Flender is increasing the portfolio of its versatile coupling collection N-Eupex by introducing three new varieties. The new products permit users further flexibility in their methods with out dropping the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is provided with a torque limiter, which offers even more
safety within the drivetrain in many functions. The coupling variant permits customers to
specify a maximum torque in order that crucial torques for the motor and output machine
aren’t transmitted. Machines and systems are protected against overload and
damage, thus considerably increasing system availability.
With pressure gauge ลม -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 related to the coupling hub via a clamping
connection and not using a feather key and service ability is elevated. For instance,
assembly or replacement of worn elastomers can be carried out rather 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 launched 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 resolution for the market.
The shortened general size permits cost-optimized use with a small shaft distance
dimension without dropping the benefits of a double-cardanic coupling connection.
New elastomers for the pin couplings round off the modular extensions. In addition
to the previously used rubber components made from NBR, Flender now also offers
elastomers made of thermoplastic polyurethane (TPU). Following the torque
enhance for all N-Eupex couplings with NBR packings in 2020, the utilization of TPU
packings allows the power density to be elevated by another 20 % on
common. For sizes 300 and above, the acquainted NBR elastomer is mixed with
fabric inserts and the torque capability is again raised.
“With a view to the lengthy custom of cam couplings, our development engineers are
systematically working on rising the variety of combos even further. The
2022 enhancements give our customers a variety of sustainable options for
optimizing their machines and systems much more and decreasing upkeep,”
explains André Artmann, Head of Coupling Sales.
