Three new N-Eupex couplings and optimised flexible components

Flender is increasing the portfolio of its flexible coupling series N-Eupex by introducing three new sorts. The new merchandise permit customers additional flexibility in their systems with out shedding the compact design and excessive load capability of a pin coupling.
The new N-Eupex ERN is equipped with a torque limiter, which provides even more
security in the drivetrain in many functions. The coupling variant allows users to
specify a most torque so that crucial torques for the motor and output machine
are not transmitted. Machines and methods are protected from 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 linked to the coupling hub through a clamping
connection without a feather key and service ability is elevated. For instance,
meeting or replacement of worn elastomers can be carried out far more simply.
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 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 enlargement items for normed shaft
distances, the DKS is the shortest possible double-cardanic answer for the market.
The shortened total size enables cost-optimized use with a small shaft distance
dimension without shedding the 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 provides
elastomers manufactured from thermoplastic polyurethane (TPU). Following the torque
increase for all N-Eupex couplings with NBR packings in 2020, using TPU
packings allows the power density to be increased by one other 20 % on
average. For sizes 300 and above, the familiar NBR elastomer is combined with
cloth inserts and the torque capability is once more raised.
“With a view to the long tradition of cam couplings, our development engineers are
systematically working on increasing the variety of mixtures even further. pressure gauge digital ราคา give our users a wide range of sustainable choices for
optimizing their machines and techniques much more and reducing upkeep,”
explains André Artmann, Head of Coupling Sales.
