Three new N-Eupex couplings and optimised flexible parts

Flender is increasing the portfolio of its flexible coupling collection N-Eupex by introducing three new varieties. The new merchandise enable customers extra flexibility of their techniques with out dropping the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which supplies much more
security in the drivetrain in lots of functions. The coupling variant permits users to
specify a most torque in order that critical torques for the motor and output machine
are not transmitted. Machines and systems are shielded from overload and
injury, thus significantly growing 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 end is related to the coupling hub via a clamping
connection and not using a feather key and repair ability is increased. For example,
meeting or substitute of worn elastomers may be carried out much more simply.
No connecting machine components have to be moved, the time required is halved
and so is the downtime of the machine.
With Interesting -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 growth items for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened overall size enables cost-optimized use with a small shaft distance
dimension without dropping some great benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the beforehand used rubber parts made of NBR, Flender now additionally offers
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, using TPU
packings permits the ability density to be increased by another 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
material inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our development engineers are
systematically working on growing the variety of combinations even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and techniques even more and lowering maintenance,”
explains André Artmann, Head of Coupling Sales.
