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 products enable customers further flexibility of their techniques without dropping the compact design and excessive load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which supplies much more
safety within the drivetrain in lots of purposes. The coupling variant allows customers to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and techniques are shielded from overload and
injury, thus considerably 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 by way of a clamping
connection with no feather key and service ability is increased. For instance,
assembly or substitute of worn elastomers may be carried out far more simply.
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 kind, which was launched in
2020, addresses the pump market with normal enlargement pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic answer for the market.
The shortened total length enables cost-optimized use with a small shaft distance
dimension with out shedding the advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber parts made of NBR, Flender now additionally provides
elastomers made from thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings permits the power density to be increased by another 20 p.c on
average. For Billion and above, the acquainted NBR elastomer is combined with
cloth inserts and the torque capability is once more raised.
“With a view to the lengthy tradition of cam couplings, our improvement engineers are
systematically working on rising 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 reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
