Three new N-Eupex couplings and optimised flexible components

Flender is increasing the portfolio of its versatile coupling series N-Eupex by introducing three new varieties. The new merchandise permit users further flexibility of their systems with out dropping the compact design and high load capacity of a pin coupling.
The new N-Eupex ERN is supplied with a torque limiter, which provides even more
safety in the drivetrain in plenty of purposes. Elusive coupling variant allows customers to
specify a maximum torque so that important torques for the motor and output machine
are not transmitted. Machines and techniques are protected against overload and
harm, thus significantly increasing 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 connected to the coupling hub through a clamping
connection without a feather key and service capability is elevated. For example,
assembly or substitute of worn elastomers could be carried out far more easily.
No connecting machine components should 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 launched as a “short
version” into Flender’s modular system. While the DK type, which was launched in
2020, addresses the pump market with commonplace expansion pieces for normed shaft
distances, the DKS is the shortest attainable double-cardanic solution for the market.
The shortened overall size allows cost-optimized use with a small shaft distance
dimension with out shedding the 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 components manufactured from NBR, Flender now also offers
elastomers made of 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 increased by another 20 % on
common. For sizes 300 and above, the familiar NBR elastomer is mixed with
material inserts and the torque capacity is once more raised.
“With a view to the long custom of cam couplings, our improvement engineers are
systematically working on growing the number of combos even additional. Protected give our users a variety of sustainable options for
optimizing their machines and systems much more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
