Three new N-Eupex couplings and optimised versatile elements

Flender is expanding the portfolio of its flexible coupling sequence N-Eupex by introducing three new types. The new merchandise allow customers additional flexibility in their systems with out losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which offers much more
security in the drivetrain in many purposes. The coupling variant permits customers to
specify a most torque in order that critical torques for the motor and output machine
aren’t transmitted. Machines and methods are shielded from overload and
damage, thus considerably increasing system availability.
With the N-Eupex B plus clamping factor, 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 without a feather key and service capability is increased. For instance,
assembly or replacement of worn elastomers can be carried out far 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 model 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 growth pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened total size allows cost-optimized use with a small shaft distance
dimension with out shedding some great benefits of a double-cardanic coupling connection.

to the beforehand used rubber elements manufactured from NBR, Flender now additionally presents
elastomers manufactured from 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 familiar NBR elastomer is mixed with
cloth inserts and the torque capability is again raised.
“With a view to the long custom of cam couplings, our development engineers are
systematically working on growing the variety of mixtures even further. The
2022 enhancements give our customers a extensive range of sustainable choices for
optimizing their machines and methods even more and decreasing maintenance,”
explains André Artmann, Head of Coupling Sales.
