Three new N-Eupex couplings and optimised flexible elements

Flender is increasing the portfolio of its flexible coupling sequence N-Eupex by introducing three new varieties. The new merchandise enable users extra flexibility in their techniques with out shedding the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides much more
safety within the drivetrain in lots of purposes. The coupling variant permits users to
specify a maximum torque in order that critical torques for the motor and output machine
are not transmitted. Machines and techniques are protected from overload and
injury, thus considerably rising 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 by way of a clamping
connection and not using a feather key and repair capability is elevated. For instance,
assembly or replacement of worn elastomers can be carried out much 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 growth items for normed shaft
distances, the DKS is the shortest possible double-cardanic solution for the market.
The shortened total length permits cost-optimized use with a small shaft distance
dimension without dropping the advantages of a double-cardanic coupling connection.

to the beforehand used rubber elements manufactured from NBR, Flender now additionally offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
improve for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the facility density to be elevated by another 20 percent on
average. For sizes 300 and above, the familiar NBR elastomer is combined with
fabric inserts and the torque capacity is once more raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically engaged on rising the number of mixtures even additional. The
2022 enhancements give our users a broad range of sustainable options for
optimizing their machines and methods even more and reducing maintenance,”
explains André Artmann, Head of Coupling Sales.
