing the variety of mixtures even further. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and methods even more and lowering upkeep,”
explains André Artmann, Head of Coupling Sales.
