Flender is expanding the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new products permit customers further flexibility of their systems without losing the compact design and high load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which supplies even more
safety in the drivetrain in plenty of purposes. The coupling variant permits users to
specify a maximum torque so that critical torques for the motor and output machine
usually are not transmitted. Machines and techniques are protected against overload and
harm, 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 finish is linked to the coupling hub through a clamping
connection with no feather key and service capacity is elevated. For example,
meeting or alternative of worn elastomers may be carried out rather more easily.
No connecting machine parts 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 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 resolution for the market.
The shortened general length allows cost-optimized use with a small shaft distance
dimension with out losing some great advantages of a double-cardanic coupling connection.
New elastomers for the pin couplings spherical off the modular extensions. In addition
to the previously used rubber parts manufactured from NBR, Flender now additionally presents
elastomers made from thermoplastic polyurethane (TPU). Following xp2i for all N-Eupex couplings with NBR packings in 2020, the use of TPU
packings allows the ability density to be increased by one other 20 p.c on
common. For sizes 300 and above, the acquainted NBR elastomer is combined with
fabric inserts and the torque capacity is again raised.
“With a view to the long tradition of cam couplings, our improvement engineers are
systematically working on rising the variety of mixtures even additional. The
2022 enhancements give our customers a extensive range of sustainable options for
optimizing their machines and methods even more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
