Three new N-Eupex couplings and optimised flexible parts

Flender is expanding the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new products permit users additional flexibility of their systems with out shedding the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers much more
safety within the drivetrain in plenty of functions. The coupling variant permits users to
specify a maximum torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are protected against overload and
injury, 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 through a clamping
connection with no feather key and repair capability is increased. For example,
meeting or alternative of worn elastomers may be carried out far more easily.
No connecting machine components must 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 type, which was launched in
2020, addresses the pump market with normal growth items for normed shaft
distances, the DKS is the shortest potential double-cardanic answer for the market.
The shortened total length allows cost-optimized use with a small shaft distance
dimension with out 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 elements made from NBR, Flender now additionally provides
elastomers made from thermoplastic polyurethane (TPU). Following เพรสเชอร์เกจ
improve for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the ability density to be elevated by one other 20 p.c on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically working on increasing the number of combinations even further. The
2022 enhancements give our users a wide range of sustainable options for
optimizing their machines and methods even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
